RV Investigator Voyage IN2025_V01: Marine and Atmospheric Underway Data

Australian marine data collected by the RV Investigator voyage IN2025_V01 between March 08 and March 17, 2025, from Hobart and returning to Hobart. The dataset contains quality-controlled underway measurements of navigation, water properties, and atmospheric conditions, processed by CSIRO National Collections and Marine Infrastructure. Data are available in NetCDF and ASCII formats at intervals from 5 seconds to 5 minutes.

Use Cases

• Validate satellite sea surface temperature (SST) products based on in-situ radiometer/SST data.
• Model ocean-atmosphere interactions based on concurrent water salinity, pCO2, and atmospheric measurements.
• Analyze ship navigation patterns and environmental conditions based on GPS, speed, heading, and meteorological data.
• Study marine biogeochemistry based on water fluorescence, oxygen, and photosynthetically active radiation (PAR) data.

Strengths

• Data are quality-controlled and supplied to global repositories like the IMOS AODN.
• Multiple temporal resolutions are available, including 5-second, 10-second, 1-minute, and 5-minute intervals.
• Voyage took place over a defined period from March 08 to March 17, 2025.

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.
