image: This shows the massive calving front of the second most southerly tributary of the Upernavik Icestream, Northwest Greenland. The fast-flowing ice stream is evident as the heavily crevassed zone adjacent to the slowermoving ice, which appears as a smoother surface. The rolled-over iceberg in the center of the picture is roughly 200 meters across.This image relates to a paper that appeared in the August 03, 2012, issue of Science, published by AAAS. The paper, by K.H. Kjær at Natural History Museum, University of Copenhagen in Copenhagen, Denmark, and colleagues was titled, “Aerial Photographs Reveal Late–20th-Century Dynamic Ice Loss in Northwestern Greenland.” view more
