Benguela Stream Surface Underway Carbon and Oceanographic Data

Nine research cruises aboard the Benguela Stream collected surface underway data from the Caribbean Sea, English Channel, and North Atlantic Ocean between April 30 and December 19, 2014. The dataset includes measurements of the partial pressure of carbon dioxide in both the atmosphere and seawater, alongside salinity, sea surface temperature, dissolved oxygen, nutrients, and wind conditions. These observations were made using a carbon dioxide gas analyzer and a barometric pressure sensor.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure measurements in air and water.
• Analyzing correlations between sea surface temperature, salinity, and dissolved inorganic carbon.
• Modeling ocean acidification trends using carbonate system parameters.
• Studying nutrient dynamics (nitrate, phosphate, silicate) in surface waters across ocean basins.

Strengths

• Data originates from nine distinct research cruises, providing multiple sampling events.
• Includes directly measured, co-located atmospheric and seawater CO2 partial pressures for flux calculation.
• Covers a wide geographic area spanning the Caribbean Sea, English Channel, and North Atlantic Ocean.

Limitations

• Key metadata such as row count, file size, and specific column names are unavailable across all sources.
• Conflicting last updated dates (2014-12-19 vs. 2026-03-05) create uncertainty about data currency.
• The license and detailed authorship information are not provided.
