Terrestrial evidence for a spatial structure of tropical-polar interconnections during the Younger Dryas episode
The Younger Dryas chronozone, recognised in northern high-latitude areas as a cold event between 11 000 and 10 000 C-14 yr BP (12 900-11 600 cal. yr BP), seems to manifest itself globally in different ways. Here, we examine well-dated stratigraphic sequences together with high-resolution proxy data...
