AU 420 Norfolk Island Nearshore and Coastal Area Bathymetry Acquisition (20210019S)

The Norfolk Island Nearshore and Coastal Habitat Mapping was acquired by Ocean Infinity Pty Ltd onboard the M/V Offshore Solution from the 21st to the 24th July 2021, using a Kongsberg EM2040 Mark II. This survey was part of the Norfolk Island Nearshore and Coastal Habitat Mapping project in partnership with Deakin University’s Marine Mapping Group, University of Wollongong, Tellus4D Geoimaging, University of Newcastle, University of New South Wales, University of Tasmania and Geoscience Australia to obtain high resolution bathymetric grid (1m) and to define the morpho-bathymetry of the survey area based on the bathymetric grid and derived products such as slope aspect map, ruggedness map, bathymetry position index and backscatter map. This dataset contains a 1m-resolution 32-bit floating point GeoTIFF file of the bathymetry in the study area, derived from the processed EM2040 Mark II bathymetry data, using Qimera and CARIS HIPS and SIPS software.
