GO-SHIP A22: North Atlantic Ocean Hydrographic and Carbon Chemistry Profiles from 2021

Discrete profile measurements of dissolved inorganic carbon, alkalinity, chlorofluorocarbons, and other hydrographic variables collected during the R/V Thomas G. Thompson cruise on GO-SHIP repeat section A22 in the North Atlantic Ocean from 2021-04-20 to 2021-05 16. The dataset was collected by the US GO-SHIP program, a major contributor to the international GO-SHIP effort for quasi-decadal, full water column observations. These measurements are part of a program to monitor long-term changes in heat, freshwater, carbon, oxygen, and other tracers in the global ocean.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and pH measurements.
• Analyzing decadal variability in ocean heat and freshwater storage based on temperature and salinity profiles.
• Tracking anthropogenic tracer dispersion based on chlorofluorocarbon (CFC11, CFC12) data.
• Studying ocean biogeochemistry and nutrient cycles based on dissolved oxygen and nutrient variables.

Strengths

• Data collected as part of the standardized, high-accuracy international GO-SHIP program.
• Provides full water column observations from surface to bottom.
• Covers a specific repeat transoceanic section (A22) at approximately 52°20'N in the North Atlantic.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single cruise in 2021; temporal coverage is limited without access to other repeat surveys.
