RV Investigator Voyage IN2026_V01: Marine and Atmospheric Data from Antarctic Expedition

The RV Investigator voyage IN2026_V01, titled 'Cook Ice Ecosystems and Sediments (COOKIES)', took place from January 02 to February 25, 2026. The archive contains data from over 40 instruments, including ADCPs, greenhouse gas analyzers, echosounders, corers, and environmental DNA samplers. It is curated by the CSIRO 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.
• Analyzing marine biodiversity and ecosystem health based on Environmental DNA (eDNA) and wildlife observation records.
• Studying sediment composition and paleoclimate records based on core samples from the Multi-corer and Giant Piston Corer.
• Investigating atmospheric aerosols and cloud formation based on Cloud Condensation Nuclei (CCN) and particle size spectrometer data.
• Mapping seafloor topography and sub-bottom geology based on Multibeam Echosounder and Sub-bottom Profiler data.

Strengths

• Data collected during a 55-day dedicated research voyage in the Antarctic region.
• Includes measurements from over 40 distinct instruments covering oceanographic, atmospheric, biological, and geophysical domains.
• Archive is permanently hosted and curated by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.

Limitations

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