The RS9401 bathymetry survey, GA0124 was acquired by Geoscience Australia onboard the Australian vessel Rig Seismic from the 12th of January to the 16th of February 1994 using an MR1 (12 kHz) towed sidescan sonar system. The objectives of the RS9401 bathymetry survey was to collect new data in order to update our understanding of the Macquarie Ridge Complex (MRC), located at the boundary between the Pacific and Australian plates. The survey acquired Sidescan/ bathymetry, gravity and 96- channel seismic reflection imaging across the morphologic ridge and trench system. Gravity and magnetic data were collected during the entire survey. This V0 dataset contains three, 128 m resolution 32-bit geotiff of the Macquarie Ridge survey area produced from the processed MR1 bathymetry data. This dataset is not to be used for navigational purposes. This dataset is published with the permission of the CEO, Geoscience Australia.
