Discovery 233 research cruise data contains measurements of atmospheric and oceanic halocarbons and oceanic carbon dioxide. The dataset includes 101 measurements of oceanic CFC-11, CFC-12, CFC-113, and carbon tetrachloride, plus 62 measurements of oceanic pCO2 and atmospheric halocarbons for 27 species. Researchers Claudia Dimmer, Cristina Peckett, Iris Soler-Aristegui, Denise Smythe-Wright, Luis Laglera, and Maria Somoza-Rodriguez collected the data during the World Ocean Circulation Experiment cruise from April 23 to June 1, 1998.
Use Cases
- Analyze spatial trends of oceanic CFC-11, CFC-12, CFC-113, and carbon tetrachloride concentrations across the North Atlantic transect.
- Correlate oceanic pCO2 measurements with atmospheric halocarbon species data to study air-sea gas exchange.
- Use the 27 atmospheric halocarbon species measurements to model historical halogen loading and ozone depletion potential.
- Investigate temporal changes in trace gas concentrations during the April-June 1998 cruise period using the time-series data.
Strengths
- Provides 101 discrete measurements for key oceanic halocarbons (CFC-11, CFC-12, CFC-113, carbon tetrachloride).
- Includes 62 concurrent measurements of oceanic partial pressure of CO2 (pCO2).
- Covers a specific spatial transect in the North Atlantic from +64N to +20N latitude and -10W to -25W longitude.
- Captures data for 27 distinct atmospheric halocarbon species, offering a detailed chemical profile.
Limitations
- Limited temporal scope, with all data collected during a single 40-day cruise in 1998.
- Sample size is modest, with 101 and 62 measurements for the primary oceanic variables.
- Data is over 25 years old, which may limit relevance for studying current ocean-atmosphere dynamics.
