THE INITIATION AND DEVELOPMENT OF A JÖKULHLAUP FROM THE SUBGLACIAL LAKE BENEATH THE WESTERN SKAFTÁ CAULDRON IN THE VATNAJÖKULL ICE CAP, ICELAND
Results from investigations of a jökulhlaup from the subglacial lake beneath the Western Skaftá cauldron in the Vatnajökull ice cap are reported. Following thermal drilling into the lake in June 2006, the lake temperature was measured and the elevation of the ice shelf covering the lake recorded wit...
