Abstract:
Australia's Murray-Darling Basin is extremely important for its economic, resource, environmental and ecological values. The two most important rivers- River Murray and River Darling crosses through the basin. In recent years, due to the “millennial drought”, a series of ecological and environmental problems such as rising salinity, large fish death events and soil acidification phenomenon have caused a shortage of freshwater resources in the downstream Adelaide region. This paper draws lessons from the failure of the design of the downstream Alexander Lake’s reservoir, and attempts to improve the regional natural environment and water supply ability through the application of multi-purpose coastal reservoir technology. So that the Adelaide region has sufficient high-quality drinking water supply to alleviate the phenomenon of river dryness in the region. Trying to improve regional natural environment and water supply environment by applying multi-purpose coastal reservoir technology. In addition, through the research of coastal reservoir technology, it provides suggestions for the improvement of natural environment and water supply ability in China's coastal areas, and realizes the effective management of China's freshwater resources.

Abstract:
The biomass distribution characteristics of total bacteria, aerobic ammonium-oxidizing and denitrifying bacteria in sediments from Changjiang Estuary and adjacent sea area were analyzed using DAPI staining and fluorescent quantitative PCR technology. For the vertical distribution, denitrifying bacteria (DB) biomass was much higher than that of aerobic ammonium-oxidizing bacteria (AOB) at the same depth, but there were similar trends between their vertical biomass. The intense mixing of sediments was suitable for AOB coexisting with DB. Sediment depth was the most significant influencing factor to the vertical biomass profiles of total bacteria, AOB and DB. The increasing depth affected AOB more easily than total bacteria and DB. For the horizontal distribution, total bacterial biomass gradually decreased from inshore to offshore, which was significantly impacted by the nitrite concentration. There were high biomass areas of AOB and DB in the sea area off Changjiang Estuary and the south sea area of Zhoushan Archipelago, respectively, and dissolved oxygen concentration and total nitrogen content were important influencing factors to their horizontal distributions. This study provided support for thoroughly understanding the role of bacteria in nitrogen cycles in estuarine and coastal sea area.

Abstract:
In order to evaluate the purification capacities of DIN and DIP in different types of wetlands in two typical semi-closed bays (Jiaozhou bay and Daya bay) in China, a quantitative method of seawater-groundwater interactions was used to calculate the purification capacities. Results showed that: there are four types of wetland in Jiaozhou bay, i.e., sandy beaches, mud flat, estuarine intertidal zone and tidal marsh, and their purification capacities on DIN sort as follows: mud flat>sandy beaches>estuarine intertidal zone> tidal marsh and DIP sort as follows: sandy beaches>mud flat>estuarine intertidal zone> tidal marsh. The purification rate ranged from 2.11×105 mol/d to 4.23×105 mol/d for DIN and from 4.29×102 mol/d to 8.22×102 mol/d for DIP, respectively. The estimated nitrogen removal rate due to human activities such as land reclamation was 3.1~5.4 t/d. In contrast, there are three types of wetlands such as mangrove swamp, sandy beaches and silt-sandy beaches in Daya bay. The DIN purification capacities of different types of wetlands in Daya bay sort as follows: mangrove swamp>sandy beaches>silt-sandy beaches, with an average of 4.22×107 mol/d. Due to the area decrease of mangrove swamp and sandy wetlands in Daya bay, the decreased nitrogen removal rate was estimated to be 1.33×102 t/d and 0.81 t/d, respectively.

Abstract:
Amino acids, as one of the most important readily bioavailable components in marine organic nitrogen pool, have attracted more and more attention with the deepening understanding of the biogeochemical cycle of organic nitrogen in the marine environment. Studies on composition and bioavailability of amino acids are of great significance to understand the migration and transformation of organic nitrogen in the ocean. In this paper, the advances in analytical methods for dissolved amino acids in seawater, such as spectrophotometry and fluorospectrophotometry and separation methods, such as Ion Exchange Chromatography (IEC) and High-performance Liquid Chromatography (HPLC) are detailed explained. And the most widely used precolumn derivatives-reversed-phase liquid chromatography-fluorescence detection method is more detailed reviewed. Moreover, the latest techniques such as Mass Spectrometry (MS), Compound-Specific Isotope Analysis (CSIA) and Capillary Electrophoresis (CE) are also mentioned, as well as their prospected applications in oceanography.

Abstract:
In order to monitoring on the dissolved oxygen (DO) status of different water layers in marine ranching in the real-time, online and continuous, this paper designs a multi-layer marine dissolved oxygen online monitoring system. It integrates an optical dissolved oxygen sensor developed independently and designed the chain-type DO section measurement structure. The data acquisition and control system is designed based on STM32 single-chip. And the wireless transmission module communicating with the remote control center is used to complete the real-time update and visual display of the data, which realize the expression of the remote control command to the monitoring system. The results show that the drift of DO probe can be controlled within 3%, and the whole system displayed the good stability, high reliability. It is convenient for users to check the current dissolved oxygen status of seawater and view historical data. In 2016 to 2018, the system has been applied to the east ocean Yunxi marine ranching in Yantai, Shandong. The observation data shows that DO and temperature show similar laws. The concentration of DO in the surface water is high with small variation range. The variation range of DO in the middle sea water is obviously higher than that in the surface layer and the bottom layer. And the DO in the bottom sea water shows a continuous downward trend without obvious vertical mixing. During the observation period, the bottom sea water of marine ranching appeared hypoxia for more than 18 days in 2016 and 2017, and the time series change trend of the test data is consistent with the weather change, which provide early warning and forecast for the aquaculture enterprises of marine ranching and reduce the economic loss caused by hypoxia disaster.

Accepted Manuscript  doi: 10.12111/j.mes.20190231
[Abstract](59) [FullText HTML](63) [PDF 639KB](2)
Abstract:
Coccolithophores are one of the marine phytoplankton functional groups, playing important roles in the marine carbon cycle through both photosynthetic and calcification processes. The oceans are considered as important sink of the anthropogenic CO2. The rapid increase in atmospheric pCO2 since the industrial revolution has caused the trend of global climate change, including ocean acidification, global warming and changes in the nutrient concentrations and irradiance in the mixed layer. These complex changes in environmental conditions will affect the physiology and ecology of marine phytoplankton simultaneously, which is the so-call environmental multiple stress. The response of coccolithophores to changes in multiple environmental drivers will also have complex feedback to marine carbon cycle. This review mainly overviews the current understanding of the effects of both single environmental driver (CO2 concentration, temperature, and nutrient and irradiance levels) and the interaction of multiple environmental drivers on the physiology of coccolithophores and its implications on the marine biogeochemistry. Based on these recent research advances, the future research perspectives are also summarized.

Abstract:
The spatial and temporal distributions of environmental ecological parameters (including salinity, nutrients and chlorophyll a) were investigated in the Guanghai bay during two cruises in October 2014 (autumn) and April 2015 (spring). The state of eutrophication in this region were evaluated by eutrophication index (EI) and nutrient quality state index (NQI). The relationships among nutrients, the N/P ratio, phytoplankton biomass and population structure were discussed in order to provide an improved understanding of the influence of environmental factors on coastal eutrophication. The spatial distributions of nutrients displayed a declining trend from the coastal estuary toward the marine environment in spring, which was primarily affected by the sewage discharge of Datong river. In autumn, the concentrations of nutrients were higher in the northwestern regions, compared with those in the southeastern area. These findings suggest an extremely dynamic cycling of nutrients that responds rapidly to changes in the phytoplankton biomass and community structure. Eutrophication occurred in Guanghai bay during spring and autumn, with a decreasing gradient from inshore to offshore sites. Eutrophication situation worsened obviously from spring to autumn.

