RV Investigator IN2025_V06: Hydrology Data from the Coral Sea Marine Park

Hydrology data from the RV Investigator voyage IN2025_V06, which took place between October 10, 2025 and November 14, 2025. The dataset contains processed measurements of salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, and ammonium from Niskin bottle samples at various depths. It is archived by the CSIRO National Collections and Marine Infrastructure Information and Data Centre.

Use Cases

• Modeling ocean biogeochemistry based on nutrient concentrations (phosphate, silicate, nitrate, ammonium).
• Assessing water mass properties and ocean circulation based on salinity and temperature profiles.
• Studying deep-sea ecosystem health based on dissolved oxygen levels.
• Analyzing spatial and vertical gradients in water quality parameters across the Coral Sea Marine Park.

Strengths

• Data has been processed and quality-controlled, as stated in the description.
• Covers six key oceanographic parameters: salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, and ammonium.
• 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 for large-scale modeling.
