Abstract
The map provides a visual representation of the gravel content of seabed sediments expressed as a weight percentage. The data are represented from 0 to 100%. The data on which this map is based were compiled from Geoscience Australia's marine sediment database (MARS - http://www.ga.gov.au/oracle/mars/).

Lineage
Marine sediment sample information within the Australian Maritime Jurisdiction was sourced by Geoscience Australia from Australian and international research groups, Government bodies, private corporate entities, and published/unpublished reports. This information was then used to populate a National Marine Sediments Database (MARS - http://www.ga.gov.au/oracle/mars/). MARS is an Oracle database that has been developed by Geoscience Australia in line with ANZLIC data standards. The point data is from seabed samples where gravel content for the entire sample has been measured or determined through standard laboratory analysis methods, and was exported from MARS to ARC/GIS for the generation of maps. The point data was then interpolated using the "inverse distance squared weighted" algorithm to create the raster data presented here.
