121.75 hours of towed Triaxus data collected to validate the SWOT satellite mission. The Australian Ocean Data Network gathered multidisciplinary ocean measurements south of Tasmania between November 15 and December 20, 2023. Five tows captured CTD, dissolved oxygen, nitrate, and plankton data across a standing meander of the Antarctic Circumpolar Current.
Use Cases
- Validate SWOT satellite sea surface height observations based on in-situ subsurface ocean measurements.
- Characterize small-scale variability in ocean circulation based on data from a region of intense eddy activity.
- Quantify cross-front transport of heat and carbon based on multidisciplinary physical and biogeochemical sensor data.
- Investigate interconnected physical and biological processes based on simultaneous CTD, nitrate, and plankton counter readings.
Strengths
- Data collection spanned 121.75 hours across 5 distinct tows.
- Duplicate sensors were used for core CTD and dissolved oxygen measurements.
- Multidisciplinary data includes physical, biogeochemical, and biological parameters from multiple sensors.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
