Daniel McGrath is member of a team of researchers at the Univeristy of Colorado that has been studying the effects of climate change on the Greenland Ice Sheet. They spend weeks at at time on the rapidly shrinking frozen island, descending deep in the ice shelf through holes formed by meltwater known as moulins. Petzl has been supporting their valuable research by providing them with crampons, ice axes, screws, ascenders, helmets, etc.
