Ocean Climate and Marine Ecosystems in the Western Pacific
Sub Theme
- Innovative observational studies concerning physical or biogeochemical processes in coastal and marginal seas are needed. Development and assessment of instruments or observing systems (e.g. fixed in-situ, satellite, ferries, floats, gliders, HF Radar) which provide the data required for oceanic studies will be mentioned, too.
- Ocean acidification, caused by a rapid rise in anthropogenic emissions of carbon dioxide (CO2), is rapidly changing ocean chemistry. A cooperative researches and knowledge-sharing collaborations including regional networking programs for ocean acidification beyond geopolitical boundaries are desperately needed.
- Recent developments in the coupled climate modeling, ensemble, prediction results and the understanding of the interactions between ocean and atmosphere.
- Under the influence of climate change, it is important to predict the changing trend of air-sea interactions from the frequency and strength of storms to the response of the thermal structure of the upper layer by observing and modeling the sea state.
- Ecosystem changes caused by anthropogenic impacts, such as eutrophication, chemical pollution, overfishing, hypoxia and habitat modification and how climate change influences anthropogenic impacts and ecosystem
- Marine remote sensing provides a window on synoptic scales. It is the sole method to take a global view of marine biosphere and monitor the ocean environments as climate change, water quality, fishery, and species at risk.
- Assessment of regional as well as global impacts of natural disasters related to the climate change and developments of natural disaster reduction and mitigation systems will be covered.
- The past climatic records which are monsoons evolution and effects such as linkage between terrestrial and ocean records, and other records from trees, corals, sediments, glaciers and other natural or proxy sources.
- It is predicted that 15% of the world’s coral reefs are under imminent threat of joining the "Effectively Lost" category within the next 10-20 years. These predictions are based on observed trends over the past decade, on demographic increases in human population pressure, and assessments of the effectiveness of current management.
- Most of coastal countries have been suffering from natural and man-made coastal erosions. Sound coastal management integrating various areas and considering the effects of climate change as well as development of new technology for erosion control is prerequisite for sustainable development of coastal zone.
Understanding the biogeochemical cycling of materials (salt, carbon, nutrients, trace elements etc.) requires knowledge of their diverse sources and sinks, as well as their transport and chemical form in the ocean. Without this understanding, the impact of any resulting changes due to human activity in elemental cycling on marine ecosystems and the global carbon cycle cannot be meaningfully predicted.
- Marine biodiversity in the Western Pacific, especially in the coral triangle, is highest in the world ocean providing a rich source of food and biomaterials. Yet, a significant number of marine organisms remain to be discovered and identified.
- The abundance, distribution of major fish species and fisheries, species composition in ecosystem, and some social issues on economy can be altered by the climate changes. It is important to describe the climate change impacts on fish and fisheries and discuss conservation measures for mitigation and preparation in fisheries.
- The best way to mitigate impacts for environmental sustainable aquaculture is to utilize an organic aquaculture. It will provide eco-friendly guidance to improve the environmental performance of sustainable aquaculture.
