RV Investigator IN2026_V01: Hydrology Data from Antarctic COOKIES Voyage

January 02 to February 25, 2026, the RV Investigator voyage IN2026_V01 collected hydrology samples from the Antarctic region. The dataset contains processed measurements of salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, and ammonium from Niskin bottles at various depths. It is archived by the CSIRO National Collections and Marine Infrastructure Information and Data Centre.

Use Cases

• Modeling ocean nutrient cycles based on phosphate, silicate, nitrate, and ammonium measurements.
• Analyzing water mass properties and mixing based on salinity and temperature profiles from CTD deployments.
• Studying marine ecosystem productivity based on dissolved oxygen and nutrient concentration data.

Strengths

• Data is quality-controlled and processed, as stated in the description.
• Voyage period is precisely defined from January 02, 2026 to February 25, 2026.
• Specific chemical parameters analyzed are listed: salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, and ammonium.

Limitations

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