Applications to access voyage documentation by non-CSIRO participants can be made via [e-mail] All processed data from this voyage are made publicly available through the MNF Data Trawler (in the related links)\nLineage: Original field data. The raw EOV data archive was transferred to the CSIRO NCMI Information and Data Centre in Hobart. \n\nA 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.\n\nAvailable 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.
