ME53A:
Underwater Flux Studies and Their Ecological Implications I
Session ID#: 93073
Session Description:
Fluxes of oxygen, carbon dioxide, methane, trace elements, and other constituents across the benthic boundary, the air-water interface, and within the water column are critically important quantities in marine and freshwater ecosystem studies. Fluxes are used to study biogeochemical transformations and exchange processes, and in carbon budget calculations on scales ranging from local sites to the global environment. This session invites contributions that present new scientific findings gained from underwater flux studies in marine and freshwater systems, including coastal, shelf, and deep sea environments, and also rivers and lakes. Work focusing on spatial and temporal variability of fluxes, their magnitudes, controls, and ecological implications are welcomed. We also invite presentations on methodological advances for determining underwater fluxes, including new in situ approaches, new sensors, and modeling work.
