NOAA's dataset includes surface underway measurements of partial pressure of carbon dioxide (pCO2) in water and atmosphere, sea surface temperature, sea surface salinity, and barometric pressure. Data were collected during the R/V Kronprins Haakon cruise in the Atlantic Ocean from 2019-04-18 to 2019-05-22 using a General Oceanics pCO2 system. Calculations followed the methodology described by Pierrot (2009).
Use Cases
- Analyze ocean carbon uptake based on partial pressure of carbon dioxide (pCO2) measurements.
- Study sea surface temperature (SST) and salinity variations in the Atlantic Ocean.
- Model atmospheric-ocean CO2 exchange based on simultaneous water and atmosphere pCO2 data.
- Validate climate models using underway measurements of barometric pressure and sea surface conditions.
Strengths
- Data collected during a dedicated 35-day research cruise (2019-04-18 to 2019-05-22).
- Uses a specific, documented instrument (General Oceanics pCO2 system model 8050) and follows Pierrot (2009) methodology.
- Includes simultaneous measurements of pCO2 in both water and atmosphere, sea surface temperature, salinity, and barometric pressure.
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/temporal bias inherent to a single cruise track.
