Brief description
The Booby Island to D'Arcole Islands, Bonaparte Archipelago bathymetry survey was acquired for the Australian Hydrographic Office (AHO) onboard the MV Offshore Solution and MV Special Order during the period 15 September 2022 – 26 November 2022. This was a contracted survey conducted for the Australian Hydrographic Office by Guardian Geomatics as part of the Hydroscheme Industry Partnership Program. The survey area encompases an area in Booby Island to D'Arcole Islands, Bonaparte Archipelago, Western Australia. Bathymetry data was acquired using a Kongsberg EM2040P and a Kongsberg EM2040-07, and processed using CARIS HIPS & SIPS processing software. The dataset was then exported as a 30m resolution, 32 bit floating point GeoTIFF grid of the survey area.
This dataset is not to be used for navigational purposes.

Processing methodology:
This dataset was produced using CARIS HIPS & SIPS as follow:
1. Processed in accordance with HIPP SOR 2020v 1.2 using CUBE techniques, 1m and 2m CUBE surfaces generated as the final L3 product (a gridded surface derived from cleaned point data).
2. Data was provided to Geoscience Australia for publication.
3. The final processed grid was exported as a 32-bit floating point Geotiff at 30 m resolution, referenced to MSL, WGS 84 (EPSG:4326).
