Variability of sea-ice conditions in the Fram Strait over the past 30,000 years

Juliane M|[uuml]|ller , Guillaume Mass|[eacute]| , R|[uuml]|diger Stein & Simon T. Belt

Sea ice is a critical component of the climate system: variations in sea-ice cover affect the albedo of polar regions, and also the rate of deepwater formation. Changes in the sea-ice cover of the North Atlantic Ocean are thought to have been related to abrupt climate changes throughout the last glacial termination, but reconstructions of sea-ice conditions are rare.
