Full 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. This dataset is not to be used for navigational purposes. This dataset is published with the permission of the CEO, Geoscience Australia.Lineage

Statement: While AusSeabed aims to publish data based on the requirements stated in the AusSeabed multibeam guidelines (version 1, https://australian-multibeam-guidelines.github.io), we will also publish interim products (version 0) that are currently available, but have not yet been standardised (version 1). Users should be aware that V1 products will always supersede V0 products. This dataset was produced using CARIS HIPS/SIPS v.11.3.19 and the AusSeabed-recommended processing methodology as follows. 1. A new Caris project was created in conjuction with existing or newly created vessel configuration file(s). 2. TPU and tide were computed and all data were georeferenced (merged) to the EGM2008 vertical datum. 3. An auto-resolution CUBE was generated as a reference surface for data cleaning. 4. An automated data cleaning was undertaken using a surface cleaning method that utilises the reference surface. 5. Further manual cleaning was conducted as required after visual assessment of the auto-cleaned surface. 6. The final grid was produced at a resolution nearest the banded depth resolution based on the auto-resolution estimate provided in Caris. 7. The final processed grid was exported as a 32-bit floating point Geotiff at 2m resolution, referenced to EGM2008.
