Published: 2026-07-28

This dataset contains RSV Nuyina’s EM122 and EM712 MBES Multibeam Echosounder data from Voyage 3 2023-24 collected during transit between Hobart, Mawson, Davis, and Casey 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 128m x 128m shapefile and a 128m x 128m depth banded geotiffs to provide an accurate depiction of the depth of water and seabed. For different resolution surfaces please contact the Australian Antarctic Divisions Hydrographic Data Coordinator at roek.dyer@aad.gov.au. Dataset is not to be used for navigation.
