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

A voyage between unspecified dates collected continuous underway data from the RV Investigator. The dataset includes navigation, thermosalinograph, and atmospheric measurements, processed and quality-controlled by CSIRO NCMI IDC. Data are available in 5-second to 5-minute intervals in NetCDF and ASCII formats.

Use Cases

• Validate satellite sea surface temperature (SST) data based on the quality-controlled SST and radiometer measurements.
• Model ocean-atmosphere interactions based on concurrent water salinity, temperature, pCO2, and atmospheric wind/humidity data.
• Analyze vessel track and environmental conditions for voyage planning based on navigation (GPS, heading) and meteorological data.
• Study phytoplankton dynamics based on water fluorescence and photosynthetically active radiation (PAR) measurements.

Strengths

• Data are quality-controlled and supplied to global repositories like IMOS AODN.
• Multiple temporal resolutions are available, including 5-second, 10-second, 1-minute, and 5-minute intervals.
• Includes measurements from three integrated systems: navigation, thermosalinograph, and atmospheric sensors.

Limitations

• The specific voyage time range, departure, and arrival locations are not provided in the available metadata.
• 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.
