RV Investigator IN2025_V01: Underway Ocean and Atmospheric Data

Underway data from the RV Investigator voyage IN2025_V01 was collected between March 08 and March 17, 2025, departing from and returning to Hobart. The Marine National Facility processed and archived this data, which includes navigation, thermosalinograph, and atmospheric measurements. Data are available at intervals from 5 seconds to 5 minutes in NetCDF and ASCII formats.

Use Cases

• Validate satellite sea surface temperature (SST) measurements based on the radiometer/SST data mentioned.
• Study ocean-atmosphere carbon flux using the underway pCO2 and atmospheric trace gas measurements.
• Analyze marine primary productivity patterns based on fluorescence and Photosynthetically Active Radiation (PAR) data.
• Model ship navigation and ocean currents using the high-frequency GPS, gyro, and Doppler Log data.

Strengths

• Data is quality-controlled and supplied to the IMOS AODN and other global repositories.
• Available at high temporal resolutions, including 5-second intervals.
• Covers a comprehensive suite of oceanographic and atmospheric variables as listed in the description.

Limitations

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