CLIVAR A16N 2013: Atlantic Ocean Carbon and Hydrographic Profile Data

Discrete profile measurements of 15+ oceanographic variables, including dissolved inorganic carbon, chlorofluorocarbons, and stable isotopes, were collected during a 2013 NOAA research cruise. The data supports the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program's mission to quantify changes in ocean heat, freshwater, and CO2 storage. Measurements were taken from the NOAA Ship Ronald H. Brown in the Atlantic Ocean between August and October 2013.

Use Cases

• Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and pCO2 measurements.
• Tracing water mass age and circulation using chlorofluorocarbon (CFC-11, CFC-12) and sulfur hexafluoride (SF6) tracer data.
• Studying ocean acidification dynamics based on pH on seawater scale and total alkalinity.
• Analyzing biogeochemical cycles using dissolved organic carbon (DOC) and nutrient measurements.
• Investigating isotopic carbon cycling using delta C13 and delta C14 data.

Strengths

• Includes measurements for over 15 distinct hydrographic and chemical variables per profile.
• Data is tied to a specific, documented research cruise (NOAA Ship Ronald H. Brown, EXPOCODE 33RO20130803) with a clear temporal range (2013-08-03 to 2013-10-01).
• Part of a systematic global re-occupation program (CLIVAR) designed for change detection.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the single Atlantic Ocean transect.
