Processes controlling the formation of the Mertz Drift, George Vth continental shelf, East Antarctica: evidence from 35 Khz sub-bottom profiling and sediment cores

Updated: 2018-04-22

Recently discovered drift deposits on the Antarctic continental shelf provide access to information on the Holocene palaeoceanography of the bottom current regime within deep shelf basins that were previously inaccessible. The George Vth Basin on the East Antarctic margin has been identified by oceanographers as an important source of Antarctic Bottom Water, hence the Holocene history of bottom current activity here may be relevant to variations in bottom water export.