Abstract:
Heavy metal elements are persistent pollutants which are easy to be accumulated in the environment. Those poisonous pollutions will cause serious threats to ecological security and human health because of their long-term accumulation in environment, especially in the surface sediments. To find out the effect of social and economic development on the mangrove wetlands, correlation analysis was used to address how heavy metal contents in mangrove wetlands were affected by surrounding land use/cover types, social and economic development indicators and pollutant emission of different cities in Hainan Island. The result showed there were significantly positive correlations between Zn, Ni, Hg, and Co, indicating that those heavy metal elements may come from the same or similar sources. Furthermore, it was found that both Zn and Cu contents increased with the increasing of construction land area; Cu、Zn、Hg are significantly positively correlated with GDP, while Cu and Zn are significantly positively correlated with permanent population. All mentioned above results of correlation analysis generally showed those heavy metal elements may come from urban construction and vehicle exhaust.

[Abstract](64) [FullText HTML](48) [PDF 1257KB](0)
Abstract:
Total phosphorus of three columnar sediments in Zhejiang offshore was measured. A sequential extraction method (SEDEX) was adopted to measure phosphorus of 5 forms in the columnar sediments. 210Pb method was used to measure the deposition rate. Age-dating results were combined with some climatic or human activity events to analyze the vertical distribution characteristics of total phosphorus, inorganic phosphorus and phosphorus of 5 forms, and degradation of organic phosphorous. The research results indicated that vertical distribution characteristics of phosphorus in various forms at different stations were different, relating to the sedimentary environment and diagenesis. Organic phosphorous in the core sediments showed the rapidly declining trends in the surface layer or sub-surface, indicating that degradation of organic phosphorous mainly occurred in the surficial aerobic zone and sub-surface.

[Abstract](60) [FullText HTML](49) [PDF 1115KB](1)
Abstract:
The distribution trend and influence of particulate mercury (PHg) and dissolved mercury (DHg) in adjacent waters of the Yangtze River Estuary were studied by the Science 3 scientific research vessel in July and October 2018, respectively. The results showed that PHg and DHg had a large variance in the surface seawater, and the difference was obvious in different seasons. In summer, PHg in surface water decreased from nearshore to the open seas. In the autumn period, this trend was not obvious. DHg accounted for a larger proportion in this sea area. DHg was higher in autumn than that in summer, and the surface water was higher than the bottom water. In summer, the particle-water partition coefficients in surface and the bottom water increased from nearshore to the open seas; PHg correlated with TSM significantly in the surface and bottom water and PHg/TSM increased exponentially with salinity (R2=0.3365, p<0.01). The main reason for the change in the temporal and spatial distribution of surface PHg was the decrease of Changjiang diluted water and more windy weather. The distribution characteristics of DHg were controlled by small particle diameter and more marine organic particles. While the higher concentration of DHg at 30°N reflected the effects of river transport and surrounding pollution discharge.

Abstract:
This paper studies the spatial distribution of aquaculture areas in Sansha bay and the impact of aquaculture area changes on water quality in the area, so as to provide scientific basis for water quality environmental protection and sustainable development of aquaculture industry in Sansha bay. It carries out the classified extraction and statistics of remote sensing images of Sansha bay in 2007-2019 by cage aquaculture area and algae aquaculture area, and analyzes the dynamic changes of the area and distribution of two kinds of aquaculture. Besides, it predicts the water quality data of Sansha bay in 2019 by time series analysis model, and conducts the correlation analysis between aquaculture and water quality based on the dynamic changes of water quality and aquaculture area from 2007 to 2019. The results show that the area of aquaculture appeared an overall growth trend from 2007 to 2019. Algae aquaculture area increased rapidly from 2007 to 2014, basically covering the whole Sansha bay area, while it remained stable from 2014 to 2019. And cage aquaculture area continued to increase from 2007 to 2019, which gradually expanded to the waters near Dongan island and Dongchongkou. The change trend of water quality and aquaculture area in 2007-2018 is basically the same, so qualitative and quantitative analysis has verified that there is a certain correlation between water quality and aquaculture area in Sansha bay, and it is further verified by water quality prediction in 2019.

[Abstract](158) [FullText HTML](89) [PDF 742KB](1)
Abstract:
The temporal and spatial distribution of petroleum hydrocarbon of surface sediment of offshore marine areas in Liaodong Bay was examined based on the concentrations retrieved from marine environmental monitoring data from 2015 to 2017. The source and degree of pollution were also analyzed and discussed. The results show that the concentration of the petroleum hydrocarbon of surface sediment in Liaodong Bay from 2015 to 2017 was in the range of 1.5×10−6~2790.0×10−6, with a median value of 62.7×10−6. The total median values of petroleum hydrocarbon of surface sediment of marine functional zones in Liaodong Bay (the top three) were: Port shipping area>Reserve area> Agricultural and fishery areas while the sequence of total over standard rate of petroleum hydrocarbon in sediment stations of marine functional zones in Liaodong Bay (the top four) was Industrial and urban sea area> Reserve area>Agricultural and fishery areas> Port shipping area from 2015 to 2017. The results indicate that the petroleum hydrocarbon mainly comes from areas with more frequent production activities, such as port and maritime areas, coastal areas for industrial and urban use, reservation areas, agricultural and fishery areas, etc.

Abstract:
Under the background of the marine economic powerful nation strategy, the development of islands is restricted by their special natural conditions, which is relatively backward compared with their neighboring land. Most China's islands are scattered in different areas, and play a role as an important " bridgehead” in the process of human discovering the ocean, therefore, the coastal provinces and cities have been always seriously concerning about the development of islands. The evaluation model of island group is constructed with the evaluation index that considering four aspects: resource supply capacity, ecological environment carrying capacity, economic development capacity, and the social support capacity of the island group. The Changdao island group, Nanao island group, and Weizhou island group are selected to conduct the development evaluation, according to their location, connectivity with land, climate type, and availability of data. The evaluation results of above island groups are compared and analyzed. The evaluation results indicate the development of Changdao island group is superior to the Nanao and Weizhou island groups. Referring the analysis, the infrastructure conditions, the tourism development stage, the effective protection of ecological environment, and the attention from local government are the major factors of determining the development of island area.

Abstract:
Marine sediments are not only the reservoir of pollutants, but also the source of overlying water. There are high bacterial richness and diversity in marine sediments, and the heterogeneity of sediments lead to bacterial community of oil spill response diversely. The structure and diversity of bacterial communities can reflect the degree of oil pollution and the level of biodegradation to a certain extent, and there is a relationship between the relative abundance of hydrocarbon degradation genes and the level of pollution. In this paper, the diversity of bacterial communities in marine sediments after oil spill was reviewed, and the variation of bacterial communities in the supratidal zone, intertidal zone, subtidal zone and deep-sea sediments after oil spill was emphatically analyzed.

[Abstract](423) [FullText HTML](241) [PDF 1215KB](3)
Abstract:
In order to understand the impact of human activities on the changes of wetland landscape types in the Yellow River Delta wetland and to identify the dominant human factors, this paper uses Landsat 1976, 1986, 1996, 2006, 2016 satellite data and uses landscape transfer matrix, and human activity intensity model to quantitatively monitor the wetland landscape types under the influence of human activities in the Yellow River Delta during the 40 years and assess the impact of human activities by partitioning in the study area. The results are as follows: (1) Three kinds of conversions that are greatly affected by human disturbance: natural wetlands to human-made wetlands and non-wetlands are the most, and non-wetlands to human-made wetlands are medium, and human-made wetlands to non-wetlands are the least. (2) The proportion of landscape types that have been affected by human disturbances in the study area has been increasing, and the impact rate of human activities has increased from 16.77% in the first 10 years to 52.94% in the last 10 years. Farmland farming was the main human activity factor affecting the change of landscape types from 1976 to 2006. Between 2006 and 2016, the distribution of changes in natural wetlands area affected by various human activities is relatively balanced, and the proportion of transfer to reservoirs ponds is 34%. Farmland reclamation was the main influence in 1976-2016. (3) The human activity intensity model is applicable to the calculation of human activity intensity in the Yellow River Delta wetland. Between 1976 and 2016, severe disturbances were mainly concentrated in coastal areas, undisturbed and interference weakening areas were mainly concentrated in nature reserves. The results are in good agreement with the actual field survey results. The results of the study can provide a useful reference for the relevant departments to protect, manage and rehabilitate wetlands in the Yellow River Delta.

