DY103 Cruise: Surface pCO2, Temperature, and Salinity in the North Atlantic

R/V Discovery collected these surface underway measurements during the Shelf Seas Biogeochemistry cruise DY103 in 2019. The dataset includes concurrent readings for the partial pressure of carbon dioxide in both water and atmosphere, alongside sea surface temperature, salinity, and barometric pressure. These measurements support the study of ocean carbon cycling and air-sea gas exchange in coastal and shelf seas.

Use Cases

• Calculating air-sea CO2 flux based on concurrent atmospheric and aquatic pCO2 measurements.
• Analyzing correlations between sea surface temperature and carbon dioxide partial pressure in water.
• Studying coastal carbon dynamics using data from the English Channel and Celtic Sea.
• Validating ocean carbon models with in-situ surface underway data from a research vessel.

Strengths

• Data collection occurred during a dedicated, named research cruise (DY103) aboard the R/V Discovery.
• Includes directly measured, concurrent parameters (pCO2 in air and water, SST, SSS, pressure) crucial for flux calculations.
• Dataset is hosted on multiple authoritative platforms (NASA Earthdata, Data.gov), indicating vetting and importance.

Limitations

• Column names and precise data structure are not provided in any source description.
• Key metadata like row count, file size, and license are consistently listed as unknown or 'None'.
• Sources conflict on the 'last updated' date (2019-07-09 vs. 2026-03-05), creating uncertainty about maintenance.
