Coral Sea Hydrology Data from RV Investigator Voyage IN2025_V06

Aggregating hydrology data from the RV Investigator voyage IN2025_V06, which took place from October 10 to November 14, 2025. It includes analyzed parameters such as salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, and ammonium from water samples collected at various depths during CTD deployments.

Use Cases

• Analyze vertical profiles of salinity and dissolved oxygen to study water column stratification in the Coral Sea.
• Investigate nutrient correlations between phosphate, silicate, and nitrate plus nitrite to assess marine productivity.
• Model ammonium concentrations relative to other nutrient parameters to examine nitrogen cycling dynamics.
• Map the spatial distribution of water chemistry parameters like silicate and phosphate across the Coral Sea Marine Park.

Strengths

• Data is quality-controlled and processed, as stated in the description.
• Covers a specific 36-day voyage period from October 10 to November 14, 2025.
• Includes multiple key water chemistry parameters: salinity, dissolved oxygen, and four nutrient types.
• Archived at the authoritative CSIRO National Collections and Marine Infrastructure Information and Data Centre.

Limitations

• The number of data rows, columns, and total sample size is unknown.
• Geographic coverage is limited to the specific track of the RV Investigator voyage in the Coral Sea.
• Data format includes HTML and PNG, which may not be immediately usable for quantitative analysis without extraction.
