Scientific Reports / Millennial-scale glacial climate variability in Southeastern Alaska follows Dansgaard-Oeschger cyclicity
A stalagmite from Prince of Wales Island grew episodically between ~75,000 and ~11,100 yr BP; interrupted by seven hiatuses. Hiatuses most likely correspond to permafrost development and a temperature drop of up to 5 °C from modern conditions. Intervals of calcite deposition place tight constraints...
