Surface underway measurements of carbon dioxide partial pressure, salinity, temperature, and meteorological variables were collected aboard the RV Polarstern in the South Atlantic Ocean from November 2013 to March 2014. The dataset includes atmospheric and aquatic CO2 fugacity, sea surface temperature, salinity, barometric pressure, wind speed, and wind direction. Data were collected by researchers from the Alfred Wegener Institute, Groningen University, and the Royal Netherlands Institute for Sea Research using a CO2 gas analyzer and other instruments.
Use Cases
- Calculate air-sea CO2 flux using partial pressure of carbon dioxide in water and atmosphere, along with wind speed data.
- Analyze correlations between sea surface temperature, salinity, and the partial pressure of carbon dioxide in water.
- Model oceanic carbon uptake in the South Atlantic using time-series of CO2 fugacity and concurrent barometric pressure measurements.
- Study seasonal marine meteorology patterns by examining wind direction and speed records from the voyage track.
Strengths
- Includes simultaneous measurements of both atmospheric and aquatic CO2 partial pressure (fugacity).
- Covers a continuous 4-month time-series from a specific research cruise in the South Atlantic Ocean.
- Combines chemical (CO2, salinity), physical (temperature), and meteorological (wind, pressure) variables for integrated analysis.
Limitations
- Spatial coverage is limited to the track of the single RV Polarstern cruise.
- Sample size and temporal resolution (row count) are unknown from the provided metadata.
- Data is from a single season (austral summer) and does not represent annual cycles.
