This record describes the Wildlife on Voyage (WoV) data collected on Investigator voyage IN2023_V02, titled: "Gigantic submarine landslide offshore western Tasmania: risk mitigation for shelf-derived tsunami in Australia." The voyage took place between March 24, 2023 and April 30, 2023 (AEST), departing from Hobart and returning to Hobart. These surveys were conducted alongside Marine Mammal Observer (MMO) duties associated with seismic operations. There were two survey protocols: Continuous (which were performed when seismic operations required MMOs on watch for the entire survey period); and structured snapshots. The collected data were processed (quality-controlled), and subsequently archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC). Please note: besides marine mammals and seabirds, the dataset also includes a few tuna and shark observations. Additional information regarding this dataset may be found in the data package README file and the associated publication: Viola, B., Puskic, P., Corney, S. et al. A quantitative assessment of continuous versus structured methods for the detection of marine mammals and seabirds via opportunistic shipboard surveys.
