Abstract

<div>The Cape Leeuwin bathymetry survey was acquired for the Australian Hydrographic Office (AHO) onboard the MV Mermaid Searcher during the period 5 Dec 2022 – 4 Apr 2023. 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 in Cape Leeuwin, WA. Bathymetry data was acquired using a Kongsberg EM2040P, and processed using CARIS HIPS and SIPS processing software. The dataset was then exported as a 30m resolution, 32 bit floating point GeoTIFF grid of the survey area.</div><div>This dataset is not to be used for navigational purposes.</div>
