title: RV Investigator Voyage IN2023_V01 End of Voyage (EOV) Archive

description: This record describes the End of Voyage (EOV) data archive from the Marine National Facility (MNF) 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 January 25, 2023 and March 2, 2023 (AEST), departing from Fremantle and returning to Hobart.

The archive for the IN2023_V01 EOV raw data is curated by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC) in Hobart, with a permanent archive at the CSIRO Data Access Portal (https://data.csiro.au/), providing access to voyage participants and processors of the data collected on the voyage.

All voyage documentation is available electronically to MNF support via the local network. Applications to access voyage documentation by non-CSIRO participants can be made via data-requests-hf@csiro.au.
