Ghostly glimpses of Earth's glacial past

摘要

The footprints of long-gone glaciers and icebergs are now frozen in time in a stunning new collection of images of Earth's seafloor. The Atlas of Submarine Glacial Landforms is a comprehensive, high-resolution atlas of underwater landscapes that have been shaped by glaciers, largely in polar and subpolar regions, and provides a comparative look at how glaciers, ice and related climate shifts transform Earth. Kelly Hogan, a marine geophysicist with the British Antarctic Survey and an editor of the atlas, presented it April 26 in Vienna at a meeting of the European Geosciences Union.
