Coral Sea Hydrology Data from RV Investigator Voyage IN2025_V06

Australia's Coral Sea Marine Park provides hydrology data from a 2025 research voyage. The dataset contains quality-controlled measurements of salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, and ammonium collected via CTD deployments. Samples were gathered between October 10 and November 14, 2025, on the RV Investigator voyage IN2025_V06.

Use Cases

• Analyze vertical profiles of salinity and dissolved oxygen from CTD deployments to study water column stratification.
• Model relationships between nutrient parameters like phosphate, silicate, and nitrate plus nitrite to assess marine biogeochemistry.
• Correlate ammonium concentrations with other water chemistry measurements to investigate nutrient cycling in the Coral Sea.

Strengths

• Data is quality-controlled and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.
• Covers a specific temporal range from October 10 to November 14, 2025.
• Includes six key water chemistry parameters: salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, and ammonium.

Limitations

• Sample size and spatial resolution are unknown, limiting statistical power for some analyses.
• Data format includes HTML and PNG, which may require extraction or conversion for quantitative tabular analysis.
• Geographic coverage is limited to the Coral Sea Marine Park, reducing generalizability to other ocean regions.
