Surface underway data from NOAA Ship Ronald H. Brown tracks chemical, meteorological, and physical conditions in the Atlantic Ocean. The collection includes measurements of air and water partial pressure of carbon dioxide (pCO2), sea surface temperature, salinity, and barometric pressure. Data were gathered by NOAA NCEI during cruises spanning from January 6 to December 20, 2020.
Use Cases
- Analyze the relationship between sea surface temperature and pCO2 in water to study seasonal carbon solubility changes.
- Model the air-sea difference of pCO2 using concurrent measurements of barometric pressure and salinity.
- Validate satellite-derived sea surface temperature products using in-situ measurements from the CO2 gas analyzer and equilibrator system.
- Investigate spatial and temporal trends in atmospheric pCO2 across Atlantic Ocean cruise transects.
Strengths
- Data collection spans nearly a full year, from 2020-01-06 to 2020-12-20, capturing seasonal variation.
- Includes multiple coordinated variables (pCO2, temperature, salinity, pressure) for integrated analysis.
- Part of the established Ship of Opportunity Program (SOOP), indicating standardized collection protocols.
Limitations
- Sample size and spatial resolution are unknown, limiting assessment of statistical power.
- Data is from a single vessel's track, not a spatially comprehensive grid of the Atlantic Ocean.
- The dataset is a snapshot from 2020 and may not reflect more recent ocean conditions.
