RV Investigator IN2026_V01: Hydrology Data from Antarctic COOKIES Voyage

Hydrology data from the RV Investigator voyage IN2026_V01, titled 'Cook Ice Ecosystems and Sediments (COOKIES).' The voyage took place between January 02, 2026 and February 25, 2026, departing from and returning to Hobart. Samples were collected from Niskin bottles at various depths during CTD deployments and analyzed for salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, and ammonium.

Use Cases

• Modeling nutrient distributions based on phosphate, silicate, nitrate, and nitrite measurements.
• Analyzing dissolved oxygen levels relative to salinity and temperature profiles.
• Studying marine biogeochemical processes in Antarctic waters using the suite of analyzed parameters.

Strengths

• Data has been processed and quality-controlled.
• Archived at the CSIRO National Collections and Marine Infrastructure Information and Data Centre (IDC) in Hobart.

Limitations

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