Bynoe Harbour Habitat Mapping Bathymetry Survey (SOL6432/GA4452)

This resource contains multibeam bathymetry data collected as part of the Darwin and Bynoe Harbour Habitat Mapping Project undertaken by Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Northern Territory Government (Department of Environment and Natural Resources). The data were acquired during the period from 3 to 27 May 2016 on the RV Solander (survey SOL6432/GA04452). This project was made possible through offset funds provided by INPEX-led Ichthys LNG Project to Northern Territory Government Department of Environment and Natural Resources, and co-investment from Geoscience Australia and Australian Institute of Marine Science. The intent of this four year (2014-2018) project is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps that underpin marine resource management decisions. The specific objectives of the survey were to:

Obtain high-resolution geophysical (multibeam bathymetry) data for Bynoe Harbour;

Characterise seabed substrates (multibeam acoustic backscatter properties, seabed sediment grainsize, sediment chemistry) for Bynoe Harbour; and

Collect tidal data for the survey area. Data acquired during the survey included: multibeam sonar bathymetry and acoustic backscatter; physical samples of seabed sediments, seabed still images and video footage of grab sample locations, and oceanographic information including tidal data and water column sound velocity profiles.

This V1 dataset contains two 2m resolution 32-bit geotiff of the SOL6432 survey area produced from the processed Kongsberg EM2040C bathymetry data.
