Surface underway measurements of atmospheric and aquatic carbon dioxide partial pressure, barometric pressure, wind speed, and wind direction collected aboard the research vessel POLARSTERN. Data was gathered by researchers from the Alfred Wegener Institute and Groningen University across multiple voyages in the Arctic and Atlantic Oceans from May to December 2015.
Use Cases
- Modeling air-sea CO2 flux using partial pressure of carbon dioxide in water and atmosphere alongside wind speed measurements.
- Analyzing seasonal trends in oceanic pCO2 across Arctic and Atlantic regions from the 2015 time-series data.
- Correlating atmospheric conditions, such as barometric pressure and wind direction, with surface water carbon dioxide levels.
- Calibrating or validating satellite-derived pCO2 estimates with in-situ measurements from the POLARSTERN cruises.
Strengths
- Multi-variable dataset includes key parameters for carbon flux calculation: pCO2 in air and water, wind speed, and barometric pressure.
- Data covers a 7-month time range across 2015, capturing seasonal variation.
- Geographic coverage spans multiple significant bodies of water including the Arctic Ocean, Barents Sea, and North Atlantic Ocean.
Limitations
- Exact sample size (row count) and data resolution (temporal/spatial) are unknown from the provided metadata.
- Data is from a single year (2015) and may not represent long-term climatic trends.
- Limited to surface measurements from one vessel's track, creating spatial gaps between cruise legs.
