A 10,000-Year Record of Arctic Ocean Sea-Ice Variability-View from the Beach
We present a sea-ice record from northern Greenland covering the past 10,000 years. Multiyear sea ice reached a minimum between similar to 8500 and 6000 years ago, when the limit of year-round sea ice at the coast of Greenland was located similar to 1000 kilometers to the north of its present positi...
