The Extreme Ice Survey (EIS), based in Boulder, Colorado, uses time-lapse photography, conventional photography and video to document the effects of global warming on glacial ice. It is the most wide-ranging glacier study ever conducted using ground-based, real-time photography. Starting in 2007 the EIS team installed as many as 43 time-lapse cameras at a time at 18 glaciers in Greenland, Iceland, Alaska, Canada, the Nepalese Himalaya (where cameras were installed at Mount Everest in 2010), and the Rocky Mountains of the U.S. The cameras shoot year-round, during daylight, at various rates. The team supplements the time-lapse record by occasionally repeating shots at fixed locations in Iceland, Bolivia, the Canadian province of British Columbia and the French and Swiss Alps.
