Voyage 2 of the 2021-2022 season - Processed Bathymetric Datasets

Published: 2026-07-27

This dataset contains the Multibeam Echosounder data from Voyage 2 2021-22 collected during RSV Nuyina’s maiden voyage to Antarctica. Data was collected in transit between Hobart, Davis station, Casey station and Vanderford Glacier for the purpose of seabed classification, to improve charting and navigational safety. This dataset was processed to remove any noise, corrected to Earth Gravitational Model 2008 (EGM2008), then exported as a 128m x 128m shapefile and a 128m x 128m depth banded geotiff provide an accurate depiction of the depth of water and seabed. For different resolution surfaces and processed sounding data in GSF/XYZ formats please contact the Australian Antarctic Divisions Hydrographic Data Coordinator at roek.dyer@aad.gov.au. Dataset is not to be used for navigation.
