RV Investigator IN2026_V01 Hydrology Data from Antarctic Voyage

Hydrology data from the RV Investigator voyage IN2026_V01, which took place between January 02, 2026 and February 25, 2026. The dataset contains processed measurements of salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, and ammonium from water samples collected during CTD deployments. 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 stratification based on salinity and temperature profiles from CTD deployments.
• Studying dissolved oxygen dynamics in Antarctic waters based on the oxygen parameter.
• Calibrating satellite-derived oceanographic data using in-situ salinity and temperature measurements.

Strengths

• Data is described as processed and quality-controlled.
• Voyage spanned a specific 55-day period from January 02 to February 25, 2026.
• Associated voyage and data processing reports provide additional context.

Limitations

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