1000 year-long flood frequency record for the North-western Alps (Lake Oeschinen)@en

Here, we present an annually-resolved record of summer flood frequency from the varved (annually laminated) sediments of proglacial Lake Oeschinen (46 30 N-7 44 E, 1580 m, NW Swiss Alps) back to AD 884. This dataset is produced based on the occurrence of flood event layers in the sediments. The chronology of the sediment record is based on multiple varve counts and validated with historical floods chronicled in written documents (back to the 14th century), 210Pb, 137Cs and 14C AMS dates.
