RV Investigator Antarctic Voyage Instrumentation Archive

End-of-voyage data archive from the RV Investigator's IN2026_V01 expedition, titled 'Cook Ice Ecosystems and Sediments (COOKIES)'. The voyage occurred from January 2 to February 25, 2026, departing from and returning to Hobart. The archive is curated by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.

Use Cases

• Analyze ocean current profiles using data from the Lowered ADCP (LADCP) and Acoustic Doppler Current Profiler.
• Model cloud formation processes with Cloud Condensation Nuclei (CCN) counter and Condensation Particle Counters (CPC) data.
• Study marine sediment composition and paleoclimate from cores collected by the Multi-corer, Kasten corer, and Giant Piston Corer (GPC).
• Track greenhouse gas fluxes in the Southern Ocean using Picarro Greenhouse Gas Analysers and pCO2 sensor readings.
• Map seafloor bathymetry and sub-bottom structures with Multibeam Echosounder (EM712, EM124, EM2040) and Sub-bottom Profiler (SBP29) data.

Strengths

• Voyage employed over 40 distinct scientific instruments for regular and voyage-specific measurements.
• Data collection spanned a 55-day period in the Antarctic region during the austral summer of 2026.
• Archive is permanently hosted and curated by a national research organization (CSIRO).

Limitations

• Specific data volume, row counts, and column details are unknown.
• Raw data access may be restricted to voyage participants and processors initially.
• Data from specialized instruments like the Deep Towed Camera (DTC) or eDNA samples may have limited spatial or temporal coverage.
