CLIVAR A16N 2003: North and South Atlantic Ocean Carbon and Hydrographic Measurements

From June to August 2003, discrete sample and profile data were collected from the NOAA Ship RONALD H. BROWN in the North and South Atlantic Ocean. The dataset includes measurements for carbon dioxide partial pressure, dissolved inorganic carbon, alkalinity, salinity, temperature, nutrients, and chlorofluorocarbons. It was collected by researchers from NOAA AOML, PMEL, and RSMAS as part of the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and pH measurements.
• Analyzing water mass age and circulation using chlorofluorocarbon (CFC-11, CFC-12, CFC-113) tracer data.
• Studying nutrient cycles and primary production based on nitrate, nitrite, phosphate, and silicate concentrations.
• Calibrating and validating satellite-derived sea surface salinity and temperature products using in-situ CTD data.

Strengths

• Data covers a specific cruise (CLIVAR_A16N_2003) from June to August 2003, providing a temporal snapshot.
• Includes a multi-parameter suite of over 20 variables relevant to ocean carbon and hydrography.
• Collected by authoritative institutions (NOAA AOML, PMEL, RSMAS) as part of an international 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 for large-scale modeling.
• Data may reflect geographic and temporal bias inherent to a single ship cruise in 2003.
