NCEI Accession 0160489 contains surface underway measurements of carbon dioxide partial pressure in air and water, barometric pressure, wind speed, and wind direction. Data were collected by researchers from the Alfred Wegener Institute and Groningen University aboard the RV Polarstern across the Atlantic Ocean, Mediterranean Sea, and other regions from March 2014 to January 2015. The dataset includes observations from six distinct cruise legs.
Use Cases
- Calculate air-sea CO2 flux using partial pressure of carbon dioxide in water and atmosphere, wind speed, and barometric pressure.
- Analyze spatial patterns of surface ocean pCO2 across the Atlantic and Mediterranean basins from the cruise track data.
- Correlate atmospheric carbon dioxide measurements with concurrent meteorological variables like wind direction and speed.
- Validate satellite-derived ocean carbon products with in-situ pCO2 measurements from specific sea regions.
- Study seasonal carbon cycle variability in 2014 using time-series data from repeated cruise transects.
Strengths
- Data covers a wide geographic area including the North Atlantic Ocean, Mediterranean Sea, and Indian Ocean.
- Includes concurrent chemical and meteorological measurements for integrated analysis.
- Time range spans nearly 11 months from March 2014 to January 2015.
Limitations
- Specific row count, column details, and sample size are unknown.
- Data is temporally limited to a single year (2014-2015) and may not represent long-term trends.
- Spatial coverage is constrained to the specific voyage track of the RV Polarstern.
