Age determination and radionuclides of sediment cores from the Western Atlantic

The CO2 record for air bubbles from the Byrd Station ice core suggest a drawdown in the ocean-atmosphere carbon reservoir during the early Holocene. Such a drawdown would require a corresponding increase in the CO3= ion concentration in the deep sea. We report here the results of a search in Atlanti...
