NCEI Accession 0157471 contains surface underway observations of carbon dioxide partial pressure, salinity, and other variables from the North Atlantic Ocean. Data were collected by researchers Arne Körtzinger and Tobias Steinhoff from GEOMAR and Leibniz Institut using a Carbon dioxide gas analyzer and other instruments aboard the R/V POSEIDON. Measurements span a nearly five-year period from May 2010 to April 2015.
Use Cases
- Calculate air-sea CO2 flux using the difference between Partial pressure of carbon dioxide - water and Partial pressure of carbon dioxide - atmosphere.
- Analyze correlations between SEA SURFACE TEMPERATURE, SALINITY, and the fugacity of carbon dioxide in surface water.
- Model seasonal and interannual variability of oceanic pCO2 in the North Atlantic Ocean using the 2010-2015 time series.
- Validate satellite-derived sea surface temperature or salinity products with in-situ measurements from this dataset.
Strengths
- Time series covers a multi-year period from 2010-05-31 to 2015-04-07.
- Includes directly measured atmospheric and aquatic CO2 partial pressure, a key variable for flux calculations.
- Data collected by established oceanographic institutions (GEOMAR, Leibniz Institut) using a dedicated CO2 gas analyzer.
Limitations
- Exact sample size (row count) and spatial resolution are unknown from the provided metadata.
- Geographic coverage is limited to the cruise track of the R/V POSEIDON in the North Atlantic Ocean.
- Data collection ended in April 2015, limiting analysis of recent trends.
