RV Investigator IN2025_E01: Hydrology Data from Sea Trials

RV Investigator voyage IN2025_E01 collected hydrology data during sea trials and calibrations between February 19 and March 01, 2025. The Marine National Facility processed and archived the data, which includes parameters like salinity, dissolved oxygen, and nutrients from Niskin bottle samples at various depths. This quality-controlled dataset is held by the CSIRO National Collections and Marine Infrastructure Information and Data Centre in Hobart.

Use Cases

• Modeling ocean water mass properties based on salinity and temperature data.
• Analyzing nutrient distributions (phosphate, silicate, nitrate) for biogeochemical studies.
• Calibrating Conductivity-Temperature-Depth (CTD) sensors using quality-controlled in-situ samples.
• Studying dissolved oxygen levels in the water column from sampled depths.

Strengths

• Data has been processed and quality-controlled, as stated in the description.
• Specific voyage dates (February 19 to March 01, 2025) and departure/return port (Hobart) are provided.
• A clear list of analyzed parameters (salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, ammonium) is documented.

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 bias inherent to the specific voyage track from Hobart.
