Iceland

North Atlantic OA Mooring (68.0°N, 12.6°W)

Interannual variations in the partial pressure of CO2 (pCO2) and pH in the North Atlantic reflect environmental changes that affect the marine ecosystem. Quantifying and understanding this variability, particularly in a region where there is vast uptake of anthropogenic CO2 from the atmosphere is critical. The North Atlantic OA mooring will measure the variability in the Iceland Sea region, as reflected in ocean temperatures and salinities, and circulation. The mooring results enable us to quantify and understand the structure of, and changes in, the North Atlantic carbonate system as the inventory of anthropogenic CO2 continues to rise. By measuring pCO2 and pH, we are able to more accurately and precisely study the changes associated with ocean acidification. The observations will be made within the context the Iceland Sea carbon chemistry time-series (IS-ts) that has been conducted since 1983 by the  Marine Research Institute in Iceland.

The mooring was developed and deployed by the NOAA - Pacific Marine Environmental Laboratory with support from the Ocean Acidification Program (OAP) and the Climate Observation Program (COP).
