All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

Quality

Each parameter is assigned a data quality flag as defined below:

Flag 1: Error free
Flag 2: Dubious. Non-specific errors
Flag 3: Known errors exist that can be fixed
Flag 4: Known errors exist that cannot be fixed
Flag 5: No data - not observed
Flag 6: Data in analog format only
