Full description
The Camden Sound (North-West) bathymetry survey was acquired for the Australian Hydrographic Office (AHO) onboard the MV Ocean Dynasty and MV Empress during the period 21 September 2021 – 9 Jan 2022. This was a contracted survey conducted for the Australian Hydrographic Office by MMA Offshore as part of the Hydroscheme Industry Partnership Program. The survey area encompases an area North West of Camden Sound, Western Australia. Bathymetry data was acquired using a Kongsberg EM2040P Mk II and processed using QPS Qimera V2.0.1 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).
