Major surge of the Bering Glacier

Authors


Abstract

Definitive evidence has been obtained in the last few weeks documenting that a new and potentially major surge of Bering Glacier is beginning. According to Bruce F. Molnia, U.S. Geological Survey, Reston, Va., and spokesperson for a USGS research group that includes Austin Post, Dennis Trabant, and Robert Krimmel, as of June 28, several hundred kilometers of the glacier were involved in the surge, displaying intensive crevassing, displaced moraines, ice overriding previously exposed bedrock, and pressure ridge development (Figure 1).
