Abstract

<div>The Zeehan and Franklin Marine Parks, West Coast Tasmania&nbsp;Bathymetry Acquisition was acquired by CSIRO onboard the TV Bluefin between 22 Feb 2022 and 21 Mar 2022, using a Kongsberg EM2040C. This was a contracted survey conducted for the Institute for Marine and Antarctic Studies (IMAS), University of Tasmania, to conduct a multibeam survey encompasing the Zeehan and Franklin Marine Parks for Parks Australia. Bathymetry data was processed using QPS Qimera and Caris Hips & Sips processing software. The dataset was then exported as a 2m resolution, 32 bit floating point GeoTIFF grid of the survey area. A detailed report on the survey is provided in: Hydrographic Survey of Zeehan and Franklin Marine Parks, West Coast Tasmania (https://figshare.utas.edu.au/articles/report/Hydrographic_Survey_of_Zeehan_and_Franklin_Marine_Parks_West_Coast_Tasmania/23171318).</div><div>This dataset is not to be used for navigational purposes.</div>
