IMOS - AUV SIRIUS, CAMPAIGN: South East Queensland, OCTOBER 2010

SE Queensland – Moreton Island (Babcock): Dive sites were selected inside and outside of a green zone offshore of Moreton Island.  A broad grid was completed at each site and three dense grids completed in each of the depth bands 15‐20m, 20‐25m and 25‐30m.  There was insufficient ship time available to deploy at other sites in the region where kelp has been documented, including in deeper waters and further north. Sites for targeted dredging, sub-bottom profiling and AUV imaging were then selected for detailed study of particular features.

All activities were undertaken during a 21-day cruise aboard the R/V Southern Surveyor, Australia's Marine National Facility operated by CSIRO.

The study of these structures may yield insights regarding potential future sea level changes and their potential impact on sensitive reef areas such as the GBR.
