Marine National Facility Processed Underway Data at 5-Second Intervals

Processed Underway data from Marine National Facility voyages includes navigation, thermosalinograph, and atmospheric measurements recorded every 5 seconds. The data are quality-controlled by CSIRO National Collections and Marine Infrastructure and supplied to the IMOS AODN and other global repositories. It supports satellite sea surface temperature validation by the Australian Bureau of Meteorology.

Use Cases

• Validate satellite sea surface temperature measurements based on quality-controlled thermosalinograph data.
• Analyze ocean-atmosphere gas exchange based on pCO2 and trace gas measurements.
• Model ship navigation and track patterns based on GPS, speed, and heading data.
• Study phytoplankton dynamics based on fluorescence and photosynthetically active radiation data.
• Correlate meteorological conditions with oceanographic parameters based on combined atmospheric and water column measurements.

Strengths

• Data are recorded at a high temporal resolution of 5-second intervals.
• Includes a wide range of variables across navigation, water column, and atmospheric domains.
• Undergoes quality control processing by CSIRO and is archived for long-term access.

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.
