The Geophysical Processing and Data Access (GPDA) project at Geoscience Australia has undertaken a programme of collating, editing and cataloguing all bathymetry data in the Australian Region. For convenience this region has been loosely defined as extending from 5°S to 80°S and 45°E to 180°E. The contents of the Bathymetric Database consists of four datatypes: - Multibeam Echosounder Data (including LADS) - Singlebeam Echosounder Data - Depths from the digitisation of pre-existing maps - "Depths" derived from remote sensing techniques (and produced grids) The dataset described by this metadata record is the Multibeam Echosounder Dataset. It consists of the soundings of a number of multibeam surveys (170 by April 2007), that vary in size from a few km2 to about 250,000 km2 in size. Data coverage of the defined region is not complete. The datasets were collected by a variety of vessels (Australian and foreign) using a range of sensor systems. As a result the original data exist in a variety of raw data formats on a variety of media. These raw data have been archived in a secure repository at GA. For more details, one should access the metadata records for the individual surveys or the report given in the "Additional Metadata" section of this metadata record. All of the raw data have been imported into the CARIS HIPS application and processed using a common workflow. The processed data have then been exported as GSF "day" files (MBSystem format 121) and stored on Unix directories. These files are easily manipulated using most multibeam data applications

Bathymetric map showing geological features with contours in metres. Includes Australian Fishing zone limit, seismic survey lines, petroleum exploration wells, in the Esperance region, including Diamantina Zone (Southern Ocean) Index to adjoining sheets, reliability diagram and locality map. Project coordination by C.R. Johnston, J. Williams, B. Willington ; data compilation D. Jongsma. "A joint project of the Hydrographic Service, RAN, Department of Defence, the Bureau of Resource Sciences and the Australian Geological Survey Organisation".
