TL;DR: In recent years, tighter control in the form of strict regulations, proper enforcement and monitoring, and mitigating measures together with proper impact assessment and development of new environmental dredging techniques help to prevent or minimize adverse impacts on seagrasses.

TL;DR: The presence and abundance of microplastics in sediments and seawater in Singapore is likely due to on-going waste disposal practices from industries and recreational activities, and discharge from shipping.

TL;DR: Comparison of the concentration range with a worldwide survey of sedimentary PAH concentrations ranked PAH contamination in Thai sediments as low to moderate, and indicated that street dust is one of the major sources of petrogenic PAHs in the urban area.

TL;DR: In this article, surface sediments in the <63-μm fraction collected from 34 sites at western part of Izmit Bay, Northeastern Marmara Sea, Turkey were analyzed by ICP-AES for Al, As, Cd, Co, Cr, Cu, Fe, Mg, Mn, Ni, Pb, Sn and Zn.

TL;DR: Two mathematical methods to assess the "health status" of flounder, eelpout and blue mussel populations of the Baltic Sea were applied on selected biomarker data collected during the EU project "BEEP" to produce essentially similar results.

TL;DR: It is hoped that through the recognition of the inter-dependence of the health of both humans and the oceans, efforts will be made to restore and preserve the oceans.

TL;DR: Nitrogen, in particular nitrate+nitrite, and not phosphorus, dissolved silicate, or their molar ratios, appears to be the major driving factor influencing the size of the hypoxic zone on this shelf, consistent with cross-system analyses that conclude that the TN:TP ratio in the Mississippi River, currently fluctuating around 20:1, is indicative of nitrogen, not phosphorus.

TL;DR: The overall conclusion is that the complicated interactions between variables and the lack of data induce difficulties in setting common or uniform environmental quality standards for benthic effects of fish farming and these should take into account the existing considerable differences between geographic regions, depth zones and sediment types.

TL;DR: The calculated hydrocarbon indexes suggest that petroleum contamination was the main source of n-alkanes, while both pyrolytic and petrogenic sources contributed PAHs to the surface sediments of Jiaozhou Bay.

TL;DR: The high likelihood of unreported fatal strikes combined with other anthropogenic threats suggests an urgent need for a comprehensive, basin-wide conservation strategy, including ship strike mitigation requirements, like real-time monitoring of whale presence and distribution to re-locate ferry routes to areas of lower cetACEan density, and reducing ship speed in high cetacean density areas.

TL;DR: The objective of this paper is to review the current state-of-the-art of the integration of AI into water quality modelling and to incorporate the existing heuristic knowledge about model manipulation and to furnish intelligent manipulation of calibration parameters.

TL;DR: The results obtained reflect the current knowledge of the state of the Humber environment and show the potential of integrative indicators but indicate that further studies are required to assess the relative importance of the indicators.

TL;DR: It is important to point out in the context of human health and HAB events, that in some coastal regions, HABs are an emerging problem, and the local population and visitors may face a health risk that is difficult to measure.

TL;DR: In this paper, the results showed that the concentrations of total aromatic hydrocarbons were found at all depths in the samples collected during December 2002 off the Galicia coast, with levels ranging between 0.19 and 28.8μg/L eq.

TL;DR: Marine monitoring and marine environmental research in combination is reviewed in combination and in the light of such major policy initiatives such as the WFD to achieve good ecological status across European surface waters.

TL;DR: Although measured levels of the downward flux of suspended particulate matter and suspended solids were well within "normal" levels recorded in the literature, it was the proportion of benthic space, generic coral composition, and site history that offered compelling evidence of chronic exposure to increased sediment load.

TL;DR: A newly established sub-population of Lophelia pertusa, the dominant reef-framework forming coral species in the north-east Atlantic, on oil and gas platforms in the northern North Sea is reported, suggesting that these colonies provide evidence for a planktonic larval stage of L. pertusa.

TL;DR: Results indicate that fishers using beach seines, spears and gill nets cause the most direct physical damage to corals, and the need to enforce restrictions on destructive gear and mesh sizes is emphasized.

TL;DR: It is demonstrated that brominated compounds from both anthropogenic and biogenic sources can accumulate to similar levels in marine mammals, and HBCD concentrations appear to be increasing in California sea lion populations, whereas PBDE concentrations, between 1993 and 2003, were highly variable.

TL;DR: It is concluded that FF with un-normalised data is a reliable and simple method for monitoring purposes and only one sex of a selected species should be used.

TL;DR: For both species, PAH exposure decreased as salinity increased whereas dispersant effectiveness decreased only at the highest salinity, Hence, risks to fish of PAH from dispersed oil will be greatest in coastal waters where salinities are low.

TL;DR: In a field study performed in spring and autumn 2001 and 2002, blue mussels (Mytilus edulis) and female eelpout (Zoarces viviparus) were collected at three locations in the Wismar Bay (Baltic Sea), and several biomarkers of contaminant effects were analysed as discussed by the authors.

TL;DR: It is demonstrated that under pre-European conditions, the nutrient enriching impact from river runoff was likely to have been largely constrained within 1-2 km of the coast, whereas existing conditions support the impact of reefs some 20-30 km off the coast.

TL;DR: The three indices were able to detect the major changes in macrofauna composition, which occurred in the Bay of Banyuls-sur-Mer during the last 40years, however, the interpretations of such changes in terms of EcoQ differed between indices.

TL;DR: Overall, employed biomarkers detected exposure to toxic chemicals and disturbed health in mussels from Bay of Biscay, with impact decreasing from April to September.

TL;DR: The managed realignment of coastal defences and subsequent creation of intertidal habitats is one of several 'soft' engineering options that could reduce the costs of maintaining embankments and at the same time deliver environmental benefits.

TL;DR: In this article, the response of a benthic community to hypoxia in organically enriched environments in Korean coastal waters was studied, showing that the number of taxa, their abundance and biomass of macrofauna dropped significantly at inner bay stations.

TL;DR: The Expert Consultation considered that the database for cyclic imines, brevetoxins, and pectenotoxins was insufficient to establish provisional acute RfDs for these three toxin groups.
