A bathymetric Digital Elevation Model (DEM) of the George V and Terre Adelie continental shelf and margin
Entry ID: GVdem_2008

Abstract: This dataset comprises Digital Elevation Models (DEMs) of varying resolutions for the George V and Terre Adelie continental margin, derived by incorporating all available singlebeam and multibeam point depth data into ESRI ArcGIS grids. The purpose was to provide revised DEMs for Census of Antarctic Marine Life (CAML) researchers who required accurate, high-resolution depth models for correlating ... View entire text

SHIPS Ancillary Description
ECHO SOUNDERS Ancillary Description
Quality The various multibeam datasets were processed within acquisition software by the originating agencies in order to correct for sound velocity variations within the water column and the removal of noise. No account has been taken of tidal range, so all depth data is assumed to have a vertical datum of mean sea-level (MSL). The final DEMs conform to Order 2 of the International Hydrographic ...
