Abstract
Carnarvon Shelf reef polygons were manually digitized from multibeam echosounder datasets collected on marine survey GA0308 in August/September 2008. Reef areas were defined as exposed, hard substrate that are often raised above the surrounding seafloor. They were mapped using bathymetry and backscatter data along with bathymetric derivatives including; slope, hillshaded bathymetry and contours. Features were mapped at a scale of 1:10 000. This dataset is published with the permission of the CEO, Geoscience Australia.

Lineage
This dataset was derived from multibeam echosounder data collected during marine survey GA0308 in August/September 2008. Reef/hard substrate features were manually digitised in ArcGIS 10.2 using hillshaded bathymetry, backscatter and slope datasets. This dataset was produced under the National Environmental Science Program- Project D3 evaluating and monitoring the status of marine biodiversity assets on the continental shelf.
