[A-CG40] Coastal Ecosystems - 1. Water Cycle and Land-Ocean Interactions

Tue. May 28, 2019 9:00 AM - 10:30 AM 102 (1F)

convener:Masahiko Fujii(Faculty of Environmental Earth Science), Makoto Yamada(Faculty of Economics, Ryukoku University), Jun Shoji(The University of Tokyo), Ryo Sugimoto(Faculty of Marine Biosciences, Fukui Prefectural University), Chairperson:Masahiko Fujii, Makoto Yamada

Substances from land which are brought by river and/or submarine groundwater discharge are important for the process of biological production in coastal areas. This session focuses on land-ocean interactions through water cycle. The aim of this session is to create interdisciplinary discussions on the research of connectivity of ecosystems, water cycles in terrestrial and coastal areas, fishery resources and biodiversity. Comprehensive discussion on the mechanisms that promote productivity and biodiversity in coastal ecosystems will be made from the viewpoint of land-ocean interactions. Presentations on water-material cycle in terrestrial and coastal areas, fishery resources, biodiversity and connectivity of the ecosystems are encouraged.
A companion session proposed as "Coastal Ecosystems - 2. Coral reefs, seagrass meadows, and mangroves" focuses on benthic communities in shallow-water ecosystems such as coral reefs, seagrass meadows and mangroves and is dedicated to promote researches on comprehensive assessment and monitoring of ecosystem functions and development of effective means for conservation and restoration. Main focuses of these two sessions are different. However, there are much of information that covers both sessions. Scientists who work on the related field will be able to obtain information and share them with other scientists if they attend to both of these sessions.
