Abstract

Glacial-interglacial variations in atmospheric pCO2 remain unexplained. Here, the authors show that the Norwegian Sea, an modern area of intense CO2 uptake, acted as a CO2 source during the terminations of Heinrich stadials 1, 4 and 11, sometimes characterized by rapid increases in atmospheric pCO2.
