Box 21468, Juneau, AK 99802; (907) 586-2030. and M.F. The latter period has featured less calving particularly in the last decade and is a result of greater summer melting and a higher snowline by the end of the summer, which has averaged 1250 m since 2003 vs 1050 m prior to that (Pelto et al, 2016). Boyce et al (2007) note the glacier had two period of rapid retreat one in the 1940s and the second beginning in the 1990s, both enhanced by buoyancy driven calving.

Now a new analysis shows that Taku has lost mass and joined the rest of the retreating glaciers. 41, No. Once a test pit is dug, assessment of retained snow water equivalence (SWE) is determined through snow density and ice layer measurements. Survey Report. In 1990 the Taku Glaciers AAR and MAA were still strong enough (82 and 62) for Pelto and Miller to conclude that the Taku Glacier would continue to advance for the remaining decade of the 20thcentury..

Several tidewater glaciers in the southern part of Spitsbergen are retreating because of rising air temperatures. If a glacier experiences more melting than snow accumulation in a season, the glaciers snowline migrates to higher altitudes. This provides an independent measure of mass balance.

Igneous quartz-rich, dioritic rocks known as tonalite are commonly eroded by the Mendenhall Glacier and are found in glacier sediments around Mendenhall Lake. In September 2018 the snowline reached 1550 m the highest elevation the snowline has been observed to reach any year. The end of summer snowline is the equilibrium line altitude where mass balance at the location is zero. The natural-color images above show the glacier on August 20, 2014, and August 9, 2019.
