Description
Hydrology data from the RV Investigator voyage IN2025_E01 was collected between February 19 and March 01, 2025, during sea trials and calibrations departing from and returning to Hobart. Samples were drawn from Niskin bottles at various depths during CTD deployments, with analyzed parameters including salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, and ammonium. The dataset has been processed and quality-controlled by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.
Use Cases
Calibrating oceanographic sensors and models based on in-situ measurements of salinity and dissolved oxygen.
Analyzing nutrient distributions (phosphate, silicate, nitrate) to study marine biogeochemical cycles.
Assessing water quality and oceanographic conditions during a specific research voyage's sea trials.
Validating satellite-derived ocean data products using direct CTD cast sample measurements.
Strengths
Data has undergone quality-controlled processing, as stated in the source descriptions.
