Description
CSIRO's Marine National Facility RV Investigator voyage IN2026_V01, titled 'Cook Ice Ecosystems and Sediments (COOKIES)', collected a wide array of oceanographic, atmospheric, and biological data between January 02 and February 25, 2026. The End of Voyage archive includes measurements from over 40 instruments, such as CTD profiles, multibeam echosounders, greenhouse gas analyzers, sediment corers, and environmental DNA samples. This integrated dataset supports research on Southern Ocean ecosystems, seafloor geology, and air-sea interactions in the Antarctic region.
Use Cases
Mapping seafloor bathymetry and sub-bottom structure based on multibeam echosounder and sub-bottom profiler data.
Studying ocean currents and water column properties using data from lowered ADCP, CTD, and thermosalinograph instruments.
Analyzing atmospheric composition and aerosol physics with measurements from greenhouse gas analyzers, cloud condensation nuclei counters, and nephelometers.
Investigating benthic ecosystems and sedimentology through samples collected by multi-corer, kasten corer, and giant piston corer, complemented by deep-towed camera video.
Monitoring marine wildlife populations via systematic observations of seabirds, cetaceans, and seals.
Strengths
Integrates data from over 40 distinct instruments, providing a highly multidisciplinary observational record.
Covers a specific and temporally bounded research voyage from January 02 to February 25, 2026, ensuring contextual coherence.
Includes both standard ('regular') and voyage-specific measurements, such as eDNA and trace metal sampling, tailored to the COOKIES research objectives.
Curated and permanently archived by the authoritative CSIRO National Collections and Marine Infrastructure Information and Data Centre.
Limitations
Critical metadata such as row count, file size, specific column names, and license information are not provided in the available sources.
The dataset's structure and access details for the raw data archive are not fully described, requiring users to follow external links.
Data from multiple identical platform entries show a minor conflict in the 'last updated' timestamp (2026-03-25 vs. 2026-04-26).
