Juneau Icefield Glacier Terminus Change from Landsat 5 1984 to Landsat 8 2013

The Juneau Icefield Research Program (JIRP) has been examining the glaciers of the Juneau Icefield since 1946. Until the NASA Landsat program began field measurements and aerial observations were the only means to observe the glaciers of the icefield. For more than 40 years it was Maynard Miller, U of Idaho, who led this expedition that has trained so many of today’s glaciologists, today it is Jeff Kavanaugh, U of …

The Allison, Brown and Stephenson Glacier have all retreated substantially since 1947 when the first good maps of their terminus are available. Fourteen Men by Arthur Scholes (1952) documents a year spent by fourteen men of the Australian National Antarctic …

Rwenzori Glacier Retreat-Loss

The Rwenzori Range,Uganda typically referred to as Mountains of the Moon have been rapidly losing their glacier cover. The small, steep glaciers descend the peaks of Mt. Stanley: 5111 m, Mt. Speke: 4891 m and Mt. Baker:4873 m. The Georg Kaser, University of Innsbruck visited the range twice in the early 1990’s to prepare maps of glacier change to compare to a 1906 map derived from documents of the Duke …
