Bering Glacier has started to surge again following a 7-month period of minor retreat and near-stagnation. Part of the terminus advanced about 750 m between May 19 and June 1.
Bering—the largest surging temperate glacier on Earth—recently experienced a major, 17-month-long surge that ended in September 1994. That surge displaced the terminus by a maximum of about 9 km and caused a substantial increase in iceberg production. It also covered the islands within Vitus Lake completely or partially with ice [Eos, 74, 321–322, 521; Eos, 75, 549] and caused significant changes in the lake's size, bathymetry, hydrology, and water chemistry. The latest surge is overriding two of these islands, which are home to many species of waterfowl, including the endangered dusky snow goose, at the peak of the nesting season.
