國家海洋局2017年3月22日發(fā)布了《2016年中國海洋環(huán)境狀況公報》。公報顯示，2016年我國海洋生態(tài)環(huán)境狀況基本穩(wěn)定，海水質(zhì)量總體較好，生物多樣性保持穩(wěn)定，海洋功能區(qū)環(huán)境基本滿足使用要求。但是，陸源入海污染壓力巨大，近岸局部海域污染嚴重，典型海洋生態(tài)系統(tǒng)健康狀況不佳，海洋環(huán)境風險依然突出。

The European water framework directive: A challenge for nearshore, coastal and continental shelf research

Borja, A

Abstract:The European Water Framework Directive (WFD) establishes a framework for the protection of groundwater, inland surface waters, estuarine waters, and coastal waters. The WFD constitutes a new view of the water resources management in Europe because, for the first time, water management is: (i) based mainly upon biological and ecological elements, with ecosystems being at the centre of the management decisions; (ii) applied to European water bodies, as a whole; and (iii) based upon the whole river basin, including also the adjacent coastal area. Although the marine water bodies affected by the WFD relate to only 19.8% of the whole of the European continental shelf, its application constitutes a challenge and an opportunity in nearshore, coastal and continental shelf research. This contribution highlights some of the main tasks and the research to be undertaken in the coming years, proposing investigations into: typologies; physico-chemical processes; indicator species; reference conditions; integration of the quality assessment; methodologies in determining ecological status, etc.

The standard SeaWiFS atmospheric correction algorithm, designed for open ocean water, has been extended for use over turbid coastal and inland waters. Failure of the standard algorithm over turbid waters can be attributed to invalid assumptions of zero water-leaving radiance for the near-infrared bands at 765 and 865 nm. In the present study these assumptions are replaced by the assumptions of spatial homogeneity of the 765:865-nm ratios for aerosol reflectance and for water-leaving reflectance. These two ratios are imposed as calibration parameters after inspection of the Rayleigh-corrected reflectance scatterplot. The performance of the new algorithm is demonstrated for imagery of Belgian coastal waters and yields physically realistic water-leaving radiance spectra. A preliminary comparison with in situ radiance spectra fbr the Dutch Lake Markermeer shows significant improvement over the standard atmospheric correction algorithm. An analysis is made of the sensitivity of results to the choice of calibration parameters, and perspectives for application of the method to other sensors are briefly discussed.來源出版物：Applied Optics, 2000, 39 (6): 897-912Large groundwater inputs to coastal waters revealed by226Ra enrichmentsMoore, WS

The flow of ground water directly into the coastal ocean has been studied previously by in situ measurements, seep meters and diffusion gradient models’. Although these techniques provide ample evidence that such flows occur, they do not provide a means of quantifying the groundwater flux on a regional scale. Here I report large enrichments of226Ra in coastal waters of the South Atlantic Eight, and demonstrate that groundwater discharge is the main source of the226Ra surplus. Using226Ra data for brackish ground waters with estimates of residence times of nearshore waters, I conclude that the groundwater flux to these coastal waters must be about 40% of the river-water flux during the study period. Besides Ra, other metals, nutrients and organic compounds are expected to be enriched in brackish ground waters, so these findings require an upward revision of terrestrial fluxes of dissolved materials to these coastal waters, andperhaps a re-evaluation of such fluxes to the global ocean. These fluxes may be sensitive to hydrological factors, groundwater usage, dredging and sea-level change.來源出版物：Nature, 1996, 380 (6575): 612-614Couplings of watersheds and coastal waterssources and consequences of nutrient enrichment in waquoit bay, massachusettsValiela, I; Foreman K; Lamontagne M; et al.Abstract:Human activities on coastal watersheds provide the major sources of nutrients entering shallow coastal ecosystems. Nutrient loadings from watersheds are the most widespread factor that alters structure and function of receiving aquatic ecosystems. To investigate this coupling of land to marine systems, we are studying a series of subwatersheds of Waquoit Bay that differ in degree of urbanization and hence are exposed to widely different nutrient loading rates. The subwatersheds differ in the number of septic tanks and the relative acreage of forests. In the area of our study, groundwater is the major mechanism that transports nutrients to coastal waters. Although there is some attenuation of nutrient concentrations within the aquifer or at the sediment-water interface, in urbanized areas there are significant increases in the nutrient content of groundwater arriving at the shore's edge. The groundwater seeps or flows through the sediment-water boundary, and sufficient groundwater-borne nutrients (nitrogen in particular) traverse the sediment-water boundary to cause significant changes in the aquatic ecosystem. These loadingdependent alterations include increased nutrients in water, greater primary production by phytoplankton, and increased macroalgal biomass and growth (mediated by a suite of physiological responses to abundance of nutrients). The increased macroalgal biomass dominates the bay ecosystem through second-or third-order effects such as alterations of nutrient status of water columns and increasing frequency of anoxic events. The increases in seaweeds have decreased the areas covered by eelgrass habitats. The change in habitat type, plus the increased frequency of anoxic events, change the composition of the benthic fauna. The data make evident the importance of bottom-up control in shallow coastal food webs. The coupling of land to sea by groundwater-borne nutrient transport is mediated by a complex series of steps; the cascade of processes make it unlikely to find a one-to-one relation between land use and conditions in the aquatic ecosystem. Study of the process and synthesis by appropriate models may provide a way to deal with the complexities of the coupling.來源出版物：Estuaries, 1992, 15 (4): 443-457Origin of polycyclic aromatic hydrocarbons (PAHs) in coastal marine sediments: Case studies in Cotonou (Benin) and Aquitaine (France) areasSoclo, HH; Garrigues, P; Ewald, MAbstract:Polycyclic Aromatic Hydrocarbons (PAHs) were identified and quantified in recent sediments of the Cotonou coastal zones (Benin) in the total concentration range 25-1450 ng·g-1, while the Aquitaine sediment samples (France) exhibited total PAH concentrations in the range 4-855 ng·g-1. The highest contents of PAHs were found in the harbours, as well in Cotonou as in the Aquitaine region, with the maximum values in the Cotonou harbour. However, the PAH concentrations were comparable with those of slightly contaminated zones. Good correlations observed between a certain number of pairs of isomer PAH concentrations allowed to identify six origin molecular indices that were used to identify the PAH contamination sources in the studied sampling stations: Phe/ An, Flt/Py, Chry/BaA, LMW/HMW, Per/Sigma(PAH), and Per/Sigma(penta-aromatics). In general, the Cotonou lagoon sampling sites were contaminated mainly by petrogenic PAHs, due to petroleum trade at individual scale along the lagoon, and also waste oils from mechanics shops; the Aquitaine samples were polluted by pyrolytic origin PAHs. Interferences of rather petrogenic and pyrolytic PAH contaminations,pere noticed in the harbours due to petroleum products deliveries and fuel combustion emissions from the ships staying alongside the quays. Diagenetic origin of perylene was confirmed in this study, but its possible formation by combustion of organic matter was also considered because of the relatively higher concentrations of this PAH in the harbours of Cotonou and of Aquitaine region sediment samples.
