Abstract
This dataset contains all multibeam bathymetry data held by Geoscience Australia as of June 2018. It was compiled from data holdings lying within the offshore area of Australia, including international waters, and gridded at 50m. Source information can be found in the associated vector product, AusSeabed Bathymetry Holdings (https://pid.geoscience.gov.au/dataset/ga/116321). This dataset is accessible via clip, zip & ship enabled web mapping service on Geoscience Australia’s Marine data portal, http://marine.ga.gov.au. In future, this product will be delivered dynamically through the AusSeabed portal (in development).<p><p>This dataset is not to be used for navigational purposes.

Lineage
This dataset was created using MBSystem freeware. Pings were extracted to XYZ format from Caris-processed multibeam survey files, gridding each ping into 50m cells for each of the 81 tiles, combined to form the final product. Prior to gridding, data had a despiking filter applied, with a variable data floor imposed to better eliminate outlying spikes. Overlapping data values were averaged during this process, and there has been no interpolation applied in areas of no data. Data may have varying accuracy in shallow water areas. Data is supplied in WGS84 decimal degrees, with depth as positive integer. NOTE: As much of these data have been sourced from various external institutions, there is no guarantee that they are complete, without artifacts, or have been fully or adequately processed. This should be borne in mind when interpreting the data. Not for navigation purposes.
