South Australian Marine Benthic Habitats

Dataset Number1233
Dataset TitleSouth Australian Marine Benthic Habitats
CustodianData Authority: Department for Environment and Water
Data Provider: Department for Environment and Water

Description

DescriptionInshore benthic habitat mapping of the Adelaide Dolphin Sanctuary, Adelaide Mount Lofty Ranges (AMLR), Yorke Peninsula, Eyre Peninsula, Upper Spencer Gulf, Upper Gulf St Vincent, South East and Kangaroo Island, as part of a wider DEWNR project to map specific areas of the South Australian inshore environments.
UsageTo improve upon existing knowledge, planning and management of inshore benthic habitats, within South Australia.

Data Quality

LineageHabitat boundaries were interpreted from underwater features discernable on ortho-rectified aerial photographs. Year ranges of data capture for the following regionsSELECT 1 FROM DUAL; Adelaide Dolphin Sanctuary 2001-2006, Upper Gulf St Vincent and Upper Spencer Gulf 2005-2007. Adelaide Mt Lofty Ranges(AMLR) 2007-2008 and South East 2009-2010. Field observations and underwater video footage was used to capture the Upper Spencer Gulf and Upper Gulf St Vincent data. The AMLR data was captured from field observations, underwater video footage, acoustic mapping and sidescan sonar. The data sets were combined as part of a DEWNR statewide project. Additional data was captured on Kangaroo Island during 2013 which included field observations and Underwater video footage. This data was added by regional staff using an adapted data schema that now includes species specific information.
CompletenessThis dataset is considered complete.
Positional AccuracyAccuracy ranges from +/- 10m to +/- 20m.
