Bölling  

Definition

  • The Bølling oscillation, also Bølling interstadial, was a cool temperate climatic interstadial between the glacial Oldest Dryas and Older Dryas stadials, between 14,700 and 14,100 BP, near to the end of the last glacial period. It is named after a peat sequence discovered at Bølling lake in central Jutland, Denmark. It is used to describe a period of time in relation to Pollen zone Ib—in regions where the Older Dryas is not detected in climatological evidence, the Bølling–Allerød is considered a single interstadial period. The beginning of the Bølling is also the high-resolution date for the sharp temperature rise marking the end of the Oldest Dryas at 14,670 BP. Roberts (1998) uses 15,000. A range of 14,650–14,000 BP calibrated has been assigned to the Bølling layer of the excavation at Lake Neuchâtel, Switzerland, 1992–1993. The Oxygen isotope record from Greenland ice includes the Bølling warm peak between 14,600 and 14,100 BP. Most of the recent dates available fall within a few hundred years of these. Of the two periods, Bølling and Allerød, Bølling is the warmer and came on more suddenly. During it sea level rose about 35 m due to glacial melt. Ice uncovered large parts of north Europe and temperate forests covered Europe from 29 deg. to 41 deg. north latitude. After some pioneer vegetation, such as Salix polaris and Dryas octopetala, hardwoods, such as Quercus, and softwoods, Betula and Pinus, spread northward for a brief few hundred years.
