Description
Summary:This layer group describes multibeam echosounder data collected on RV Investigator voyage IN2023_V01 titled "Antarctic Bottom Water Production in the past: Records from marine sediments, Cape Darnley, East Antarctica". The voyage took place between 25th January, 2023 and 2nd March, 2023 departing from Henderson's AMC Wharf (WA) and arriving in Hobart (TAS). This study had two main scientific objectives i) to understand past changes in Antarctic Bottom Water (AABW) production using long sediment cores from the continental slope over multiple warm periods during the Pleistocene; ii) develop an improved bathymetry model to support oceanographic modelling of AABW pathways. This dataset is published with the permission of CSIRO. Not to be used for navigational purposes. The dataset contains bathymetry grids of 10m to 210m resolution of Antarctic shelf, including area near Cape Darnley produced from the processed EM122 and EM710 bathymetry data. ...
