The survey was a collaboration between the Australian Institute of Marine Science (AIMS) and Geoscience Australia (GA) aboard RV Solander, as part of the Hub's Surrogates Program. The purpose of field surveys in the Surrogates Program is to collect high-quality, accurately co-located data to enable the robust testing of a range of physical parameters as surrogates of patterns of benthic biodiversity in strategically selected, spatially discrete areas that are representative of much broader benthic environments. The report describes the methods employed in the survey and the datasets collected. Additional processing of most of the physical data (wave and current measurements, multibeam sonar bathymetry and backscatter, sediment grab samples, acoustic sediment profiles) and biological data (towed underwater video and stills photography, bottom sediment samples, near-bottom plankton samples) collected is required before comparative analysis between the data sets can commence. However, a number of initial interpretations of the physical data have been made and examples of the types of biota encountered in the towed video and stills photography and initial interpretations of the benthic communities encountered, are provided. The survey was focussed on three strategically selected study areas on the southern Carnarvon Shelf at Mandu, Point Cloates and Gnaraloo. A small additional area was also examined near the Muiron Islands, in the mouth of Exmouth Gulf, at the end of the survey. {"type": "Polygon", "coordinates": [[[113.1894, -23.9058], [113.9039, -23.9058], [113.9039, -22.0552], [113.1894, -22.0552], [113.1894, -23.9058]]]} 113.1894 113.9039 -23.9058 -22.0552 AU-WA CERF Earth Sciences GA Publication Published_External Record bathymetry coasts habitat marine seabed sedimentology Download the Record (pdf) documentDigital Download the Record (pdf) PDF Unnamed resource documentDigital HTML
