Lineage/Methodology:

The bathymetry map was compiled from a variety of different data sources. The primary data are multibeam swath bathymetry collected from scientific cruises undertaken by British Antarctic Survey (BAS), or acquired during RV Nathaniel B. Palmer, RV Surveyor, RV Maurice Ewing and RRS James Cook expeditions. The complete list of the cruises used for the compilation is described below: James Clark Ross expeditions: JR59, JR69-67, JR71, JR81, JR84, JR93, JR112, JR115, JR149, JR150, JR158, JR179, JR185, JR188, JR193-196, JR194-197, JR228, JR230, JR233, JR239-235-236, JR240, JR244, JR252-254c, JR254D-264-265, JR255A, JR276, JR279-286, JR281, JR299, JR306-307, JR312, JR15003, JR16002, JR16003, JR17003, JR17003A Ewing cruise: EW9101 James Cook cruises: JC055, JC054 NB Palmer cruises: NBP9507, NBP9902, NBP9903, NBP9904, NBP9905, NBP0001, NBP0002, NBP0003, NBP0106, NBP0107, NBP0201, NBP0202, NBP0502, NBP0602A, NBP0603, NBP0606, NBP0703, NBP0710, NBP0805, NBP0908, NBP1001, NBP1003, NBP1103, NBP1105, NBP1107, NBP1203, NBP1304, NBP1602, NBP1603, NBP1608 Surveyor cruises: AMLR95, RITS93A, RITS94B, AMLR90, AMLR92, AMLR94 The grid was created using the mbgrid program from MB-system version 5.5.2336 , using the parameters " -E0.001/0.001/degrees! -G4 -A2 -F1 -R-63/-53.3/-63.50/-60.5" for Arc/Info and ArcView ASCII grid and " -E0.001/0.001/degrees! -G3 -A2 -F1 -R-63/-53.3/-63.50/-60.5" for the netCDF file. This uses a Gaussian weighted mean filter and the bathymetry is gridded as topography (positive upwards)
