Geoscience Australia defines a sample as a feature observed, measured or collected in the field. A specimen is a physical individual sample collected during the field work. This data set represents a subset of all Sampling data held by Geoscience Australia that have been collected as part of drilling activities (ie relate to Australian Boreholes). The data will be utilised by other data domains by providing Sampling context to various Observation & Measurement data.

Jervis Bay Reef Polygons were digitised from the Multibeam bathymetry datasets of Jervis Bay. Reef areas were defined as seabed hard substrate that are often raised from the surroundings flat sedimentary seabed. They were identified and mapped relatively easily on hillshaded bathymetry layers.
