Summary: Oxygen-isotope ratios of precipitation (delta 18OP) inferred from deep-lake ostracods from the Ammersee (southern Germany)
provide a climate record with decadal resolution. The record in detail shows many of the rapid climate shifts seen in central
Greenland ice cores between 15,000 and 5000 years before the present (B.P.). Negative excursions in the estimated delta 18OP
from both of these records likely reflect short weakenings of the thermohaline circulation caused by episodic discharges of
continental freshwater into the North Atlantic. Deviating millennial-scale trends, however, indicate that climate gradients
between Europe and Greenland changed systematically, reflecting a gradual rearrangement of North Atlantic circulation during
deglaciation.
