To clarify the sustainable productivity of the ocean, it is important to know how much biomass could be generated through primary production. Then to know where the nutrients for the primary production come from is one of the most important issues to evaluate the biological production change caused by global warming in the marginal seas. In addition, oceanographic physical conditions, such as stratification, vertical mixing and horizonal transport, are quite important to control the behavior of nutrients. In this session, we will provide a platform to exchange the physical, chemical and biological information to understand primary production in the coastal and marginal seas with the key-word nutrient footprint. We expect to hear about various approaches concerning the behavior of nutrients, such as field studies, satellite remote sensing, numerical experiments with physical, chemical, and biological sensing along with interaction with the social sciences in East and Southeast Asia.
An ongoing UN Ocean Decade Incubator-WESTPAC programme, "Healthy, Productive and Sustainable Asian Marginal Seas: Understanding changes in the marine environment in response to global climate change", and its related projects and studies will also be briefly introduced in this presentation. Achieving a healthy and sustainable terrestrial and coastal water requires keeping track and assessing how these areas are changing. Enhancing the use of interdisciplinary cutting-edge science, technology and networks will contribute to the development of an international strategy to better understand current coastal and terrestrial ecosystems, particularly in the Asian Marginal Seas and its environs.
