GM8.2/CR6.4Submarine Geomorphology of Glaciated Continental Margins (co-organized)
|Convener: Dayton Dove | Co-Conveners: Daniel Praeg , Colm O'Cofaigh , Stephen McCarron|
The submarine geomorphology of glaciated continental margins is increasingly recognised to provide detailed signatures of the sedimentary processes operating beneath and beyond former ice sheets. Reconstructions of the extent and dynamics of past glaciations rely on geomorphological approaches, whether through identifying landform assemblages at seabed, or observing buried surfaces using sub-bottom data. This session aims to bring together researchers utilizing a range of data types (e.g. high-resolution swath bathymetry, 2D/3D seismic reflection data, sediment cores) to study landform creating processes in subglacial to ice marginal environments that are now submarine, and to understand their implications for glacial history of these regions. A clearer picture of the extent, dynamics and timing of past glaciation provides necessary boundary conditions for numerical models of ice sheet interactions with the ocean during changing palaeoclimates. Such studies are also of direct relevance to offshore industries and marine spatial planners interested in characterizing seabed and shallow sub-seabed resources along formerly glaciated margins.
