DOVE, short for Drilling Overdeepened Alpine Valleys, is an ICDP project that drilled into buried valleys carved by glaciers in the Swiss Alps. At sites near Tannwald and Basadingen in Switzerland, scientists reached depths of about 730 meters of drilling and recovered about 400 meters of intact rock cores. These deep, overdeepened valleys were formed when warm-based glaciers pressed against the mountains, and subglacial meltwater carved troughs below the surface. By dating the rocks and sediments and studying the cores, researchers aim to pin down when past glaciations happened and how far they extended. This helps reveal how fast glaciers erode mountain ranges and shape the landscape, which matters for understanding climate history and how landscapes respond to changing ice. The findings also provide important context for assessing the safety of radioactive waste disposal sites in former glaciated regions. Overall, DOVE seeks to illuminate the long history of ice in the European Alps and the forces that sculpted them.
