A high-precision radar instrument left Southern California for Iceland today to create detailed maps of how glaciers move in the dead of winter. This will help scientists better understand some of the most basic processes involved in melting glaciers, which are major contributors to rising sea levels. The image is on a small part of the Hofsjökull ice cap in Iceland, which encompasses several glaciers. The fan at upper left is part of a glacier called Múlajökull.
