Surface underway measurements of partial pressure of carbon dioxide, water temperature, salinity, wind speed, and direction collected during NOAA Ship Ronald H. Brown cruises from February 12 to December 22, 2004. The data were collected by Rik Wanninkhof of NOAA Atlantic Oceanographic and Meteorological Laboratory using carbon dioxide gas analyzers, equilibrators, and thermosalinographs. The dataset includes 11 cruise segments identified as RB200401 through RB200411.
Use Cases
- Modeling ocean-atmosphere carbon dioxide flux based on partial pressure measurements in water and air.
- Analyzing correlations between seawater carbon dioxide levels and water temperature or salinity.
- Studying wind patterns and their potential influence on surface gas exchange rates.
- Calibrating or validating autonomous carbon dioxide measurement instruments.
Strengths
- Data covers a specific temporal range from February 12 to December 22, 2004.
- Includes measurements from 11 distinct cruise segments.
- Specifies the instruments used: Carbon dioxide gas analyzer, shower head chamber equilibrator, and thermosalinographs.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the specific NOAA ship cruises.
