PI53A:
(Sub)mesoscale Physical/Biogeochemical Interactions II

Session ID#: 92468

Session Description:
High-resolution observations reveal rich spatio-temporal variations in marine biogeochemistry and ecosystems at the ocean mesoscale and submesoscale (defined here as (sub)mesoscale and spanning 1-100km and a few days to weeks). In addition, recent observations and modeling efforts have shown that (sub)mesoscale ocean physics plays a crucial role in structuring (sub)mesoscale biogeochemical and ecosystem variability, from nutrients and plankton to apex predators. This session aims to advance our understanding of (sub)mesoscale ocean biogeochemistry and ecosystems.  We invite all contributions that investigate the fundamental properties, mechanisms and/or broader implications of (sub)mesoscale spatial/temporal variability of marine biogeochemsitry and ecosystems. Contributions highlighting novel approaches and technologies or new synergistic combinations of existing approaches and technologies are particularly encouraged.