Abstract:
In the process of implementing adaptive management, management performance evaluation is an important step of adaptive management evaluation. According to the "pressure-state-response" idea, 33 indicators are selected to construct the adaptive management performance measurement model of marine eco-economic system. The results of a case study of Shandong province show that the adaptability management level of the marine eco-economic system has been obviously improved in the province from 2006 to 2015, but the adaptive management degree of the three sub-items of pressure, state and response and their changing trends are obviously different. The results of the obstacle diagnosis show that the factors that affect the performance improvement of the marine eco-economic system mainly come from the pressure layer, namely the interference of the exogenous factors to the marine ecological environment can’t be ignored. In order to realize the sustainable development of the marine eco-economic system, we must continuously improve the adaptive management system of the marine eco-economic system, continue to innovate adaptive management system, guide all stakeholders to strengthen adaptive learning, continuously increase various inputs and improve the level of adaptive management under the leadership of the government.

Abstract:
Community structure of zooplankton in the Yellow Sea was characterized based on the samples collected with a WP-2 plankton net (200-μm mesh) in May, 2012. Species composition, abundance, dominant species of zooplankton were analyzed together with the environmental data. A total of 65 zooplankton species and 27 larvae taxa were identified in the study area. The mean abundance of zooplankton (excluding Noctiluca scintillans) is 8109.5±7585.0 ind/m3, which was higher than that of zooplankton collected with coarse-meshed net (505-μm mesh). The dominant species consisted mainly of the small zooplankton, including N. scintilllans, Oithona similis, Centropages abdominalis, Paracalanus parvus, Acartia clausi, Calanus sinicus and copepod nauplii. CLUSTER analyses grouped the zooplankton in the study area into 4 communities, including the East China Sea inshore mixed water community, the neritic community, the Yellow Sea central community and the North Yellow Sea community. The clustering was in concert with the result of previous results.

Abstract:
Coastal line is not only the space carrier of marine economic development in coastal areas, but also an important platform to protect the marine environment and maintain the ecological balance of coastal zone. Generally speaking, it can be divided into natural shoreline and artificial shoreline. Since the 1990s, with the rapid economic and social development of China's coastal areas, the intensity of offshore sea area and coastline development has been increasing. By 2018, the proportion of artificial coastline in China has exceeded 75%, and that of individual provinces and cities has exceeded 90%. Overload development and utilization of the coastline has brought about environmental problems, and also caused difficulties in the protection and management of the coastline. It is suggested that work should be carried out from the perspectives of establishing coastline management system, establishing responsibility supervision mechanism of natural coastline retention rate, implementing coastline rehabilitation and implementing coastline supervision and management and so on, so as to promote the protection and utilization of coastline resources in China in the new era.

Abstract:
The effects of petroleum hydrocarbons on ingestion and metabolism of Calanus sinicus were studied. The results showed that petroleum hydrocarbons had significant effects on filtering rate, ingestion rate, respiratory rate and ammonium excretion rate of C. sinicus (p<0.05). Ammonium excretion rate was significantly different from every concentration groups (p<0.05), which was the most sensitive to the changes of petroleum hydrocarbon concentration. There were no significant differences in filtering rate, ingestion rate, respiratory rate and ammonium excretion rate between 0.051 mg/L, 0.103 mg/L, 0.215 mg/L concentration groups and the control group (p>0.05) after 14 days of recovering culture. The filtering rate and ingestion rate of 0.43 mg/L and 0.86 mg/L concentration groups were significantly differences from the control group (p<0.05), and no significant differences in respiratory rate and ammonium excretion rate (p>0.05). In the control group and low concentration groups, protein metabolism was dominant metabolism styles, the O:N ratio increased when exposed to 0.43 mg/L and 0.86 mg/L concentration groups, carbohydrates or fats began to participate in metabolism. After 14 days of recovering culture, the metabolic was still based on protein in all concentration groups.

Abstract:
This paper introduces the application of compensation method for ecological loss caused by Marine engineering construction from two aspects: financial compensation and ecological restoration compensation. Two methods of ecological loss compensation fund accounting are discussed in the part of financial compensation, based on the ecosystem service function and based on the ecological restoration respectively. Ecological restoration compensation mainly introduces two different ways: the in situ ecological restoration compensation of structural forms with ecological effects from the engineering structure itself, and the heterotopic ecological restoration compensation of constructing new habitats in other places for ecological reconstruction. Last the compensation scale of different marine engineering is estimated based on HEA.

Abstract:
Nuclear power industry developed rapidly in China in recent years and the environmental problems that followed have attracted much attention. In this study, three kinds of data source, MODIS thermal data, HJ-1B infrared scanner data and Landsat-8 thermal infrared data, which were imaged at simultaneous phase and different spatial resolution, were used to calculate sea surface temperature in the waters near the Hongyanhe nuclear power plant. Based on the corrected gulf average temperature method, the thermal plume distribution of nuclear power plants with three kinds of data source was obtained. Analysis shows that: Landsat-8 data achieves the highest accuracy and more details in thermal plume distribution. For restriction of the "mixed pixel" effect caused by low spatial resolution, HJ-1B and MODIS data have a bad performance. According to the differences in hydrogeological conditions between different monitoring areas, it’s wise to use satellite data with different time phase and spatial resolution Comprehensively. It can be foreseen that unmanned aerial vehicles with infrared payload is expected to be a powerful complement to satellite remote sensing monitoring methods.

Abstract:
Radium isotopes were important tracers for water transport and mixing processes. We investigated the distribution of 226Ra and 228Ra in the northern slope of the South China Sea (SCS) during spring based on a cruise conducted in March 2017. The results proved that the activities of 226Ra in surface water varied from 6.4 to 10.7 dpm/100 L, and those of 228Ra varied from 4.6 to 26.0 dpm/100 L. The 226Ra and 228Ra activities, temperature and salinity in the surface seawater reflected that the surface water in the northern SCS was mainly composed of two water masses, namely the SCS water and the Kuroshio branch water. The proportion ranges of the two water masses in study area was 0.13~1.05 and 0.87~−0.05, respectively. The activity ranges of 226Ra and 228Ra in sea water column were 5.9~29.7 dpm/100 L and 2.6~6.5 dpm/100 L. Using a steady-state hypothesis and the two-box model of 226Ra and 228Ra, the residence time of seawater below 1500 m in the northern SCS was estimated to be approximately 14~61 years.

Abstract:
Beaches are an important support for the development of coastal tourism and recreational fisheries. Beach quality evaluation is an important basis for the protection and rational development and utilization of beaches. Based on the characteristics of the resources environment of Dapeng peninsula beaches in Shenzhen, a suitable quality evaluation system was constructed for Dapeng peninsula referred to main domestic and overseas quality evaluation systems of beaches. The quality evaluation system covers three elements: nature, society and humanity. To be specific, this system consists of 2 aspects, 5 categories, 9 sub-categories and 33 factors that reflected the characteristics and functions of the beaches. Analytic hierarchy process (AHP) was applied to determining the indicators weight. There are five grades given by the beach quality evaluation system which were excellent beaches (≥80), good beaches (70~80), passing beaches (60~70), medium beaches (50~60) and poor beaches (<50). The results showed that the average score of beaches quality was 68.62 in resources and environment. The quality of most beaches resources and environment was pass level. The average score of beaches tourism service quality was 46.88. The quality of beaches tourism service was poor. The quality was evaluated as 3 excellent beaches, 11 good beaches, 15 passing beaches, 20 medium beaches and 4 poor beaches. The comprehensive quality evaluation level of the beach was passing. According to the evaluation of beaches quality, beaches development and management suggestion was proposed.

