| Abstract |
At the end of the last ice age, rising atmospheric CO2 levels coincided with a decline in radiocarbon activity, suggesting the release of highly radiocarbon-depleted CO2 from the deep ocean to the atmosphere. These authors present radiocarbon records of surface and intermediate-depth waters from two sediment cores and find an decrease in radiocarbon activity that precedes and roughly equals in magnitude the decrease in the atmospheric radiocarbon signal during the early stages of the glacial–interglacial climatic transition. |
