From February 10 to April 16, 2008, discrete sample and profile data were collected from the POLARSTERN research vessel in the South Atlantic and Southern Oceans (> 60 degrees South). The data include dissolved inorganic carbon, alkalinity, temperature, salinity, nutrients, dissolved oxygen, chlorofluorocarbons, and helium isotopes. It was collected by researchers from Alfred-Wegener-Institut, Groningen University, and the Royal Netherlands Institute for Sea Research as part of the CLIVAR_A12_ANTXXIV_3 cruise.
Use Cases
- Analyze ocean carbon storage and acidification based on dissolved inorganic carbon and total alkalinity measurements.
- Study water mass circulation and ventilation based on chlorofluorocarbon (CFC-11, CFC-12) and helium isotope tracers.
- Model nutrient dynamics in polar oceans based on nitrate, nitrite, phosphate, and silicate data.
- Calibrate and validate oceanographic models based on concurrent CTD profile data for temperature, salinity, and hydrostatic pressure.
Strengths
- Data covers a specific, high-latitude research cruise (ANT-XXIV/3) in the Southern Oceans.
- Includes a multi-parameter suite of chemical, physical, and tracer measurements relevant for carbon and hydrography studies.
- Associated with the international CLIVAR Global Ocean Carbon and Repeat Hydrography Program.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and dataset size are unknown, which may limit suitability assessment.
- Data may reflect geographic and temporal bias inherent to a single, two-month cruise.
