IN2025_E01: Hydrology Data from RV Investigator Sea Trials

Marine hydrology data from the RV Investigator voyage IN2025_E01, which took place between February 19 and March 01, 2025, departing from and returning to Hobart. The dataset contains processed measurements of salinity, dissolved oxygen, and nutrients collected from Niskin bottles at various depths during CTD deployments. It is archived by the CSIRO National Collections and Marine Infrastructure Information and Data Centre.

Use Cases

• Modeling oceanographic conditions based on salinity and temperature profiles.
• Analyzing nutrient distributions (phosphate, silicate, nitrate) for biogeochemical studies.
• Assessing water mass characteristics and dissolved oxygen levels.
• Calibrating or validating satellite-derived ocean data products.

Strengths

• Data is described as processed and quality-controlled.
• Voyage period is precisely defined as February 19 to March 01, 2025.
• Specific measured parameters (salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, ammonium) are listed.
• Associated voyage and data processing reports provide additional context.

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 a single, short voyage.
