A Mid-European Decadal Isotope-Climate Record from 15,500 to 5000 Years B.P.
Oxygen-isotope ratios of precipitation (δ 18 O P ) 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 be...
