Polar Ocean Carbon and Hydrography Data from CLIVAR Cruise ANT_XXVII_2, 2010-2011

Discrete sample and profile data collected from the RV POLARSTERN in the South Atlantic, South Pacific, and Southern Oceans from 2010-11-28 to 2011-02 05. The data include dissolved inorganic carbon, total alkalinity, stable isotopes, nutrients, and physical properties like temperature and salinity. These data were collected by Mario Hoppema of the Alfred Wegener Institute as part of the CLIVAR_A12_ANT_XXVII_2 cruise to quantify changes in ocean carbon storage and transport.

Use Cases

• Modeling ocean acidification and carbon storage based on dissolved inorganic carbon and total alkalinity measurements.
• Studying nutrient cycling and biological productivity in polar oceans based on nitrate, phosphate, and silicate data.
• Analyzing water mass properties and circulation based on temperature, salinity, and dissolved oxygen profiles.
• Investigating carbon isotope tracers for ocean ventilation and carbon cycle processes based on delta carbon-13 and delta carbon-14 data.

Strengths

• Data covers a specific research cruise (ANT_XXVII_2) with a defined temporal range from 2010-11-28 to 2011-02-05.
• Includes multiple key ocean carbon and hydrographic parameters such as DIC, alkalinity, nutrients, and isotopes.
• Collected by a recognized research institution (Alfred Wegener Institute) as part of the international CLIVAR program.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Description metadata is limited; actual data quality requires manual inspection after download.
