This survey was a collaboration between Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and Department of Land Resource Management (Northern Territory Government) and the first of four surveys in the Darwin Harbour Seabed Habitat Mapping Program. This 4 year program (2014-2018) aims to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline information and developing thematic habitat maps that will underpin future marine resource management decisions. The program was made possible through funds provided by the INPEX-led Ichthys LNG Project to Northern Territory Government Department of Land Resource Management, and co-investment from Geoscience Australia and Australian Institute of Marine Science. The specific objectives of the Outer Darwin Harbour Marine Survey GA0351/SOL6187 were to: <ol> <li>Obtain high resolution geophysical (bathymetry) data for outer Darwin Harbour, including Shoal Bay;</li> <li>Characterise substrates (acoustic backscatter properties, grainsize, sediment chemistry) for outer Darwin Harbour, including Shoal Bay; and</li> <li>Collect tidal data for the survey area.</li> </ol> Data acquired during the survey included: 720 km2 multibeam sonar bathymetry and acoustic backscatter; 96 sampling stations collecting seabed sediments, underwater photography and video imagery and oceanographic information including tidal data and 54 sound velocity profiles. {"type": "Polygon", "coordinates": [[[130.5135, -12.4309], [131.9855, -12.4309], [131.9855, -12.1178], [130.5135, -12.1178], [130.5135, -12.4309]]]} 130.5135 131.9855 -12.4309 -12.1178 Earth Sciences GA Publication NT Published_External Record backscatter coastal waters geochemistry marine marine biodiversity multibeam sedimentology Download the Record (docx) documentDigital Download the Record (docx) DOCX Download the Record (pdf) documentDigital Download the Record (pdf) PDF Link to collection record documentDigital Link to collection record HTML Unnamed resource documentDigital HTML
