OB34F:
Marine Sediments: Fluxes, Fauna, and Forecasting II Posters
Session ID#: 84623
Session Description:
Marine sediments are home to a diverse assemblage of microbes and, as a result, are the setting for a wide array of biogeochemical cycles. From permeable sands to organic-rich muds, these environments support larger communities of benthic flora and fauna who, in turn, enhance biogeochemical cycling through bioturbation, nutrient delivery, and microbial gardening. Physical processes, such as advective flow and fluctuations in temperature, can lead to oscillating redox boundaries and altered rates of carbon burial. As sampling and research techniques have become more advanced, appreciation for the role of marine sediments in global biogeochemical cycles has grown. However, many marine sediment environments remain understudied and face a variety of immediate concerns, such as bottom trawling, seabed mining, deoxygenation in the overlying water, and increased sediment deposition following terrestrial soil erosion events. This session will combine modeling, laboratory, and field-based studies, especially ones that are multidisciplinary in nature, in an effort to further our understanding of marine sediments and more precisely predict their response to changing ocean conditions. Abstract topics may include, but are not limited to, biogeochemical fluxes, bioturbation/bioirrigation processes, organismal/microbial community structure and function, biophysical coupling, and human-mediated disturbances.
