MG51A:
Sediment Delivery, Transport, and Deposition in Marine and Lacustrine Environments I
Session ID#: 92438
Session Description:
Sediment transport processes are relevant to many areas of marine and lacustrine sciences because direct influences of water column turbidity, and particulate transport impact processes including biogeochemical cycles and benthic habitat evolution. Additionally, the form and character of sedimentary created provide clues as to the transport processes and environments present during their emplacement. Recent advances in theoretical, observational, and numerical modeling techniques have led to a more integrative understanding of the processes and products of sediment delivery, transport and deposition in aquatic environments; including lakes, estuaries, continental shelves, and the deep ocean. Sediment texture in these environments is often mixed bed or patchy, and includes a wide range of grain sizes including fine-grained muds, sands, and even gravels. This session showcases emerging research relevant to these environments covering physical forcing, particle behavior, modes of transport, morphodynamic feedbacks, and event stratigraphy. The session especially welcomes studies that consider the impacts of sediment transport across disciplines including biogeochemical and contaminant feedbacks. Studies in this session may derive from field observations, laboratory experiments, and modeling across a range of spatial and temporal scales.
