EB04 Cruise: Ocean Carbon and Sea Surface Measurements

Underway measurements from the R/V Roger Revelle during December 2004 capture the air-sea exchange of carbon dioxide across the North and South Pacific. Data include the partial pressure (fugacity) of CO2 in both air and water, salinity, and sea surface temperature. This collection supports the study of ocean acidification and carbon flux dynamics.

Use Cases

• Calculating air-sea CO2 flux based on the difference in partial pressure between water and atmosphere.
• Analyzing correlations between sea surface temperature and carbon dioxide fugacity.
• Validating ocean carbon cycle models with in-situ surface underway observations.
• Assessing spatial variability of surface ocean carbon parameters across the Pacific basin.

Strengths

• Data collection uses specific, high-quality instruments including a CO2 gas analyzer and thermosalinographs.
• Provides a continuous, three-week time series from a defined research cruise (EB04).
• Cross-platform presence on NASA Earthdata and Data.gov signals its importance and curation.

Limitations

• Column names and exact row count are not provided in any source, limiting immediate usability.
• Metadata conflicts exist: one source lists a last update date of 2004-12-27, while others list 2026-03-05.
• License information is not specified.
