Coral Sea Marine Park Hydrology Profiles from RV Investigator Voyage

October 10 to November 14, 2025 data collection from the RV Investigator voyage IN2025_V06 in the Coral Sea Marine Park. The dataset contains processed hydrology measurements including salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, and ammonium, sampled from Niskin bottles at various depths during CTD deployments. It was quality-controlled and archived by the CSIRO National Collections and Marine Infrastructure Information and Data Centre.

Use Cases

• Analyzing correlations between salinity, dissolved oxygen, and nutrient concentrations like phosphate and silicate across sampled depths.
• Modeling vertical profiles of nitrate plus nitrite and ammonium to understand nutrient availability for phytoplankton.
• Comparing water column chemistry from different CTD deployment locations within the Coral Sea Marine Park.
• Investigating relationships between temperature (from CTD) and dissolved oxygen levels for ocean health assessments.

Strengths

• Quality-controlled processing documented in a Data Processing Report.
• Specific temporal coverage from October 10 to November 14, 2025.

Limitations

• Unknown row count and sample size limits statistical power.
• Geographic scope is restricted to the Coral Sea Marine Park voyage track.
• Data is static from a single 2025 voyage, not a continuous time series.
