Response of a marine-terminating Greenland outlet glacier to abrupt cooling 8200 and 9300 years ago [PDF]

, 2011
Long-term records of Greenland outlet-glacier change extending beyond the satellite era can inform future predictions of Greenland Ice Sheet behavior. Of particular relevance is elucidating the Greenland Ice Sheet's response to decadal- and centennial ...
