Brief description

Tasmania (Barrett, Lucier - TAFI; Johnson, Ling - UTAS) The primary objective of this work was to describe biological assemblages associated with rocky reef systems in deep shelf waters on the Tasman Peninsula in SE Tasmania and in the Huon, Freycinet and Bruny Island Marine Protected Areas (MPA), providing a record of community composition at or near the time of designation of these MPAs. Detailed multibeam sonar bathymetry data were previously collected by Geoscience Australia (GA) to provide high-resolution digital elevation maps of the study areas. These maps were used to determine suitable AUV survey locations. At each location, multiple reefs were surveyed at a range of depths from approximately 50 m to 100 m depth. Dive profiles were designed to provide sufficient replication to quantitatively determine abundances of key species/features within depth strata, within reefs, between reefs (km to 100 km scale), and between differing levels of reef complexity. The AUV deployments were part of a multi-disciplinary experimental program to analyse the covariance of co-located fine-resolution seabed habitat data, provided by the EM3002 multibeam sonar coverage, and biological datasets collected at similar spatial scales by Remotely Operated Vehicles (ROVs), Baited Remote Underwater Video systems, towed video and the AUV.

Scallop fisheries at Maria Island, Freycinet MPA, St Helens urchin barrens, Bruny Island MPA; 18 dives over 7 days of operations.
