Abstract
A bathymetric survey of Darwin Harbour was undertaken during the period 24 June to 20 August 2011 by iXSurvey Australia Pty Ltd for the Department of Natural Resources, Environment, The Arts and Sport (NRETAS) in collaboration with Geoscience Australia (GA), the Darwin Port Corporation (DPC) and the Australian Institute of Marine Science (AIMS) using GA's Kongsberg EM3002D multibeam sonar system and DPC's vessel Matthew Flinders.

Lineage
The backscatter data were processed using CMST-GA MB Process v12.05.07 software. The fully processed backscatter strengths were corrected for transmission loss and insonification area. The process within the toolbox also involved removal of the system transmission loss, removal of the system model, calculation of the incidence angle and removal of the angular dependence. The grid values are basically the average values of the processed backscatter point data within each grid cell of predefined size, normalised to the backscatter strength at an angle of 40 degrees.
