Seafloor Mapping of the South-east Region and Adjacent Waters - AUSTREA Final Report: Southern Macquarie Ridge

As part of the Australian Government South-east Regional Marine Plan, Geoscience Australia and the National Oceans Office collaborated through the AUSTREA marine survey to map and interpret the seafloor character over the southern Macquaire Ridge. Multibeam swath bathymetry and reflectivity, along with high-resolution seismic, reveal a complex morphology and sedimentation patterns largely influenced by plate processes and ocean-bottom current effects.
