This paper describes a two week deployment of the Autonomous Underwater
Vehicle (AUV) Sirius on the Tasman Peninsula in SE Tasmania and in the
Huon Marine Protected Area (MPA) to the South West of Hobart. The objective of
the deployments described in this work were to document biological assemblages
associated with rocky reef systems in shelf waters beyond normal diving depths. At
each location, multiple reefs were surveyed at a range of depths from approximately
50 m to 100 m depth. We illustrate how the AUV based imaging complements benthic
habitat assessments to be made based on the ship-borne swath bathymetry. Over
the course of the 10 days of operation, 19 dives were undertaken with the AUV
covering in excess of 70 linear kilometers of survey and returning nearly 160,000
geo-referenced high resolution stereo image pairs. These are now being analysed to
describe the distribution of benthic habitats in more detail.
