2006-11-07 to 2015-10-04 of surface underway chemical, meteorological, and physical data collected during R/V Arni Fridriksson cruises in the Irminger Sea and North Atlantic. The dataset includes measurements of sea surface temperature, equilibrator temperature and pressure, and mole fraction and partial pressure of carbon dioxide. Data were collected by NOAA NCEI using carbon dioxide gas analyzers and equilibrator chambers.
Use Cases
- Calculate air-sea CO2 flux using pCO2 at TEQ (PCO2TEQ) and sea surface temperature (SST) measurements.
- Analyze seasonal and interannual variability of surface ocean carbon (xCO2, PCO2TEQ) in the North Atlantic from 2006 to 2015.
- Calibrate satellite-derived SST products with in-situ sea surface temperature (SST) records from ship transects.
- Model the relationship between equilibrator conditions (TEQ, PEQ) and derived pCO2 values (PCO2TEQ).
Strengths
- Nine-year temporal coverage from 2006 to 2015.
- Includes multiple directly measured variables: SST, TEQ, PEQ, xCO2, and PCO2TEQ.
- Data collected via established instruments: CO2 gas analyzer and shower head chamber equilibrator.
Limitations
- Unknown total number of observations or spatial resolution.
- Limited to specific ship cruise tracks in the Irminger Sea and North Atlantic, not a continuous global record.
- Data collection ended in 2015, limiting analysis of recent trends.
