Interdisciplinary Science at the Bering Glacier. The Bering Glacier is the largest and longest glacier in continental North America and is the largest temperate surging glacier on earth. The Bering Glacier has surged at least six times during the twentieth century, and the last surge occurred in 1993-1995. The Glacier is currently retreating, and scientists from MTRI have been conducting research at the Glacier during a period spanning almost a decade.
