CARINA: Discrete Ocean Chemistry Profiles from the South Atlantic

CARINA/29HE19960117 provides 15 biogeochemical variables, including alkalinity, nutrients, and chlorophyll, collected via CTD and bottle sampling from the HESPERIDES research vessel in the South Atlantic Ocean. This cruise data is part of the CARINA synthesis project, which created an internally consistent dataset for carbon system studies across the Atlantic, Arctic, and Southern Oceans. The dataset includes measurements from January 17 to February 5, 1996.

Use Cases

• Analyzing carbon system dynamics based on alkalinity and pH measurements.
• Studying nutrient cycling and phytoplankton biomass using nitrate, phosphate, silicate, and chlorophyll a data.
• Investigating water column structure and properties using CTD-derived salinity, temperature, and hydrostatic pressure profiles.
• Calculating particulate organic matter fluxes from particulate organic carbon and nitrogen measurements.
• Assessing dissolved oxygen levels and ammonium concentrations for biological activity studies.

Strengths

• Includes 15 specific biogeochemical variables, enabling multi-parameter analysis.
• Data is part of the CARINA international synthesis project, suggesting quality control and internal consistency.
• Collection methods are specified (CTD and bottle), indicating standardized oceanographic practices.

Limitations

• Key metadata such as row count, column names, and license are unknown across all platforms.
• The last updated date conflicts: one source shows 2026-03-05, another shows 1996-02-05.
• Author affiliations are inconsistently reported between sources.