Abstract:
Improving the economic efficiency of marine space resource utilization is an important measure for building marine power. This paper proposed a marine industry classification system, then constructed some mathematical models for study on the relationship between sea structure and economic value of marine industry, such as the industrial sea structure diversification index, economic output value and economic efficiency, and analyzes the relationship between the spatial resource use structure and economic efficiency. The conclusions were as follows: (1) The marine industry classification system had an important practical significance for other related research; (2) China's marine industry sea uses were mainly in traditional marine industries, such as fishery, transportation, engineering and construction, which distributed centrally in space; (3) The sea structure diversification index of China's marine industry was generally low, and the inter-provincial difference of ocean space resource use economic output value was obvious; (4) The economic efficiency of marine space resource use was basically positively correlated with the diversification index.

Abstract:
To better understand the distribution of environmental factors and the response of phytoplankton in the Laizhou bay, a comprehensive survey contained 31 stations about surfer sea temperature (SSS), surfer sea salinity (SST), nitrite (NO2-N), nitrate (NO3-N), ammonium (NH4-N), dissolved inorganic nitrogen (DIN), phosphate (PO4-P), silicate (SiO3-Si) and net-phytoplankton abundance and species diversity (H′) was conducted in August 2017. In the present study, obvious spatial distribution differences of environmental factors were observed with high SST, nutrients while low SSS located in southwest coast of the Laizhou Bay, especially at Xiaoqing River estuary. The terrestrial inputs such as the Xiaoqing River and its vicinity were the main factors influencing the distributions of SSS and nutrients. The low NH4-N value at the Xiaoqing River estuary was mainly attributed to the NH4-N reduction in the Xiaoqing River. High phytoplankton abundance and low H′, showing obvious spatial distribution differences, were mainly observed at the Xiaoqing River estuary. Four different phytoplankton groups were observed according to the community structures difference indicating an obvious response of phytoplankton to environmental factor variations. Phytoplankton abundance showed significant negative correlation with SSS and Si/N (p<0.05) while positive with NO3-N, NH4-N and DIN. Significant negative correlations were observed between H′ and SST, DIN (p<0.05). The phytoplankton community structure were mostly influenced by the environmental combination of NO3-N、NH4-N、DISi、Si/N and single factor of DISi.

Abstract:
In this thesis, a method for the determination of major elements (including Na2O, MgO, Al2O3, SiO2, P2O5, K2O, CaO, Fe2O3, MnO, and Ti2O) in marine sediments by the X-ray fluorescence (XRF) spectrometry is optimized. In the experiment, the Li2B4O7-LiBO2 mixture [m(Li2B4O7):(LiBO2)=67:33] is adopted as the flux, LiNO3 as the oxidant, and LiBr as the mold discharging agent. Under the above condition, the sample was prepared by melting. Meanwhile, the calibration curves were constructed, through applying the certified reference materials, such as soil, stream sediment, and marine sediment by X-ray fluorescence spectrometer. Moreover, the effects of flux, dilution ratio, remolding agent, melting temperature, and melting time on the determination results, were systematically studied. The results show that high-quality fuses were obtained under the following conditions: the sample and the mixed flux was uniformly mixed; the melt dilution ratio is 1:10; the mixture was pre-oxidized at 700 °C for 200 seconds and melted at 1,050 °C for 10 minutes. The loss on ignition (LOI) detection was not necessary while a relative large dilution ratio combined unknown LOI correction was adopted, which greatly simplified the test method. Testing with the marine sediment standard substance GBW07314, we find that the relative standard deviation (RSD) of each component content was 0.32%~2.05%, and the detection limit of the method was 70~270 ug/g. In the accuracy of the artificial standard sample, there was no significant difference between the measured value and the recommended value. The results reveal that the method is accurate and reliable, which can be utilized for accurate quantitative analysis of geological and geographic stream sediments, rocks, minerals, soils, and other samples., rocks, minerals, soils, and other samples.

Abstract:
The bioturbation effects of Sinonovacula constricta on the transformation of different forms of nitrogen in sediments were studied based on a laboratory experiment in this study. Two treatment groups and a control group were set up according to different biological densities (99 ind/m2, 249 ind/m2), and a 20-day laboratory experiment was carried out in the condition of water temperature 23℃, salinity 26 psu, and pH8. The columnar sediments were stratified and cut from top to bottom, and the changes of different forms of nitrogen content in the sediment were analyzed. Results showed that the content of total nitrogen (TN) in the sediment increased after the bioturbation of S. constricta. The content of non-transferable total nitrogen (NTN) increased by 30.94%, and the content of transferable total nitrogen (TTN) decreased by 20.57%. The content of organic-sulphide form (OSF-N) was the highest among the four forms, accounting for 9.31% of TN, which was the main form of TTN. The content of carbonate form (CF-N) was the lowest and only 2.77% of TN. The ion exchange form (IEF-N) and the iron manganese oxide form (IMOF-N) accounted for 3.39% and 3.06% of TN, respectively. Above all, the bioturbation of S. constricta promoted the conversion of OSF-N to other forms, as well as the conversion of transferable total nitrogen to non-transferable total nitrogen.

Abstract:
Based on historical records of red tides from 1952 to 2017, and according to the analysis of their temporal, spatial, and biological variation, the basic characteristics of red tides in Shandong coastal waters are studied with preventive countermeasures proposed. Non-toxic dinoflagellate blooms are frequently observed with a scale less than 10 km2 in shandong coast waters. The incidence of red tides is high from May to September and most events occur in the Yellow River Estuary, midwest of Laizhou Bay, Changdao offshore waters, Sishili Bay, Donggang offshore waters, Jiaozhou Bay and the Qingdao coast. Compared with other species, Noctiluca scintillans is frequently found. However, new causative organisms have been identified and the proportion of toxic and biphasic red tides has also increased since 2000. In order to prevent red tides, the level of information monitoring should be improved, risk assessments carried out and comprehensive management of the marine environment promoted.

Abstract:
As the last ‘pure land’ in the world, the Antarctic attracts many countries’ interest because of rich natural resources as well as inherent scientific and aesthetic values. Under the influence of factors such as global warming and human activities (scientific research, commercial fishing, tourism, etc.), the Antarctic ecological environment problems such as regional increase/decrease of Antarctic sea ice area; fluctuation of Antarctic species; and aggravating of environment pollutants detected are emerging. However, the current management policies based on the "Antarctic Treaty System" cannot fully regulate human activities due to issues such as abstraction of ideas. The environmental protection in Antarctic is becoming increasingly severe. International community should develop interdisciplinary international collaboration, strengthen the link between scientific research and management and improve management policies of Antarctic ecological environment so as to minimize the destruction on the Antarctic ecological environment.

Abstract:
The transparent exopolymer particles(TEP), a kind of transparent colloidal particulate matter, consists of extracellular polysaccharides. TEP is of great significance to the carbon cycle of marine ecosystems. In this study, two marine diatoms, Ditylume brightwelii and Chaetoceros affinis, were studied. The TEP concentration, the relationship between TEP and Chlorophyll a (Chl a) and the C∶N ratio of TEP were studied at different growth phases. The results showed that TEP was produced by both species during the whole growth phases, and TEP concentration was different in different growth phase. The maximum TEP concentration of D. brightwelii and C. affinis was produced in the exponential phase and the decline phase, respectively. The maximum TEP concentration per cell volume and per Chl a of C. affinis was 184.91±14.03 fg Xeq/μm3 and 38.06±4.96 μg Xeq./μg Chl a, and were 16 and 5 times higher than the values obtained from the D. brightwelii. The analysis of the relationship between Chl a and TEP in two diatoms showed that the function relationship between TEP=α (Chl a) β was presented in the exponential phase (D. brightwelii: R2=0.98; C. affinis: R2=0.80). The TEP C∶N ratio of both diatoms was higher than the Redfield ratio (C∶N=106∶16). It indicates that the generation of TEP was difference between species, and the growth phase significantly affects the efficiency of TEP production. The high carbon concentration of TEP show that TEP production contributes significantly to the ocean carbon cycle.

