IN2026_V01 COOKIES Voyage: Oceanographic and Atmospheric Measurements from RV Investigator

January 02, 2026 to February 25, 2026 data archive from the RV Investigator voyage IN2026_V01, titled 'Cook Ice Ecosystems and Sediments (COOKIES).' The voyage departed from and returned to Hobart, collecting data on ocean currents, water chemistry, atmospheric conditions, and marine life. The archive is curated by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.

Use Cases

• Modeling ocean currents and water column structure based on Acoustic Doppler Current Profiler (ADCP) and CTD data.
• Studying marine carbon cycles and greenhouse gases based on pCO2 and Picarro analyser measurements.
• Analyzing seabed composition and geology based on Multibeam Echosounder and Sub-bottom Profiler data.
• Investigating atmospheric aerosol and cloud formation processes based on Cloud Condensation Nuclei and particle counter data.
• Cataloging marine wildlife distribution based on Fisheries Echosounder and visual wildlife observation records.

Strengths

• Voyage-specific measurements include Environmental DNA (eDNA), core sampling, and deep-towed camera data for ecosystem analysis.
• Regular measurements cover a wide range of atmospheric and oceanic parameters, including radon, ozone, and photosynthetically active radiation.
• Data is permanently archived and made publicly available through the CSIRO Data Access Portal and MNF Data Trawler.

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.
