Marine National Facility Processed Underway Ocean and Atmospheric Data

Processed Underway data from Marine National Facility voyages includes navigation, thermosalinograph, and atmospheric measurements. The data are quality-controlled, archived by CSIRO NCMI IDC, and made available at 5-second intervals. These data are supplied to the IMOS AODN and other global repositories for uses like satellite sea surface temperature validation.

Use Cases

• Validate satellite sea surface temperature measurements based on quality-controlled thermosalinograph and radiometer data.
• Analyze oceanographic transects based on continuous navigation and water property data.
• Study marine-atmosphere gas exchange based on pCO2 and trace gas measurements.
• Model ocean currents and vessel performance based on GPS, gyro, and Doppler log data.

Strengths

• Data are quality-controlled and archived by a recognized institution (CSIRO NCMI IDC).
• Measurements are recorded at a high temporal resolution of 5-second intervals.
• Data cover three distinct domains: navigation, water column properties, and atmospheric conditions.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• Not all variables are quality controlled; users must check for existing QC flags.