Abstract:
Export fluxes of sinking particulate organic carbon (POC) are important for the function of biological carbon pump. Vertical transportation of POC into the ocean interior can be affected by particle-attached bacteria (PAB) via the change of their abundance and activities, which may eventually affect the carbon sequestration into the ocean. In order to better understand the characteristics of PAB in the turbid nearshore waters along the Pearl River Estuary (PRE), we applied and modified an existing analytical procedure to effectively detach PAB from sinking particles for more direct and accurate estimation of PAB. The coupling relationship between environmental factors and the abundance of PAB were further analyzed and discussed. our results suggested that PAB from the fraction 2~20 μm particles was the dominant component of PAB in all stations. Moreover, there was a spatial change of PAB along the PRE with the highest abundance at Xiangzhou port (4.21×109 cells/L), following by Zhongda port (1.13×109 cells/L) and Wanshan island (0.27×109 cells/L). We also found that suspended organic particles might have supported PAB growth at Xiangzhou port where there was high PAB but low chlorophyll a. In addition, the growth of PAB might also subject to influences by varying concentrations and species compositions of inorganic nutrients in coastal waters. These results may be important for further understanding of PAB associated biogeochemical processes in coastal ecosystem.

Abstract:
A sediment core was collected in the Jiaozhou bay in 2011. The concentrations of eight heavy metals (mercury (Hg), arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn)) in the sediment core from 0 m to 1 m were measured. These raw data were then utilized to calculate the enrichment factors (enrichment factors, EFs, represents the enrichment status of elements) of these metals. The results showed that both concentrations and EFs of these heavy metals presented a peak or had the highest value in the subsurface layer (at around 20 cm) of the sediment core. The age of sediment at such depth was estimated to be around 20 years using the reported sediment settlement rate. This indicates that the contamination of heavy metals in Jiaozhou bay sediment may be significantly affected by the high-intensity anthropogenic discharge of heavy metals into the Jiaozhou bay in the late 1980s and 1990s. Pearson correlation and multiple regression analyses were further performed to investigate the primary controlling factors for heavy metals in Jiaozhou bay sediment. The results suggest that the inter-annual variations of the eight common heavy metals may be controlled by different environmental factors in Jiaozhou bay sediment. In addition, the potential ecological risk index was calculated to evaluate the potential risks of these heavy metals in Jiaozhou Bay sediment and their historical variation trends. Mercury generally had a moderate risk in the Jiaozhou bay, and its risk has been increasing in recent years. This finding suggests that Hg should be put in the priority metal to be controlled in the Jiaozhou bay.

Abstract:
The total 21 surface sediment samples were collected in the sea area around Liandao island, which is located in Haizhou bay, Jiangsu province, China. The heavy metals (Cd, Cr, Cu, Pb and Hg) contents and the metal-like arsenic (As) content were determined. The spatial distribution maps of heavy metals and metal-like As were obtained by using Kriging interpolation method. The pollution degree and risk grade of heavy metals and metal-like As were assessed by ground accumulation index and potential ecological risk index respectively. The results were indicated that the average content of heavy metal Cu was higher than the Class 1 standard according to the Marine Sediment Quality (GB 18668-2002). The variation coefficients of heavy metal Cu and Pb were 114.66% and 108.44% respectively. Therefore, they had strong spatial dispersion. The pollution degree of heavy metals and metal-like As ranked from large to small: Cd>Pb>Cu>As>Hg>Cr based on the analysis results of ground accumulation method, in which heavy metal Cd, Cu and Pb were the moderate pollution, As and Hg were mild pollution, and Cr was non-pollution. The overall potential ecological risk level in the sea area of Liandao island reached the medium level. There existed the high ecological risk level of heavy metals and metal-like As in the southern part of Liandao island. Further, the ecological risk of surface sediments was mainly caused by heavy metal Cd.

Abstract:
Dissolved gaseous mercury (DGM), reactive Hg (RHg), total Hg (THg) and dissolved Hg (DHg) concentrations were analyzed in the seawater of the East China Sea (ECS) during a cruise in June 2018. The distribution patterns of DGM and RHg and their controlling factors in the East China Sea (ECS) were investigated. The concentrations of DGM and RHg in the seawater were determined to be 151.3±75.9 pg/L and 0.8±0.7 ng/L, respectively. The ratios of DGM/THg, DGM/RHg and RHg/THg were calculated to be (4.5±2.5)%, (26.7±15.0)% and(21.6±14.8)%, respectively. DGM and RHg concentrations in the ECS water were significantly higher than that in most open oceans, but lower than or comparable to that reported in most coastal seas. Both DGM and RHg in the seawater presented a complicated spatial distribution pattern, with high concentration areas located in both nearshore shallow seawater, and offshore shallow and deep seawater. These results indicate that both species of Hg may be controlled by both the terrestrial input and in situ production/removal processes. As for the vertical distribution, the concentrations of DGM and RHg in the bottom seawater were observed to be the lowest, while comparable concentrations were observed at all the other sampling layers. Although highest THg concentration was observed in the bottom seawater of the ECS, DHg concentrations in the bottom seawater were slightly lower than those at the other layers. This may be a reasonable explanation of the lower RHg and DGM concentrations in the bottom water. Spearman’ correlation and multiple regression analyses suggest that RHg and dissolved oxygen (DO) concentrations may be the major controlling factors for DGM in the seawater, while RHg in the seawater may be controlled by DO.

Abstract:
The study interpreted seven temporal satellite remote sensing images of Zhoushan Petrochemical Base project area, Combined the collection of relevant information and the field survey of landing on the island, extracted and analyzed the changes of coastline and vegetation distribution in different periods of Zhoushan petrochemical base construction through remote sensing (RS) and geographic information system (GIS). The results show that natural shoreline of island group reduced by 21.335 km in Zhoushan Petrochemical Base Project which accounts for 75.4% of the original natural coastline. Vegetation of island group reduced by 3.537 km2 which accounts for 74.0% of the vegetation area of the original island group in the past three years. The change of island group can be divided into four stages: the development of main island Dayushan, the process of connecting Dayushan Island and Xiaoyushan Island, the island group enclosed as a whole and enclosure period of island group expansion. In the first three stages, the natural shoreline of island group decreased rapidly, the artificial shoreline increased rapidly. In the fourth stage, the natural shoreline decreased slowly, and the artificial shoreline rushed up and fell back quickly. The vegetation of the island group decreased rapidly in the first two stages and slowly in the latter two stages. The above characteristics are mainly related to the process of the project construction. It is suggested that the island management department should do a good job in ecological protection and restoration in the development of the island group because of the serious influence to the original ecological environment of the island group created by the project development.

Abstract:
In order to study the distribution of polycyclic aromatic hydrocarbons (PAHs) in the sediment-seawater system, 16 kinds priority control PAHs in the sediments and seawater from 9 sampling points at the Xiangshan port were analyzed in January 2017. The source analysis and diffusion equilibrium were conducted by isomerism ratio method and fugacity approach. The concentrations of PAHs in the sediments ranged from 17.51×10-9~84.41×10-9, mainly high ring PAHs, and the pollution level was minor polluted. The PAHs in the sediments primarily came from high temperature combustion sources. The ranges of PAHs in the surface seawater, intermediate seawater and bottom seawater were 41.78~105.72 ng/L, 41.51~106.34 ng/L and 9.18~145.17 ng/L, respectively, which low ring PAHs were the most abundant compounds. The sources of PAHs in seawater originated mainly from oil leakage and oil combustion. The fugacity fraction was calculated to judge the diffusion behavior of PAHs. Nap, Ace and Flo were released from sediments to seawater. Acy, Phe, Ant and Pyr were close to the dynamic equilibrium in sediments and seawater. Flu, BaA, Chr and BbF were mainly diffused from seawater to sediment.

The sea surface temperature has been retrieved from Landsat 8 TIRS 10, which shows that the water temperature nearby the discharge area of Nanpu power plant are increased in summer and winter compared with that in the reference area. The scope of water temperature rise is larger and the degree is smaller in summer, while the scope of water temperature rise is smaller and the degree is larger in winter. The thermal discharge pollution from the power plant goes northwest to Waiwu island at rising tide, and moves to southeast at ebb tide. Due to the coal wharf and diversion dike, thermal discharge has little effect on intake. The retrieving results based on satellite images are consistent with the numerical simulation results before project construction.

