Linnaeus Voyage LI2014_V04: Underway Oceanographic Data from Perth Canyon

Australian Ocean Data Network provides underway data from the Linnaeus research voyage LI2014_V04 on March 19, 2014. The dataset includes continuous GPS navigation, thermosalinograph, and fluorometer measurements recorded at 1-second intervals. Data is stored in NetCDF and CSV formats at 10-second and 5-minute aggregations.

Use Cases

• Track vessel trajectory and speed based on continuous GPS navigation data.
• Analyze seawater temperature and salinity profiles based on thermosalinograph measurements.
• Study phytoplankton distribution based on fluorometer data.
• Model oceanographic conditions in the Perth Canyon region based on the spatial coverage described.

Strengths

• Data is recorded at high temporal resolution, with 1-second intervals for the primary NetCDF files.
• Includes multiple sensor streams (navigation, thermosalinograph, fluorometer) for concurrent analysis.
• Data is available in both NetCDF and aggregated CSV (10-second, 5-minute) formats for different use cases.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data reflects a single-day temporal bias from the voyage on March 19, 2014.
