Definitions for "Allerød Oscillation"
The Allerød period is a part of a temperature oscillation toward the end of the last glaciation, during which temperatures in the northern Atlantic region rose from glacial to almost present day level. The Allerød is a warm, moist Blytt-Sernander period named after a type site in Allerød municipality in Sjælland, Denmark (near Copenhagen), where deposits created during the period were first identified and published in 1901 by Hartz and Milthers. The Allerød corresponds to Pollen zone 2.
