The survey, undertaken as part of the Department of Industry and Science's National CO2 Infrastructure Plan (NCIP), aimed to identify and characterise indicators of natural hydrocarbon or fluid seepage that may indicate compromised seal integrity in the region. The survey was conducted in three legs aboard the New Zealand research vessel RV Tangaroa, and included scientists and technical staff from GA, the NZ National Institute of Water and Atmospheric Research Ltd. (NIWA) and Fugro Survey Pty Ltd. Shipboard data (survey ID GA0345) collected included multibeam sonar bathymetry and backscatter over 12 areas (A1, A2, A3, A4, A6b, A7, A8, B1, C1, C2b, F1, M1) totalling 455 km2 in water depths ranging from 90 - 430 m, and 611 km of sub-bottom profile lines. Seabed samples were collected from 48 stations and included 99 Smith-McIntyre grabs and 41 piston cores. An Autonomous Underwater Vehicle (AUV) (survey ID GA0346) collected higher-resolution multibeam sonar bathymetry and backscatter data, totalling 7.7 km2, along with 71 line km of side scan sonar, underwater camera and sub-bottom profile data. Twenty two Remotely Operated Vehicle (ROV) missions collected 31 hours of underwater video, 657 still images, eight grabs and one core. This data package brings together a suite of datasets and documents which describe the seabed environments and shallow geology of the Caswell Sub-basin, Browse Basin, Western Australia. {"type": "Polygon", "coordinates": [[[122.3883, -14.2865], [124.6521, -14.2865], [124.6521, -12.8678], [122.3883, -12.8678], [122.3883, -14.2865]]]} 122.3883 124.6521 -14.2865 -12.8678 Data Package Exclusive Economic Zone Marine Geoscience Published_External datasets geological storage of CO2 marine environmental baselines marine survey Autonomous Underwater Vehicle (AUV) still images documentDigital Autonomous Underwater Vehicle (AUV) still images HTML Total oxygen uptake and TCO2 release from core incubation experiments on marine sediments documentDigital Total oxygen uptake and TCO2 release from core incubation experiments on marine sediments HTML Sediment oxygen demand in seabed sediments documentDigital Sediment oxygen demand in seabed sediments HTML Total sediment metabolism, bulk carbonate, mineral specific surface area, major and trace elements and carbon and nitrogen concentrations and isotopes of seabed sediments documentDigital Total sediment metabolism, bulk carbonate, mineral specific surface area, major and trace elements and carbon and nitrogen concentrations and isotopes of seabed sediments HTML Chlorophyll a, b, c and Pheaophytin a concentrations in seabed sediments documentDigital Chlorophyll a, b, c and Pheaophytin a concentrations in seabed sediments HTML A Marine Survey to Investigate Seal Integrity Between Potential CO2 Storage Reservoirs and Seafloor documentDigital A Marine Survey to Investigate Seal Integrity Between Potential CO2 Storage Reservoirs and Seafloor HTML Porosity and Chlorins documentDigital Porosity and Chlorins HTML High Resolution Bathymetry Grids documentDigital High Resolution Bathymetry Grids HTML Organic Geochemistry of Core Sediments documentDigital Organic Geochemistry of Core Sediments HTML Shipboard Multibeam Backscatter Grids documentDigital Shipboard Multibeam Backscatter Grids HTML High-resolution Autonomous Underwater Vehicle (AUV) Backscatter Grids documentDigital High-resolution Autonomous Underwater Vehicle (AUV) Backscatter Grids HTML p-rock (Probability of Rock) Grids documentDigital p-rock (Probability of Rock) Grids HTML Autonomous underwater Vehicle (AUV) Sub-bottom Profiler Data documentDigital Autonomous underwater Vehicle (AUV) Sub-bottom Profiler Data HTML Shipboard Sub-bottom Profiler Data documentDigital Shipboard Sub-bottom Profiler Data HTML Autonomous Underwater Vehicle (AUV) Sidescan Sonar Data documentDigital Autonomous Underwater Vehicle (AUV) Sidescan Sonar Data HTML Standard Multi-Sensor Core Logger Data documentDigital Standard Multi-Sensor Core Logger Data HTML High-resolution Imagery of Piston Cores documentDigital High-resolution Imagery of Piston Cores HTML Sediment Data documentDigital Sediment Data HTML Remotely Operated Vehicle (ROV) imagery documentDigital Remotely Operated Vehicle (ROV) imagery HTML Browse Basin Marine Survey, 2014 (GA-0345,GA-0346 and TAN1411) - High Resolution Bathymetry Grids WMS documentDigital Browse Basin Marine Survey, 2014 (GA-0345,GA-0346 and TAN1411) - High Resolution Bathymetry Grids WMS HTML Unnamed resource documentDigital HTML
