Researchers (including C-DEBI Director Jan Amend) drilling a borehole through a glacier inadvertently triggered an outpouring of frigid water into a nearby river — providing an unusual chance to examine an enigmatic type of natural flood. Glacial floods, or jökulhlaups as they’re known in Iceland, are created by the sudden release of water from lakes beneath glaciers. Scientists have been puzzled over what causes these floods and why they occur regularly at certain glaciers. Read the full journal article in Geophysical Research Letters.
