Geologic Evolution of Continental Shelves I Posters


Submit an Abstract to this Session


Session ID#: 48962

Session Description:
The geologic evolution of continental shelves is linked to large-scale driving mechanisms including tectonics, climate, and sea level variations. On shorter timescales, processes that shape continental shelves include sediment dynamics associated with waves, tides and currents, as well as biologic activity and submarine groundwater discharge. These processes operate across various spatial and temporal scales, adding complexity to interpretations linking processes to morphology. Furthermore, continental shelves cycle between subaerial exposure and submergence associated with sea level fluctuations that repeatedly reshape the shelf and render the shoreline an artificial boundary in landscape evolution. We encourage submissions from onshore and offshore studies that investigate a broad range of topics including fluvial drainage history, sediment dynamics, paleoshorelines, drowned landscapes, shelf morphology and geologic framework controls on benthic habitats from both passive and active continental shelves worldwide. We welcome contributions from field observations including geophysical surveys, outcrop and core studies, landscape modeling, and laboratory experiments.
