Marine National Facility Processed Underway Voyage Data at 5-Second Intervals

Marine National Facility (MNF) Processed Underway Parquet Data contains quality-controlled navigation, oceanographic, and atmospheric measurements from research voyages. The data, processed and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre, is supplied to the Australian Ocean Data Network and other global repositories. Data points are available at 5-second intervals.

Use Cases

• Validate satellite sea surface temperature measurements based on the quality-controlled underway SST data.
• Model ocean-atmosphere gas exchange based on pCO2 and atmospheric trace gas measurements.
• Analyze ship navigation and environmental conditions for voyage planning based on GPS, speed, heading, and meteorological data.
• Study phytoplankton dynamics based on fluorescence and photosynthetically active radiation (PAR) data.
• Calibrate meteorological instruments based on the dual wind speed and direction measurements from vane and ultrasonic sensors.

Strengths

• Data is quality-controlled and supplied to authoritative repositories like the IMOS AODN.
• Contains a wide range of synchronized measurements including navigation, ocean water properties, and atmospheric variables.
• High temporal resolution with data available at 5-second intervals.
• Processed and archived by a recognized national research institution (CSIRO NCMI IDC).

Limitations

• Not all variables are quality controlled; users must check for existing QC flags in the datasets.
• Row count and total data volume are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
