[A-OS14] [EE] Marine ecosystems and biogeochemical cycles: theory, observation and modeling

Mon. May 22, 2017 3:30 PM - 5:00 PM 303 (International Conference Hall 3F)

convener:Takafumi Hirata(Faculty of Environmental Earth Science, Hokkaido University), Shin-ichi Ito(Atmosphere and Ocean Research Institute, The University of Tokyo), Eileen E Hofmann(Old Dominion University), Enrique N Curchitser(Rutgers University New Brunswick), Chairperson:Shin-Ichi Ito(Atmosphere and Ocean Research Institute, The University of Tokyo), Chairperson:Taka Hirata(Hokkaido University)

The ocean accounts for about 50% of the global net primary production on our planet. This production is significant for carbon cycling and ecosystem functioning, and is related directly or indirectly to a variety of climatic and ecological phenomena. The responses to natural and anthropogenic environmental stressors that influence marine production and diversity can cause perturbations to marine ecosystems that alter trophic dependencies and interactions among organisms at a range of space and time scales. Quantification of the principal mechanism(s) driving spatio-temporal variability of marine ecosystem remains to be done, especially in terms of evaluation of uncertainty in responses. As a result, evaluating vulnerability of marine ecosystems to environmental change requires systematic and holistic approaches that integrate physics to ecology and are based in observations and modelling. This session aims to provide a venue for discussing recent achievements in marine biogeochemical and ecosystem studies that will lead to better understanding of the Earth system.
