Plan view of small arcuate slump scars that characterize the inner face of levees bounding a Pleistocene deep-water channel in approximately 2000 m of water in the northeastern Gulf of Mexico. This channel lies approximately 80 m below the sea floor and was characterized by flows from right to left. Colors indicate time structure, with warm colors representing bathymetric highs and cool colors representing bathymetric lows. Note that channel fill is characterized by positive relief associated with post-depositional differential compaction. The volume of materials excavated in association with these slumps likely was less than 100 m3 (after Posamentier, H.W., 2003, Depositional elements associated with a basin floor channel-levee system: case study from the Gulf of Mexico: Marine and Petroleum Geology, v. 20, p. 677-690). Image presented at the "Frontiers of Seismic Geomorphology" showcase held at the Geological Society, London, June, 2010.
