From November 2007 to February 2008, the research vessel Polarstern collected discrete sample and profile data in the South Atlantic and Southern Oceans (>60°S). The dataset includes dissolved inorganic carbon, total alkalinity, dissolved oxygen, nitrate, salinity, and temperature measurements using CTD and bottle instruments. It was collected by researchers from the Alfred Wegener Institute as part of the CLIVAR_A12_ANT-XXIV_2 cruise.
Use Cases
- Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and total alkalinity measurements.
- Analyzing water column properties and ocean circulation based on CTD-derived salinity, temperature, and hydrostatic pressure profiles.
- Studying nutrient dynamics in polar oceans based on nitrate concentration data.
- Investigating ocean acidification trends in the Southern Ocean based on carbonate system parameters.
Strengths
- Data collected during a dedicated research cruise (ANT-XXIV_2) over a focused period from 2007-11-28 to 2008-02-04.
- Includes key carbonate system variables (DIC, TA) alongside physical oceanographic parameters (temperature, salinity, oxygen).
- 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 is unknown, which may limit suitability assessment.
