RV Investigator IN2026_V01: CTD Casts from Antarctic COOKIES Voyage

37 CTD (Conductivity, Temperature, Depth) casts collected by the RV Investigator during the COOKIES voyage from January to February 2026. Data were acquired using a Sea-Bird SBE911 CTD unit with auxiliary sensors and processed by CSIRO's National Collections and Marine Infrastructure. The dataset includes quality-controlled measurements of oceanographic parameters from the Antarctic region.

Use Cases

• Modeling water column structure based on CTD-derived temperature and salinity profiles.
• Analyzing dissolved oxygen dynamics in Antarctic waters based on calibrated sensor data.
• Studying phytoplankton biomass distribution based on Chlorophyll-A and PAR sensor readings.
• Investigating benthic-pelagic coupling based on observations from the Benthic CTD camera.

Strengths

• Data underwent automated QC to remove spikes and out-of-range values.
• Final conductivity calibration had a standard deviation of 0.00128 PSU, meeting a target of better than 0.002 PSU.
• Includes data from 37 separate CTD deployments with consistent sensor use throughout the voyage.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
