Hydrology data from the RV Investigator voyage IN2025_E01 collected between February 19 and March 01, 2025. Samples were taken from Niskin bottles at various depths during CTD deployments and analyzed for salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, and ammonium. The processed dataset is archived at the CSIRO National Collections and Marine Infrastructure Information and Data Centre.
Use Cases
- Analyze vertical profiles of salinity and dissolved oxygen based on CTD deployments
- Study nutrient concentrations (phosphate, silicate, nitrate, ammonium) in the water column
- Assess water quality and biogeochemical cycles based on the suite of analyzed parameters
Strengths
- Data is quality-controlled and processed according to the description
- Parameters include a defined suite of six key oceanographic measurements
- Voyage took place over a specific 12-day period in February-March 2025
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
