Description
Over 40 distinct oceanographic and atmospheric instruments collected data during the 55-day COOKIES voyage from Hobart to the Antarctic region in early 2026. The archive includes regular measurements like CTD profiles, multibeam echosounder bathymetry, and greenhouse gas analysis, alongside voyage-specific collections such as sediment cores, eDNA samples, and wildlife observations. Data is curated by CSIRO's National Collections and Marine Infrastructure Information and Data Centre and archived at the CSIRO Data Access Portal.
Use Cases
Modeling ocean currents and water column properties based on ADCP and CTD data.
Mapping seafloor topography and sub-bottom geology based on multibeam echosounder and sub-bottom profiler data.
Analyzing atmospheric composition and aerosol interactions based on greenhouse gas analyzers, particle counters, and nephelometer data.
Studying marine biodiversity and ecosystem structure based on eDNA, fisheries echosounder, and wildlife observation data.
Investigating sediment history and biogeochemistry based on multi-corer, kasten corer, and giant piston corer samples.
Strengths
Data collected over a 55-day continuous voyage from January 2 to February 25, 2026.
Instrument suite includes over 40 distinct sensors for ocean, atmosphere, and seafloor measurement.
Permanent archive maintained 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 dataset size are unknown, which may limit suitability assessment.
