MG34A:
Physical and Biogeochemical Processes at the Sediment-Water Interface in Estuaries, Coastal Oceans, and Shelf Seas III Posters


Session ID#: 7911

Session Description:
Benthic processes and the resulting fluxes at the sediment-water interface are highly significant in the shallow waters that characterize estuaries, coastal oceans and shelf seas. Many physical and biogeochemical processes influence benthic-pelagic exchange, and near-bed fluxes and transport of sediments, nutrients, carbon and other bioactive solutes. Sediment resuspension and bed reworking by tides, waves, and biological activity are frequent in the energetic coastal environments considered. Dissolved material can be exchanged by diffusive and pumped/advective processes. The interactions between the flows and large and small scale seafloor morphology are complex and can modify flux rates. Particulate matter settles and accumulates in an unconsolidated fluff layer easily remobilised by bottom currents. Our understanding of these processes nevertheless remains limited to date, and fully elucidating the benthic-pelagic exchanges requires approaches encompassing biology, chemistry, physics, and the interactions and feedbacks between them. This session seeks contributions across these disciplines which directly address processes affecting cycling and fluxes at the sediment-water interface and in the near-bed boundary layer in estuaries, coastal oceans and shelf seas. This session will welcome studies based on in-situ observations, laboratory experiments, and modelling either resolving or parameterizing processes.