Abstract:
Archaeal community plays an extremely important role in marine biosphere and affects the cycling of carbon, nitrogen, sulfur, iron, and other elements in marine ecosystems. There are a large number of archaea in marine sediments. The investigation on their distribution and diversity lays the basis of understanding their ecological functions. In this study, the sediments of Jiaojiang Chemical Industry Park of Zhejiang Province were sampled, and metagenomic analysis based on the Illumina Miseq PE300 high throughput sequencing platform was applied to investigate the Archaea community. A total of 52 genera, 37 families, and 11 phyla of Archaea were detected from the sediments. Thaumarchaeota was the most predominant phylum, accounting for 49% of the total abundance, followed by Crenarchaeota, Euryarchaeota, and Woesearchaeota. Nitrosopumilus was the most abundant group at genus level, accounting for 48% of the total abundance. Obvious spatial heterogeneity was found in marine sedimental environment in the study area, which might have an impact on the archaeal community structure. Cadmium, lead, arsenic, chromium, mercury and other heavy metals were significantly correlated with certain archaeal phyla.

Abstract:
In this study, 11 organophosphorus esters (OPEs) in the surface water from mariculture farms, estuaries and the nearshore of the Qinzhou bay were analyzed. The total concentration of 11 OPEs averaged 126 ng/L and ranged from 32.9 to 227 ng/L the mean, which was at the lower level among the similar regions worldwide. The predominant contaminants were TCEP, TCPP and TBEP. The level of individual OPEs in the Qinzhou bay was mainly affected by their own aqueous solubilities and octanol-water partition coefficients (KOW) as well as their productions and consumptions. In general, the concentrations of OPEs were higher in the aquaculture ponds than in the nearby estuaries and nearshore area. The OPEs accumulated in the ponds might be mainly from the sources of culture water: rivers and coastal water. Chlorinated OPEs were more persistent than non-chlorinated OPEs in the culture ponds. So far, the concentrations of OPEs in the study area have no significant ecological impact on the surrounding environment, but its potential threat to human cannot be ignored because of their possible bioaccumulation in seafood.

Abstract:
The sources of microplastics in coastal areas are complex. The fragmentation of large plastics through physical, chemical and biological processes is one of the main sources of microplastics in the beaches. This study investigated the compositions, abundances, shapes, colors and components of plastic debris and the microplastics of different sizes in 7 beaches in Sanggou bay of the Yellow Sea. We also studied the relationships between the fragmentation of plastic debris and microplastics by qualitative and quantitative analysis, which can be used to identify the sources of the microplastics. The results showed that polystyrene foam accounted for 85%, 97% and 82% of the samples in the size range of 5 mm ~ 2.5 cm, 1 ~ 5 mm and <1 mm respectively. In plastic debris >2.5 cm, the types of the plastic debris related to mariculture accounted for 76%. The total abundances of plastic debris and microplastics increased by 2 ~ 4 orders of magnitude with the decrease of sizes and the abundances of microplastics and plastic debris in 1 ~ 5 mm and 5 mm ~ 2.5 cm were significantly correlated. By comparing the morphology and components characteristics of different sizes of plastic debris and microplastics, the sources of microplastics were identified as fragmentations from polystyrene foam, polyethylene float, yellow sponge, fiber fishing ropes and polypropylene film ropes. The results indicate that mariculture is one of the important sources of plastic debris and microplastics in beaches of Sangou bay. In the future, it is necessary to further explore the identification methods of sources and find new evidences to identify the sources of microplastics.

Abstract:
Full polarization interferometric radiometer, which can image from interferometric synthetic aperture and get full polarization information, is the new type of microwave radiometer that can measure various physical information of ocean with high resolution and low consumption. By introducing the development of full polarization and synthetic aperture respectively, we expound on the necessity and principle of full polarization and synthetic aperture to aquire ocean information. Taking the advantages and disadvantages of WindSat and MIRAS as an example, we have discussed the advantages of multi-functional microwave radiometer and multi-load microwave sensors satellite to observe ocean. Moreover, to develop our satellite observation of ocean salinity, the necessity and the difficulity of collaborations of full polarization interferometric radiometer are pointed out for the application of multiple microwave remote sensing.

Abstract:
Timely pretreatment and proper storage of nutrient samples are the pre-conditions to ensure the reliability of data. In this study, we examine the differences between frozen storage and preservation with mercury chloride at room temperature for dissolved silicate in the Yellow River water sample that is characterized of high turbidity. We found out that there was no significant difference between the two storage methods. We compared in-situ filtration (freezing stored in 9 mL vacuum polyethylene terephthalate tube) and delayed filtration (freezing stored in 125 mL high density polyethylene bottle) for the nutrients, and discussed the effects of delayed filtration time on nutrients data quality. Nitrite, nitrate and phosphate were not affected by prolonged filtration time, while ammonium was significantly impacted by a decrease of 11%~46%, possibly due to suspended particulate matter adsorption and/or phytoplankton assimilation. As for silicate, storage container and its volume may play a major role in silicate storage while the prolongation of filtration time is much less important.

Abstract:
Submarine groundwater discharge(SGD) has been recognized as an important pathway for nutrients into ocean and plays an important role in global water cycle.In this study, seawater and groundwater samples were collected from the coast of Shengsi Island, Zhejiang Province and radium isotopes (223Ra, 224 Ra, 228 Ra) and nutrients were analyzed in the lab.Then SGD and its derived nutrients fluxes were estimated.The results showed that Radium activities in groundwater (223Ra:16.7 ±2.9 dpm/100 L, 224Ra:479 ±18 dpm/100 L, 228Ra:97 ±4 dpm/100 L) were much higher than those in seawater (223Ra:3.5 ±0.7 dpm/100 L, 224Ra:80 ±4 dpm/100 L, 228Ra:31±2 dpm/100 L).Moreover, the tidal-drived SGD rate were calculated to be 7.6 and 4.1 cm/d based on 223Ra and 224Ra, respectively.However, according to the decay of 223Ra with distance offshore, a SGD flux of 22 cm/d was derived.Based on SGD flux, the flux of dissolved inorganic nitrogen (DIN), dissolved inorganic phosphorous (DIP) and dissolved silicon (DSi) were calculated to be 593, 4.16 and 241 μmol/(m2·s), respectively.

Abstract:
Phytoplankton net samples were collected in the south sector of Eastern Indian Ocean (10.0°S-4.0°N, 83.0°E-97.5°E) from March 13 to May 7, 2013.Phytoplankton community structure features were analyzed, including species composition, ecotypes, cell abundance, dominant species, and diversity.To understand the inter-annual variation of phytoplankton community under the context of climate change, we also compiled previous phytoplankton community data in the 1960s and 2013, and compared with present study.Of the 350 taxa (including variation, form and unidentified taxa), 162 taxa of 48 genera in Bacillariophyta, 183 taxa of 24 genera in Dinophyta and 4 taxa of 2 genera in Chrysophyta were recorded.The dominant phytoplankton ecotypes were tropical oceanic species and warm oceanic species.The dominant species were mostly Bacillariophyta, such as Planktoniella formoa, Nitschia spp.Chaetoceros spp., Climacodium frauenfeldianum and Pseudosolenia calcaravis, while the others belonged to Dinophyta (Pyrocystis noctiluca and Neoceratium trichoceors).The highest cell abundance of 140.3×103 cells/m3 were recorded in the southeast of surveyed area, and intermediate level of 104 cells/m3 were found around the equator.In the last 60 years, the taxa number of phytoplankton community, including both Bacillariphyta and Dinophyta, increased.Dinophyta had higher species number than Bacillariophyta.However, Bacillariophyta always dominated phytoplankton community in the Eastern Indian Ocean, and the number of dominant species belonging to Chaetoceros spp. increased remarkably in the last several decades.

