The Impact

The rapid social-economic development of the countries bordering the South China Sea has resulted in increased marine pollution of the region, yet little study has been carried out on marine pollution in the region. This article is one of the first few attempts among existing literature to understand marine pollution in the South China Sea as a large marine ecosystem and its implications for sustainability. We have conducted systematic literature reviews for marine pollution in the South China Sea and three other regional seas/large marine ecosystems, namely, the Gulf of California, the Mediterranean Sea, and the North Sea with the assistance of CiteSpace. By comparison of studies in the three regional seas, the research of marine pollution in the South China Sea only touches on the impact of microplastics, and existing literature in the area is less efficient in the study of impacts of modern pollution on marine organisms and the uncertain bioaccumulation effect on humanity. Therefore, it is recommended that researchers in the region cooperate to conduct a holistic study of ocean pollution, and study of biological impacts of pollution on marine organisms should be strengthened.

The Impact

The South China Sea, including the Vietnam Sea, is witnessing significant changes under the impact of both nature and man. These are the impacts of climate change and ocean change with "extreme" signs such as increasing storms, coastal floods, sea level rise, sea acidification, pollution and environmental incidents, ... occur thicker, more intense and irregular. Especially serious degradation of the environment and biodiversity of the sea, increasing environmental incidents, including oil spills, ... due to human impact. Especially the large-scale destruction of coral reefs, seagrass beds in island clusters off the South China Sea has been happening at a worrying rate. The destructive fishing activities of humans in the South China Sea have caused ecosystem degradation and the extinction of some species, such as sea turtles, some sharks and another species. Other fish, especially the giant mussel, the consequence is a decrease in the natural capital of the sea, leading too prolonged "ecological disturbances". The reserves of seafood in the Spratly region (of Vietnam) and the West Sea in the East Sea have decreased by about 19% compared to before 2017. Therefore, the improvement of marine environment quality, including biodiversity conservation and major marine ecosystems are to preserve marine natural assets, contributing to the implementation of Vietnam's green growth strategy and action plan. This is the path that Vietnam has chosen to both grow marine economy, adapt to climate change, and protect the environment both in the short and long term, towards sustainable development.

AbstractMarine picoplankton, including prokaryotic and eukaryotic picoplankton, drive many biogeochemical processes, such as carbon, nitrogen and sulfur cycles, making them crucial to the marine ecosystem. Despite the fact that picoplankton is prevalent, its diversity and spatial distribution from the Straits of Malacca (SM) to the South China Sea (SCS) remain poorly investigated. This work explores the phylogenetic diversity and community structure of picoplankton in relation to environmental factors from the SM to the SCS. To this end, the Illumina MiSeq sequencing technique was applied to 16S and 18S rRNA genes. The results showed significant differences in the dynamics of picoplankton between the open sea and the strait region. Proteobacteria and Cyanobacteria constituted a larger part of the prokaryotic group. Within Cyanobacteria, the abundance of Prochlorococcus in the open sea was significantly higher than that of Synechococcus, while the opposite trend was observed in the strait. Dinoflagellata, Cnidaria, Retaria, Tunicata, and Arthropoda dominated among the eukaryotic taxa. High-throughput sequencing data indicated that salinity, temperature and NO2-N were the key factors determining the prokaryotic community structure, while temperature and dissolved oxygen determined the eukaryotic community structure in the studied region. The network analysis demonstrated that the cooperation and competition were also important factors affecting the picoplankton community.

Large Marine Ecosystem

The South China Sea Large Marine Ecosystem is one of the world’s richest marine biodiversity areas. The sea area is however the site of increasing tensions between its ten coastal States, six of which have competing claims in the South China Sea. The expanding populations and economies of the coastal States have also resulted in the growing depletion of the Sea’s rich marine resources. Coordinated approaches are needed to protect the unique biodiversity and natural resources of the South China Sea at the appropriate ecological scale. The continuation of sovereignty disputes are detrimental to all coastal states as well as international economic interests of non-claimant states which arise as a result of the Sea’s status as a globally important trade route. This paper urges coastal states to adopt a far-sighted outlook which ensures long-term sustainable ecosystems, livelihoods and economies of the region. To do this, a shift in approach which emphasises collaborative management of marine ecosystems is required instead of a scramble for sovereignty to exclusively exploit living and non-living resources. This paper therefore explores how the shared governance arrangement of a condominium could facilitate the exercise of sovereignty for the shared benefit of all coastal States. The paper argues that the condominium approach would enable State parties to put aside thorny sovereignty disputes in favour of collaboration to protect the area’s important and unique biodiversity.

In this communication, selected results obtained in the course of a 10-year Sino-Italian collaborative project are presented. During this collaboration, several studies on marine organisms collected in the South China Sea have been conducted, resulting in the characterization of a large number of novel natural products. The main interest has been focused on sponges, cnidarians, and molluscs. Here, the recent research, including some not yet published studies, on cnidarians and molluscs, in particular, opisthobranchs and pulmonates, will be briefly described. The study of cnidarians and pulmonates led to isolate molecules, in particular, biscembranoids and polypropionates, displaying carbon skeletons already described in previous papers. Our studies resulted in their complete structural characterization including the absolute stereochemistry that was clarified by coupling X-ray diffraction to circular dichroism (CD) spectra analysis. Some unique nitrogenous molecules containing either an isonitrile function or an 1,2,4-oxadiazole moiety, this latter found for the first time in a marine organism, as well as known sesterterpenoids and diterpenoids were isolated from opisthobranchs. Owing to their anatomical location, these metabolites should play a relevant role in the protection of the molluscs. Finally, a series of alkaloids structurally related to known anticancer agents were also characterized.
