In February, the “Coastal oxygen and hypoxia in Asian waters (Coastal-Oxygen)” project, led by Zhang Wenxia, associate researcher of the State Key Laboratory of Satellite Ocean Environment Dynamics of the SIO, and jointly applied by a number of high-level universities and scientific research institutions at home and abroad, was successfully approved, becoming the fourth approved “Decade of Ocean” project of the SIO.
The Coastal-Oxygen project aims to understand the deoxygenation process and seasonal hypoxia disasters in Asian coastal waters driven by climate warming and eutrophication. Due to the intensification of climate warming and eutrophication, the global oceans are losing dissolved oxygen at an alarming rate, especially in offshore areas, which have posed a real threat to the ecosystem. Asia is a region with rapid population growth and the region with the greatest potential for future economic development. Identifying the coupling effect of eutrophication and global warming on offshore dissolved oxygen is crucial for developing science-based strategies to alleviate offshore hypoxia.
Relying on the “Global Ocean Oxygen Decade” scientific program, this project is hosted by the SIO, and attended by 11 universities and research institutions from Japan, South Korea, the United Arab Emirates, Thailand and China. International cooperation inside and outside the project will be carried out through academic forums, technical training, exchange visit, data sharing, etc. The project aims to establish a long-term cooperation mechanism for dissolved oxygen in Asian coastal countries, build a water quality monitoring plan for dissolved oxygen and a multi-resolution hydrodynamic-biogeochemical coupling numerical model to identify early warning signals of nearshore hypoxia, combine the numerical model with artificial intelligence technology to develop the nearshore hypoxia warning system, greatly enhance China’s influence in participating in international marine dissolved oxygen reduction response actions, and provide scientific support for the sustainable development of nearshore ecosystems.
