RV Investigator Voyage IN2025_V01: Underway Ocean and Atmospheric Data

March 08 to March 17, 2025 data collected from the Marine National Facility RV Investigator voyage IN2025_V01. The dataset contains quality-controlled, continuously recorded underway measurements including navigation, thermosalinograph, and atmospheric data. It is processed and archived by CSIRO National Collections and Marine Infrastructure and made available via the Australian Ocean Data Network.

Use Cases

• Validate satellite sea surface temperature measurements based on the quality-controlled SST data supplied to the Australian Bureau of Meteorology.
• Analyze oceanographic conditions and water properties based on thermosalinograph data including salinity, temperature, fluorescence, pCO2, and oxygen.
• Study marine meteorological patterns based on atmospheric data including wind, humidity, solar radiation, air temperature, pressure, rain, ozone, and trace gases.
• Track vessel navigation and ocean surface conditions for voyage reconstruction based on GPS, speed, heading, and course over ground data.

Strengths

• Data is quality-controlled and supplied to the IMOS AODN and other global repositories.
• Available at multiple time intervals: 5 sec (NetCDF), 5 sec, 10 sec, 1 min, and 5 min (ASCII).
• Covers a specific voyage period from March 08, 2025 to March 17, 2025.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Not all variables are quality controlled; users must check for existing QC flags in the datasets.
• Row count is unknown, which may limit suitability assessment.
