RV Investigator Underway Voyage Data: Navigation, Ocean, and Atmospheric Measurements

Continuous 5-second interval data from the RV Investigator's IN20YY_VNN voyage includes navigation, ocean salinity/temperature/fluorescence, and atmospheric wind/radiation/ozone measurements. Quality-controlled data is supplied to the IMOS AODN and the Australian Bureau of Meteorology for satellite sea surface temperature validation. The CSIRO National Collections and Marine Infrastructure Information and Data Centre processed and archived this data, available in NetCDF and ASCII formats.

Use Cases

• Validate satellite sea surface temperature (SST) data based on the thermosalinograph and radiometer measurements.
• Model ocean-atmosphere carbon exchange based on pCO2 and atmospheric trace gas readings.
• Analyze ship navigation and environmental conditions based on GPS, gyro, wind, and wave data.
• Study phytoplankton dynamics based on water fluorescence and photosynthetically active radiation (PAR) data.

Strengths

• Data is quality-controlled and supplied to global repositories like the IMOS AODN.
• Measurements are recorded at high temporal resolution, available at 5-second, 10-second, 1-minute, and 5-minute intervals.
• Includes a wide range of concurrent oceanographic, navigation, and atmospheric variables from calibrated instruments.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• 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.
