Underway data from the 2014 Linnaeus research voyage LI2014_V04, which deployed and recovered moorings and CTDs. The dataset includes GPS navigation, thermosalinograph, and fluorometer measurements recorded at 1-second intervals. It was collected by the Australian Ocean Data Network on March 19, 2014, during a voyage from Hillarys, Western Australia, to the Perth Canyon and back.
Use Cases
- Track ship movement and calculate ocean currents based on GPS latitude, longitude, direction, and speed data.
- Analyze seawater temperature and salinity profiles based on thermosalinograph (TSG) data.
- Study phytoplankton distribution and biomass based on fluorometer measurements.
- Correlate physical and biological oceanographic variables along the ship's track.
Strengths
- Data is stored at high-resolution 1-second intervals, allowing for detailed temporal analysis.
- Includes multiple data streams (navigation, thermosalinograph, fluorometer) for integrated analysis.
- A specific data processing report for the voyage is referenced, suggesting documented quality control.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the single-day voyage in Western Australian waters.
