RV Investigator COOKIES Voyage: Oceanographic and Atmospheric Data from Antarctic Waters

An End of Voyage archive from the RV Investigator's IN2026_V01 'Cook Ice Ecosystems and Sediments' expedition. The voyage occurred between January 02, 2026 and 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

• Modeling ocean currents and water column properties based on ADCP and CTD data.
• Analyzing marine biodiversity and ecosystem structure based on eDNA, fisheries echosounder, and wildlife observation data.
• Studying sediment composition and geological history based on core samples from the multi-corer, kasten corer, and giant piston corer.
• Investigating atmospheric composition and climate interactions based on greenhouse gas, aerosol, and cloud condensation nuclei measurements.
• Mapping seafloor bathymetry and sub-bottom profiles based on multibeam echosounder and sub-bottom profiler data.

Strengths

• Voyage-specific timeframe is precisely defined from January 02 to February 25, 2026.
• Description lists over 30 distinct instrument types, suggesting broad measurement coverage.
• Data is archived by CSIRO's National Collections and Marine Infrastructure, a recognized authority.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