Abstract:
Planktonic ciliates, which play important roles in transferring materials in food webs by grazing on primary producers, are considered as an important group of protozoans in coastal waters.Diatoms are important primary producers dominating phytoplankton community in coastal ecosystem.To better understand the role of ciliates in the transmission of primary producers (especially diatoms) along the food chain, two dominant species of tintinnids (Tintinnopsis tocantinensis and T.schotti) were collected from coastal water of Sanya bay in April, 2015, and in situ feeding diversity of these ciliates were analyzed by molecular techniques.In total, 13 diatom species belonging to 8 genera were detected in the diet of ciliates, including Skeletonema, Leptocylindrus, Rhizosolenia, Thalassosira, Pseudo-nitzschia, Cymatosira, Asterionellopsis and Chaetoceros. Two species of ciliates had the same preys as Skeletonema, Leptocylindrus, Rhizosolenia and Thalassosira, among which Skeletonema (S.costatum) was the most abundant prey items (>60%, percent of total squences).T.schotti, a larger size species, had a more diverse diet (11 species) than that in the smaller T.tocantinensis (7 species).Furthermore, the most abundant phytoplankton species (Pseudo-nitzschia) in the ambient water (49.12%, percent of phytoplankton abundance) was only detected in T.schotti(15.55%, percent of total sequences), which suggested ciliates have a selective feeding behavior in the natural environment.The results directly proved that ciliates could widely feed on diatoms and indicated that ciliates were an important link of diatom transfer along food chain in coastal ecosystem.These findings are helpful to understand the ecological role of ciliates and materials transfer in coastal ecosystems.

Abstract:
Based on four surveys carried out during 2016 and 2017, weanalyzed the distribution and variation of resources of Sargassum thunbergii with random sampling method in three regions of Dalian, Qingdao and Wenzhou, China.The results showed that the morphology and biochemical composition of Sargassum thunbergii had obvious regional differences and time variations.The number of size distribution of Dalian was much more than Qingdao and Wenzhou.In October, the biomass of Qingdao(429 g/m2)was the largest in three regions.The biomass of Dalian in October, February and May were 931.3 g/m2, 1453.1 g/m2 and 2047.7 g/m2, respectively. And, the number of primary branches of Qingdao were the largest in October, February and May, which were 4572/m2, 5707/m2, 3659/m2.But, it appeared the lowest number(2199/m2) in July.Lateral branches were first found in Dalian, and the percentages of lateral branches withing lateral branches in three regions were highest in July.The number of lateral branches in Dalian was the highest (123±63/plant) and the longest (13.1 cm).The contents of Chlorophyll were higher in Dalian than others.However, the contents of phlorotannin of Qingdao and Wenzhou were higher than Dalian.The highest contents of phlorotannins appeared in May in Dalian and Wenzhou while it appeared in July in Qingdao.The results of our investigation showed that the population structure and morphological characteristics of Sargassum thunbergii were significantly different between regions and times, which may depended on anthropogenic and environmental factors.

Abstract:
Concentrations of monosaccharides (MCHO), polysaccharides (PCHO) and total dissolved carbohydrates (TCHO) were measured with 2, 4, 6-tripyridyl-s-triazine (TPTZ) method in the seawater of the South Yellow Sea and the East China Sea during spring.Our results showed that the concentrations of dissolved carbohydrates in South Yellow Sea were higher than those in the East China Sea.Moreover, distributions of MCHO, PCHO and TCHO at transect B of the South Yellow Sea and transect P of the East China Sea were investigated.The results indicated that the vertical distributions of MCHO, PCHO and TCHO at transect B displayed decreasing trend from inshore to offshore sites as well as from surface seawater to bottom seawater.In contrast, the vertical distributions of MCHO, PCHO and TCHO at transect P did not show similar trend due to the influences of the Changjiang diluted water, Taiwan warm current and Kuroshio.The results of diel variations at station E2 suggested that high peaks of MCHO, PCHO and TCHO appeared from 12:00 to 18:00 and low peaks appeared from 4:00 to 8:00.In addition, TCHO was positively correlated with PCHO, and MCHO had no correlation with PCHO.However, MCHO peaks lagged behind PCHO peaks, which might be because PCHO was decomposed to release MCHO by breaking the glycoside bond.

Abstract:
Seven heavy metals (Cu, Pb, Zn, Cd, Cr, Hg and As) in surface sediments from 26 sites in the northwest waters of Liaodong Bay in autumn of 2013 and spring of 2014 were investigated.The results showed that the concentrations of Hg, Zn and Cd were higher than the background values of Bohai.Marine sediment quality was evaluated with the single factor pollution index method.The results showed that the average value of Hg, Cu, Pb, Zn, Cd, Cr and As conformed to the first-class standard of marine sediment quality.The geo-accumulation index of Hg, Cu, Pb, Zn and Cr were in zero level, and Cd were low.The potential ecological risk of Cd was in middle level and Hg, Cu, Pb, Zn, Cr and As were low.The potential ecological risk of heavy metals was relatively low.Positive correlation was observed between concentrations of 5 heavy metals (Hg, Cu, Cd, Cr and As) and TOC, respectively.Result of principal component analysis showed that the three main sources of heavy metals in marine sediments were industrial wastewater, urban sewage and aquaculture pollution itself, degradation of organic matter and erosion of rocks.This article revealed the distribution of the heavy metals in the northwest of Liaodong bay in order to provide scientific basis for marine sustainable development and marine ecological civilization construction.

Abstract:
With complex spectral characteristics, the Pearl River Estuary sea area belongs to typical Case Ⅱ waters, which has always been a hot area researched by domestic scholars.Based on the apparent spectral data detected from four voyages in Pearl River Estuary in spring (May), summer (August), autumn (November) and winter (February) in 2014, this paper illustrated the types of remote sensing reflectivity and its spatial and temporal distribution characteristics.The results suggest that there are five types of remote sensing reflectivity in the four seasons in Pearl River Estuary, and each type of the spectrum has typical regional and seasonal variation characteristics.The peaks of the spectrum range from 450 nm to 575 nm, with the variation of the seasons, i.e., Type A perennially distributed in Pearl River estuary; Type B distributed in mixed transitional waters outside the Pearl River Estuary in winter and spring; Type C is mainly distributed in the offshore area with deeper depth; Type D distributed in the waters near Wanshan Islands in spring and summer and Type E similar to that of Case Ⅰ waters.The analyses show that the spectral pattern of the five spectral types are dominated by different water quality parameter.The research has shed new light on remote sensing retrieval of color elements and further exploration of the spectral characteristics in our coastal Case Ⅱ waters such as Pearl River Estuary.

Abstract:
UV-Vis spectral data was analyzed for the surface, middle, and bottom layer water samples of the Bohai Sea, Yellow Sea and East China Sea in November and December, 2016.The distribution characteristics, sources and influencing factors of CDOM in the study area had been investigated.The results showed that CDOM concentrations in the Bohai Sea were higher than those in the Yellow Sea and the East China Sea.In these three Chinese marginal seas, the CDOM concentration showed a decreased trend from the nearshore to the open sea.Strong correlations were observed between value a355 and spectra slope S275-295.Considering the distribution patterns of a355 and S275-295, a dominant terrestrial source of CDOM was concluded.In the Bohai Sea, the highest concentration of CDOM was detected in the Yellow River estuary, due to the combining effects of the direct riverine discharge and sediment re-suspension by strong wave movement in winter.The lowest DOC and CDOM concentrations in the Bohai sea were observed in the regions, where the double-center cold-water mass areas occurred in the summer.The invasion of the Taiwan Warm Current, charactered by high salinity and low DOC, resulted in an obvious regional low value of DOC except for CDOM concentration.CDOM and DOC did not show remarkable correlation in the Bohai Sea, Yellow Sea and East China Sea.

