Abstract

<div>The Bass Pyramid to Wright Block&nbsp;bathymetry survey was acquired for the Australian Hydrographic Office (AHO) during the period 16 Oct 2023 – 10 Jan 2024. This was a contracted survey conducted for the Australian Hydrographic Office as part of the Hydroscheme Industry Partnership Program. The survey area encompasses an area in Bass Pyramid to Wright Block. Bathymetry data was acquired using a Kongsberg EM2040-07, 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>
