A new study of one of the biggest ice sheets from the last Ice Age contains a warning for our warming world.
, an international team of researchers used high-resolution imagery of the seafloor to see how the ice sheet changed over. They mapped out more than 7,600 small-scale landforms called “corrugation ridges” on the seafloor around where the ice sheet once stood. The ridges are less than eight feet high and are spaced around 82 to 984 feet apart. These types of ridges are believed to have formed when the ice sheet’s retreating margin moved with the tide.
“This shows how rates of ice-sheet retreat averaged over several years or longer can conceal shorter episodes of more rapid retreat,” study co-author and University of Cambridge glaciologist Julian Dowdeswell
