Data Source Data used for the production of this map are from NGDC, Boulder, and additional US, Italian, German, and New Zealand data sources. Only marine surveys using satellite navigation or GPS navigation control are used. Detailed bathymetry in northwest Ross Sea is based on multibeam data, primarily recorded by RVIB N B Palmer. Where data coverage is sparse (see data coverage diagram) contours are based on the ETOPO2 database (http://www.ngdc.noaa.gov/mgg/global/global.html). Bathymetry under the northern part of the Ross Ice Shelf are from marine surveys which the ice shelf has subsequently moved over, or from over-ice seismic surveys and traverses. Coastline and ice shelf edge (blue line) and land/ice topography from Antarctic Digital Database (http://www.add.scar.org/add_main.html). Franklin Island has been relocated 8 km to the south-southeast of its previously mapped location as a result of recent surveys.
Major national bases
Contours shown are in corrected metres (based on Carter’s Tables (1987) or velocity profiles based on XBT data where available). Contours are at 50m intervals on the shelf and 100m intervals in deeper water. Not all contours are shown in areas of steep topography.x Spot depth.
