After the addition of the POSMV Wavemaster, horizontal precision was increased to be better than +/- 0.1 m. Data is collected using a pole mounting and are tide, sound velocity and motion corrected and are accurate to the sub-metre level (DGPS/POSMV).&rft.creator=Office of Environment and Heritage (OEH), New South Wales Government &rft.date=2016&rft.coverage=uplimit=2228; downlimit=100&rft.coverage=uplimit=2228; downlimit=100&rft_rights=&rft_rights= http://creativecommons.org/licenses/by/4.0/&rft_rights=https://licensebuttons.net/l/by/4.0/88x31.png&rft_rights=WWW:LINK-1.0-http--related&rft_rights=License Graphic&rft_rights=Creative Commons Attribution 4.0 International License&rft_rights=http://creativecommons.org/international/&rft_rights=WWW:LINK-1.0-http--related&rft_rights=WWW:LINK-1.0-http--related&rft_rights=License Text&rft_rights=The citation in a list of references is: State of New South Wales and Office of Environment and Heritage (OEH) [year-of-data-download], [Title], [data-access-url], accessed [date-of-access].&rft_rights=Creative Commons Attribution 4.0 International License http://creativecommons.org/licenses/by/4.0&rft_subject=oceans&rft_subject=WATER DEPTH&rft_subject=EARTH SCIENCE&rft_subject=OCEANS&rft_subject=BATHYMETRY/SEAFLOOR TOPOGRAPHY&rft_subject=SEAFLOOR TOPOGRAPHY&rft_subject=ACOUSTIC SCATTERING&rft_subject=OCEAN ACOUSTICS&rft_subject=MARINE HABITAT&rft_subject=BIOSPHERE&rft_subject=AQUATIC ECOSYSTEMS&rft_subject=CORAL REEFS&rft_subject=COASTAL PROCESSES&rft_subject=Global / Oceans | Pacific Ocean&rft_subject=Regional Seas | Tasman Sea&rft_subject=Countries | Australia&rft_subject=States, Territories (Australia) | New South Wales&rft_subject=Field Surveys | Underwater Surveys&rft_subject=Physical Oceanography&rft_subject=research vessel&rft_subject=Sea-floor depth below surface of the water body&rft_subject=multi-beam echosounders&rft.type=dataset&rft.language=English Access the data

Brief description

Data products from multi-beam bathymetry surveys carried out by the New South Wales Office of Environment and Heritage (OEH). Surveys were conducted in and around NSW Coastal and State Waters, using a mounted GeoAcoustics Geoswath 125KHZ Interferometric sidescan sonar system, by the HABMAP program. The HABMAP program, which was initiated to provide fine scale benthic habitat information for NSW State Waters, initiated surveys to provide a minimum of 5 x 5m bin scale bathymetric and backscatter layers for use in GIS applications. Products include fine-scale bathymetric and relative acoustic backscatter data in several formats. For each survey there is also a "scientific rigour" document describing the origin and processing of the data, and files showing the geographic coverage of the survey (ESRI shapefile and Google KMZ formats).
