EP43A:
Aquatic Flux Studies: New Ecological Findings and in Situ Approaches II


Session ID#: 37833

Session Description:
Fluxes in the benthic environment, at the air-water interface, or in the water column in between are critically important in aquatic ecosystem studies. Uses of flux estimates include studies of biogeochemical processes, exchange processes, cycling of matter, and budget calculations for a variety of constituents on scales ranging from local sites, to regional networks, and up to a global scale. This session invites contributions that present new scientific findings gained from aquatic fluxes that are either measured directly or assessed by other means for nearshore, shelf, slope and deep sea environments, or for freshwater systems such as lakes and rivers. Work focusing on spatial and temporal variability of fluxes, their magnitude, controlling factors, and their biogeochemical and ecological effects on aquatic systems are particularly welcome. We also invite presentations on methodological advances for determining aquatic fluxes, including new sensors, new in situ or remote approaches, and modeling work.
