Jul 11, 2013 • Glaciologist Mauri Pelto, a professor at Nichols College in Massachusetts uses Landsat to look at nearly three decades of glacier change on the Juneau Icefield in his recent blog post, From a Glacier’s Perspective.

He begins:

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 Alberta. Given the difficult weather conditions that produce the 4000+ square kilometers of glaciers, this was not a task that could be done comprehensively. Here, we examine the changes from the August 17, 1984 Landsat 5 image to the June 21, 2013 image from newly launched Landsat 8.+ continue
