A composite 5-minute gridded bathymetry of the Southern Ocean was derived from combining satellite radar altimetry data (Smith and Sandwell, 1997) and the GEBCO-1997 (IOC et al., 1997) digital isobaths.

This bathymetry was used during the last step in the quality control of the Southern Ocean Database to correct or assign missing
water depths to about a quarter of the stations. It was projected between stations to construct the high-resolution bottom
the masks for the vertical sections, and for the
depth and neutral density maps.
