Oceanographic data from 5 Triaxus tows conducted during the RV Investigator voyage IN2023_V07 between November 15 and December 20, 2023. The voyage focused on the Antarctic Circumpolar Current south of Tasmania to validate SWOT satellite data. Data includes CTD, dissolved oxygen, transmissometer, PAR, ECO Triplet, nitrate, fluorescence, and LOPC measurements.
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 collected across an ACC meander.
- Quantify cross-frontal transport of heat and carbon based on multidisciplinary physical and biogeochemical sensor data.
- Investigate linkages between physical, biogeochemical, and biological processes at small spatial scales based on the suite of sensors deployed.
Strengths
- Data collected over a total towing time of 121.75 hours across 5 distinct tows.
- Includes a multidisciplinary suite of sensors (CTD, dissolved oxygen, transmissometer, PAR, ECO Triplet, nitrate, fluorescence, LOPC).
- Voyage had a specific scientific objective focused on a region of intense eddy activity for satellite validation.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
