Brief description

This resource includes bathymetry data acquired during the Recherche Archipelago 2003 bathymetry survey collected using a Reson SeaBat 8125 multibeam sonar system by Curtin University of Technology (CUT) on the charter vessel Firebird during the period 29th October – 6th November 2003. The survey was undertaken as a collaborative project between CUT and the University of Western Australia (UWA) under the Coastal Water Habitat Mapping (CWHM) Project within Coastal Cooperative Research Centre Program. The purpose of the project was to build baseline information for benthic habitats within the study area. This V1 dataset contains a 2m resolution 32-bit floating point geotiff file of the Recherche Archipelago bathymetry, derived from the processed Reson SeaBat 8125 bathymetry data, using CARIS HIPS and SIPS software.
