Towed Video transects + Digital StillsStereo BRUVSMultibeamSmith And McIntyre sediment grabsPanda Cam (drop cam)CTD A seabed biodiversity survey was conducted north of Darwin during an 18 day voyage, 13 September -1 October 2015, on the RV Solander. Areas identified for assessment included two mid-shelf regions and three submerged shoals. Multibeam and towed video were used at all locations to map the seabed and classify seabed habitats. At the shoals additional sampling of biodiversity, specifically the fish communities, was undertaken using sBRUVS.The mid-shelf locations were separate areas along a potential cross-shelf pipeline route from the Barossa field to Darwin. The southernmost of these was to the west of Cape Helvetius, at the southwest corner of Bathurst Island. The second area was midway to the shelf break, adjacent to and off the western side of Goodrich Bank. Evans and Tassie Shoals, lying further northwest on the outer shelf, were selected for investigation as larger submerged shoals, closest to the Barossa field. An initial towed video inspection was also undertaken at the much smaller Blackwood Shoal, lying a few kilometres to the west of Evans Shoal. In total the survey sampled in five principle locations, consisting of Evans, Tassie and Blackwood Shoals, open shelf adjacent to Goodrich Bank and open shelf adjacent to Cape Helvetius.

Towed Video transects + Digital StillsStereo BRUVSMultibeamCTD This biological survey will provide targeted benthic habitat and fish biodiversity information for six key areas associated with a) potential pipeline routes b) potential sensitive receptor habitats outside the Oceanic Shoals Commonwealth Marine Protected Area c) potential sensitive receptor habitats within the Oceanic Shoals Commonwealth Marine Protected Area. The biological survey will use standardised methods so that data collected can be referenced to, and compared with, other survey data collected on this shelf by AIMS, ConocoPhillips and Geoscience Australia.

Geoscience Australia carried out marine surveys in southeast Tasmania in 2008 and 2009 (GA0315) to map seabed bathymetry and characterise benthic environments through observation of habitats using underwater towed video. Data was acquired using the Tasmania Aquaculture and Fisheries Institute (TAFI) Research Vessel Challenger. Bathymetric mapping was undertaken in seven survey areas, including: Freycinet Pensinula (83 sq km, east coast and shelf); Tasman Peninsula (117 sq km, east coast and shelf); Port Arthur and adjacent open coast (17 sq km); The Friars (41 sq km, south of Bruny Island); lower Huon River estuary (39 sq km); D Entrecastreaux Channel (7 sq km, at Tinderbox north of Bruny Island), and; Maria Island (3 sq km, western side). Video characterisations of the seabed concentrated on areas of bedrock reef and adjacent seabed in all mapped areas, except for D Entrecastreaux Channel and Maria Island. friars_3m is an ArcGIS layer of the backscatter grid of the Friars islets, south of Bruny Island produced from the processed EM3002 backscatter data of the survey area using the CMST-GA MB Process This dataset is a contribution to the CERF Marine Biodiversity Hub.
