Coastal seas have high biodiversity and high productivity, while various environmental problems such as eutrophication, red tide, and hypoxia are caused by human activity. In order to understand the material cycle and various phenomena, and to maintain sustainable environment in coastal seas, interdisciplinary research is needed. Coastal processes are also affected by the water cycle from land to the ocean, involving complex dynamics of rivers and buoyancy-driven flows in estuaries and the ocean. Recent progress in satellite observations and numerical models are beginning to illuminate how this water cycle occurs on various time scales globally and regionally.
This session welcomes researchers who are interested in physical phenomena, material cycle, biological responsive dynamics, and their interactions in coastal seas as well as the freshwater cycle from land to the ocean such as surface runoff, river transport, estuarine circulation, and coastal river plumes. Neither study area nor study method is confined. We welcome studies on wide range of topics to communize our knowledge, including presentations in English.
