Hydrology data from the RV Investigator voyage IN2026_V02, which took place between March 17 and April 17, 2026. Samples for salinity, dissolved oxygen, and nutrients were collected from Niskin bottles at various depths during CTD deployments. The processed dataset is archived at the CSIRO National Collections and Marine Infrastructure Information and Data Centre in Hobart.
Use Cases
- Analyze vertical nutrient profiles based on phosphate, silicate, nitrate plus nitrite, and ammonium measurements.
- Study oceanographic conditions and water mass properties based on salinity and temperature data from CTD deployments.
- Model fine-scale ocean dynamics in the Ningaloo Coast region based on spatially and temporally resolved hydrology samples.
Strengths
- Data has been processed and quality-controlled, as stated in the description.
- Covers a specific one-month voyage period from March 17 to April 17, 2026.
- Includes multiple key water chemistry parameters: salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, and ammonium.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic and temporal bias inherent to the single voyage.
