Using an Ice Augur in the Canadian Arctic (IMAGE) University of Massachusetts Amherst Caption Climate scientists Nicholas Balascio and Francois Lapointe working with an ice auger to drill in the 3.5m thick ice at South Sawtooth Lake, Ellesmere Island, Nunavut Territory, Canada. An ice auger extension is needed because the ice is so thick. Coring lake sediments can only be done after this tedious work, Lapointe notes. Credit Mark B.
