High-resolution records of past climatic changes during the last glacial have revealed a number of abrupt changes on time scales of decades or less. Climate models suggest that the deep ocean circulation has the potential to act as a pacemaker of such changes. Based on results from ice cores from both polar regions, and the reference to a common time scale(More)
Sea surface reservoir ages must be known to establish a common chronological framework for marine, continental, and cryospheric paleoproxies, and are crucial for understanding ocean-continent climatic relationships and the paleoventilation of the ocean. Radiocarbon dates of planktonic foraminifera and tephra contemporaneously deposited over Mediterranean(More)
Slowly accumulated (<5 cm kyr '1) and rapidly accumulated (5-20 cm kyr-1) sediments have been compared to define the initiation and termnation times of the most recent sapropel (S1) in the eastern Mediterranean Sea. The Ba/A1 ratio has been employed as a more persistent index of productivity than C • g. Accelerator mass spectrometry radiocarbon dating of(More)
