North Atlantic and Pacific Ocean surface data includes partial pressure of carbon dioxide, salinity, sea surface temperature, air temperature, barometric pressure, and wind measurements. The dataset was collected by Rik Wanninkhof of NOAA's Atlantic Oceanographic and Meteorological Laboratory during six research cruises from January 2008 to January 2009. Measurements were taken using underway instruments including carbon dioxide gas analyzers, thermosalinographs, and barometric pressure sensors.
Use Cases
- Calculate air-sea CO2 flux using the partial pressure difference (pCO2_air - pCO2_sea) and wind speed measurements.
- Analyze correlations between sea surface temperature, salinity, and the partial pressure of carbon dioxide to identify physical drivers of CO2 variability.
- Model oceanic carbon uptake in the North and South Atlantic/Pacific basins using time-series pCO2 data from the 2008 cruises.
- Calibrate satellite-derived sea surface temperature or salinity products using in-situ thermosalinograph measurements.
- Study regional marine meteorology by examining the relationship between barometric pressure, wind direction, and air temperature across ocean transects.
Strengths
- Data spans a full year from 2008-01-22 to 2009-01-11, capturing seasonal variability.
- Coverage includes multiple major ocean basins: North Atlantic, South Atlantic, North Pacific, South Pacific, and Rio de la Plata.
- Includes 10+ measured variables such as pCO2, salinity, SST, fluorescence, and wind parameters for a multi-parameter analysis.
Limitations
- The dataset's temporal coverage is limited to a single year (2008), preventing long-term trend analysis.
- Spatial coverage is restricted to the specific ship tracks of the Ronald Brown, leaving large geographic gaps.
- Sample data and column definitions are unavailable, complicating initial data exploration and validation.
