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.Maintenance and Update Frequency: asNeededStatement: Version 1&rft.creator=Siwabessy, P.J.W. &rft.creator=Smit, N. &rft.creator=Atkinson, I. &rft.creator=Dando, N. &rft.creator=Harries, S. &rft.creator=Howard, F.J.F. &rft.creator=Li, J. &rft.creator=Nicholas, W.A. &rft.creator=Potter, A. &rft.creator=Radke, L.C. &rft.creator=Tran, M. &rft.creator=Williams, D. &rft.creator=Whiteway, T. &rft.date=2016&rft.coverage=westlimit=130.5135; southlimit=-12.4309; eastlimit=131.9855; northlimit=-12.1178; projection=WGS 84 / UTM zone 52S&rft.coverage=westlimit=130.5135; southlimit=-12.4309; eastlimit=131.9855; northlimit=-12.1178; projection=WGS 84 / UTM zone 52S&rft_rights=&rft_rights=Creative Commons Attribution 4.0 International Licence&rft_rights=CC-BY&rft_rights=4.0&rft_rights=http://creativecommons.org/licenses/&rft_rights=WWW:LINK-1.0-http--link&rft_rights=Australian Government Security ClassificationSystem&rft_rights=https://www.protectivesecurity.gov.au/Pages/default.aspx&rft_rights=WWW:LINK-1.0-http--link&rft_rights=Creative Commons Attribution 4.0 International Licence http://creativecommons.org/licenses/by/4.0&rft_subject=oceans&rft_subject=GA Publication&rft_subject=Record&rft_subject=marine&rft_subject=coastal waters&rft_subject=marine biodiversity&rft_subject=multibeam&rft_subject=sedimentology&rft_subject=geochemistry&rft_subject=backscatter&rft_subject=NT&rft_subject=EARTH SCIENCES&rft_subject=Published_External&rft.type=dataset&rft.language=English Access the data

Brief description

This report provides a description of the activities completed during the Outer Darwin Harbour Mapping Survey, from 28 May and 23 June 2015 on the RV Solander (Survey GA0351/SOL6187). 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.
