The GEBCO "One-Minute Grid" is based on the most recent version of the GEBCO Digital Atlas (GDA) bathymetric contours. Additional control contours and sounding data were used in many regions, particularly shallow water areas and semi-enclosed seas, to constrain the gridding process. It is a continuous digital terrain model for ocean and land, with land elevations derived from the Global Land One-km Base Elevation (GLOBE) database. As GA is only interested in the bathymetry in the Australian Region, the downloaded file was edited so that only the values in the Extents Box remained. The extract extends from 5°S to 80°S and from 45°E to 180°E. It must be stressed that although the GEBCO One Minute Grid is presented at one minute intervals of latitude and longitude, this does not imply that knowledge is available on sea floor depth at this resolution. It is important to note that, in most places, many miles exist between adjacent ship tracklines and that the grid is an interpolation based upon the input data. Further details of the data compilation and GEBCO grid construction are available from the 'User guide to the GEBCO One Minute Grid' ( http://www.bodc.ac.uk/data/online_delivery/gebco/documents/gridhelp.pdf).
