Full description
This record describes the End of Voyage (EOV) data archive from the Marine National Facility (MNF) RV Investigator voyage IN2025_V05, titled "Eruption, destruction, and seafloor ecosystem recovery – Tonga's 2022 eruption of the century." The voyage took place between August 10, 2025 and October 01, 2025 (AEST), departing from Hobart and returning to Brisbane.For further information please refer to the voyage documentation links.

The archive for the IN2025_V05 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 [email protected] All processed data from this voyage are made publicly available through the MNF Data Trawler (in the related links)
Lineage
Maintenance and Update Frequency: notPlanned
Statement: Original field data. The raw EOV data archive was transferred to the CSIRO NCMI Information and Data Centre in Hobart.
A manifest file for the final archive was generated (IN2025_V05_manifest_1.0_rawVoyage_cs.txt, 30/10/2025). Stored Volume: 3,036 folders, 338,387 files, 11,329,501,338,569 bytes.
Available paper documents are scanned to 400 dpi PDF and stored at the IDC record storage system. ELOG files are generated as csv-formatted files and archived.
