According to a recent study, a hidden valley buried beneath the ocean floor in the north sea was quickly craved out around the 'death throes' of an ancient ice sheet near the end of the ice age about 20,000 years ago. Subterranean structures can give clues about the mode of ice sheet reaction towards climate change.
