Kerguelen-Heard Island region - Mapping Under Sea Geomorphology
The geomorphology was digitised using contours derived from the DEM created by Dr. R. Beaman from James Cook University for Geoscience Australia. The data, the metadata record and the report related to the creation of that DEM are available on the Geoscience Australia website: Name of data set: Kerg...
