From 29 January to 24 March 2021, the RV Investigator research voyage IN2021_V01 collected acoustic and krill data off the Australian Antarctic Territory. The dataset contains approximately 460 hours of underwater recordings from 251 deployed DIFAR sonobuoys. It was created by the CSIRO Marlin Data Catalogue as part of the TEMPO survey to quantify krill abundance and study predator observations.
File formats are listed as PNG and HTML, which may indicate metadata or visualization files rather than the primary acoustic data; the raw data format is not specified.
