B43A:
Physical-Biogeochemical Coupling in Oceanic Eddies and Fronts: From Submesoscale to Mesoscale Processes I


Session ID#: 11489

Session Description:
Eddies, fronts, and upwelling systems are ubiquitous features with essential contributions on disturbing and transporting materials and energies in the global ocean. Physical and biogeochemical processes in these systems have been long recognized as “dynamically active” that are typically different from basin-scale adjustments. With recent advancements in in-situ monitoring, remote sensing and high-resolution numerical models, physical-biogeochemical coupling in these systems indicates prominent spatial and temporal variability that could be potentially related to the nature of mesoscale and submesoscale dynamics. Systematic understanding of the underlying dynamics is required to better interpret observed ocean biogeochemical variations, which can further advance the understanding of global carbon cycle and ultimately climate change. Both observations (in situ and satellite) and numerical models are able to provide clues to how these dynamics affect ocean biogeochemistry from nutrient cycling to ecosystem structures, as well as how ocean biogeochemistry evolve with mesoscale and submesoscale dynamics. In this session, we welcome contributions from any discipline that examine topics about physical-biogeochemical coupling related to mesoscale and submesoscale dynamics from snapshots to long-term temporal scales. Researches that address impacts of eddies, fronts, and upwelling systems on biological, chemical, and high-trophic level processes are particularly encouraged for submission.
