CLIVAR A13.5 2010: Atlantic Ocean Carbon and Hydrographic Measurements

From March 8 to April 17, 2010, this dataset contains discrete sample and profile data collected aboard the NOAA Ship Ronald H. Brown in the North and South Atlantic Ocean. It includes measurements of carbon system parameters like dissolved inorganic carbon, alkalinity, and pCO2, alongside tracers such as CFCs, SF6, and stable isotopes. The data were collected as part of the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program to quantify changes in ocean heat, freshwater, and carbon storage.

Use Cases

• Quantifying changes in ocean carbon storage based on dissolved inorganic carbon and alkalinity measurements.
• Tracing water mass age and circulation using chlorofluorocarbon (CFC-11, CFC-12) and sulfur hexafluoride (SF6) concentrations.
• Studying ocean acidification trends by analyzing pH and partial pressure of carbon dioxide data.
• Investigating nutrient cycling and primary productivity through nitrate, phosphate, and silicate profiles.

Strengths

• Contains a wide suite of co-located chemical, physical, and carbon system parameters from a single cruise.
• Data collection follows a standardized repeat hydrography program (CLIVAR), enabling temporal comparison.
• Instruments used are explicitly listed and include high-precision tools like alkalinity titrators and coulometers.

Limitations

• Key metadata such as row count, column names, and license information are missing from all platform entries.
• The dataset's last update date conflicts between sources (2010-04-17 and 2026-03-06), creating uncertainty about versioning.
• The specific spatial resolution (station locations) and data processing level are not described.
