November 15 to December 20, 2023, the RV Investigator voyage IN2023_V07 collected multidisciplinary ocean data using a towed TRIAXUS platform south of Tasmania. The Australian Ocean Data Network published this dataset, which includes CTD, dissolved oxygen, nitrate, fluorescence, and plankton counter measurements. The primary focus was to validate SWOT satellite observations and study small-scale motions in the Antarctic Circumpolar Current.
Use Cases
- Validate SWOT satellite sea surface height observations based on in-situ subsurface CTD and dissolved oxygen measurements.
- Characterize small-scale variability in ocean circulation based on data collected across a standing meander of the Antarctic Circumpolar Current.
- Quantify cross-front transport of heat and carbon based on multidisciplinary measurements of physical and biogeochemical parameters.
- Investigate interconnected physical and biological processes at small scales based on chlorophyll fluorescence and plankton counter data.
Strengths
- Data collected from duplicate sensors on a Seabird SBE9plus CTD, suggesting redundancy.
- 5 Triaxus tows were conducted with a total towing time of 121.75 hours.
- Multidisciplinary measurements include CTD, dissolved oxygen, nitrate, fluorescence, transmissometer, PAR, and plankton counts.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The description notes software crashes and schedule failures during some tows, indicating potential data gaps.
