IN2018_V08 Tasman Sea Bathymetry 10m - 210m Multi-resolution AusSeabed products

This layer group describes multibeam echosounder data collected on RV Investigator voyage IN2018_V08 titled "The Balleny mantle plume: key role in Tasmania-Antarctic breakup?". The voyage took place between December 27, 2018 and January 10, 2019, departing from Hobart (TAS) and arriving in Hobart (TAS).

The purpose of this voyage was to test the hypothesis that the Balleny Plume played a significant role in the plate tectonic breakup between Tasmania and Cape Adare, Antarctica, and also investigate the plume’s influence on the bathymetric evolution of the Tasman Gateway and related onset of the Antarctic Circumpolar Current.

The dataset contains bathymetry grids of 10m to 210m resolution of the Tasman Sea produced from the processed EM122 and EM710 bathymetry data.