Abstract:
Scientific evaluation of the ecosystem services value (ESV) of coastline is an important prerequisite for coastline protection and utilization, which is conducive to identifying the level of coastline protection and utilization and optimizing coastline management.In this paper, the coastline and areas within 1 km of each side of it in Qinzhou, Guangxi was selected as a case study to evaluate ESV of the coastline and explore the application of ESV in the coastline protection and utilization planning.The results indicated that higher ESV are mainly distributed in the northern part of Maowei sea, Seventy-two brook, Sanniang bay and Dafeng river, whereas lower ESV are in the estuary of Qinjiang River, the south part of Jingu River and the south-west part of Dafeng River.ESV can guide and control the protection level and development and utilization value from coastline resources and environment characteristics, and can provide basic support for the coastline protection and utilization planning.The research results can provide reference for coastline planning and management and especially further research.

Sansha Yongle Blue Hole is the deepest marine blue hole for the known ones in the world.Microorganisms play critical roles in this special ecosystem of the marine blue hole.In order to reveal the bacterial role in material cycle of the blue hole, the bacterial community characteristics in sediment from Sansha Yongle Blue Hole was detected using high-throughput barcoded pyrosequencing of 16S rRNA gene.There was a ledge with sediment in about 150 m depth, so the sediment samples were collected from the ledge (152 m and 162 m depth with 10 m distance) and the bottom of the blue hole (about 300 m depth).The bacterial population at three different depth was compared by analyzing sequencing data from Illumina Miseq.A total of 121 690 high-quality partial 16S rDNA sequences were obtained by Miseq sequencing analysis.Those sequences were assigned to 53 phyla, 301 genera and 546 species.The Shannon index at 152 m, 162 m and 300 m were 5.66, 5.72 and 5.55, respectively.Both the dominants and their relative abundance varied significantly at different depth, while some dominants were resemble and overlap.For example, both Chloroflexi and Proteobacteria were dominant phyla among the three samples, but their relative abundance varied significantly:the relative abundance of Chloroflexi was 44.73% at 152 m, 18.42% at 162 m and 4.98% at 300 m, while Proteobacteria was 13.29% at 152 m, 23.00% at 162 m and 44.88% at 300 m.Some bacteria participating in the sulfur cycle were found, such as Chlorobi, Desulfobacteraceae, Desulfatiglans, Desulfococcus, Thiomicrospira and so on, indicating that the sulfur cycle was very active in this marine blue hole.Otherwise the relative abundance of those bacteria was different clearly at the different depth, suggesting the step participating in sulfur cycle varied obviously.

Abstract:
In this study, to solve the question of randomness and uncertainties of traditional evaluation method when taking an assessment of seawater intrusion by using a single index (such as Cl-), an model based on set pair analysis of entropy weight method was built to take an assessment of seawater in Laoshan district of Qingdao city.In this study, Cl-, M, SO42-, γCl-/γHCO3- and SAR was introduced to investigate seawater invasion.The current results indicated that less of the sampling points were influenced by seawater intrusion, the seawater intrusion in Lao Shan area is mainly distributed in the coastal alluvial plain, the downstream of the river and the two sides of the channel.And then compared with the different evaluation methods, the evaluation results are consistent with the single index method and the reality seawater intrusion.So the set pair analysis model based entropy weight method is reasonable and reliable.

Abstract:
The solubility of trace elements in marine aerosols plays an important role in precisely assessing the atmospheric flux and the biogeochemical behavior of trace elements in the ocean.The previous studies showed that there existed significant difference in the solubility of trace elements in the aerosols.In addition to the impact of its own physical and chemical properties and the effect of atmospheric process during its migration, the difference derived from different sampling and extraction methods may be the crucial reason for this phenomenon.This problem is more prominent for the marine aerosol with low trace element content. These systematic errors may not only affect the comparability of previous studies, but also not conducive to the interpretation of data.Therefore, an international science plan, named as "An International Study of Marine Biogeochemical Cycles of Trace Elements and their Isotopes (GEOTRACES)" in 2008 launched marine aerosol international inter-calibration experiments.This article reviews the results from the 2008 GEOTRACES aerosol inter-calibration experiments, compares the samplers, filters, leaching and digestion methods of marine aerosol, and thereby providing suggestions on the most optimized methods of sampling and extracting marine aerosols.

Abstract:
Based on the significantly implication of marine paleo-pH reconstruction to ocean acidification study, different proxies including diatom assemblage, boron isotope composition (δ11B) and B/Ca, brGDGTs and 3-hydroxy fatty acid and their paleo-pH reconstructing methods were summarized in this study.The diatom assemblage, which has been successfully applied with lake sediments, could rebuild oceanic paleo-pH by extract information from the diatoms species and abundance record.Likewise, the δ11B and B/Ca records in marine calcareous organisms were widely used to reconstruct pH in seawater.Both the degree of cyclization or isomerization of brGDGTs and the branching ratio of 3-hydroxy fatty acids could be influenced by the pH level of ambient environment, so the sediment fingerprints of these indicators were used to reconstruct marine paleo-pH.All the approaches have their own merits and demerits, however, δ11B and B/Ca are the most mature indicators for tracing changes of oceanic paleo-pH.Consequently, exploring new methods and improving current techniques are necessary, also of crucial importance for producing more accurate index of oceanic paleo-pH rebuilding.

Abstract:
With the development of information technology, the pace of diversified information systems construction in the marine sector has continued to accelerate.In the context of big data, the heterogeneous nature of ocean data makes it uneasy for ocean data to be shared and managed in a unified way, which leads to the phenomenon of data silos.Combining the MapReduce calculation model, and deeply studying in this issue, this paper proposes a heterogeneous data integration framework based on middleware architecture.The framework adopts the mediator mode for querying data, and uses the graph structure to search for nodes in the query process.Through the practical project experimental verification, the framework can provide an effective real-time data query solution and to a certain extent reduce the occurrence of data islanding.

Abstract:
An estimation method to calculate the pollutant load into sea from point sources (industrial wastewater and domestic wastewater) and non-point sources (agricultural land runoff and livestock industry) for coastal area has been constructed using statistical data.Pollutant load from each sub-region has been divided into several rivers based on geographic information.And attenuation coefficients have also been adopted to calculate the pollutant load into sea for each river.These coefficients represent the decay of pollutants from their origin to sea.The method was applied to calculate total nitrogen (TN) and total phosphorus (TP) load into sea from Tianjin from 2000 to 2014.The results show that:annual-mean TN and TP load into sea are 9 940.7 t and 663.4 t respectively; in 2012 both TN and TP flux into sea reach the maximum, which are 12 304.1 t and 830.0 t respectively; in 2000 both TN and TP flux into sea are minimum, which are 7 604.1 t and 494.0 t; the pollutant load into sea through Yongdingxin river occupy the largest proportion of the whole pollutant load into sea from Tianjin; agricultural land runoff and livestock industry take up most of TP load into sea while TN load into sea from each source is very close with each other; pollutant load into sea from each sub-region synthetically reflects factors such as population, economic development and pollution abatement.To protect the nearshore environment of Tianjin, industrial wastewater pollution from Binhai New District, domestic wastewater pollution from Haihe river and agricultural land runoff and livestock industry pollution from Yongdingxin river should be controlled mainly to reduce pollutant load into sea.

Abstract:
Dissolved organic matter (DOM) plays a key role in the marine biogeochemical cycle.Deciphering chemical composition and property of marine DOM is prerequisite to understand environmental behaviors of important biogenic elements (e.g., carbon and nitrogen).Recent development and application of advanced analytical techniques open a new window for chemical characterization of DOM at the molecular level.Compared to freshwater DOM, marine DOM not only has extremely low carbon concentration and complex chemical composition, but also is associated with high inorganic salt concentration.Some spectral techniques, such as ultraviolet-visible and three-dimensional fluorescence spectra, can analyze seawater DOM after filtration; however, the separation and enrichment of seawater DOM are required for high resolution analysis by mass spectrometry and nuclear magnetic resonance.In this review, we summarize the commonly used separation/enrichment methods, including solid-phase extraction (SPE), reverse osmosis/Electrodialysis (RO/ED) and ultrafiltration (UF), discuss the advantage and limitation of each method, and provide a perspective on future research direction of marine DOM.
