You are invited to the capstone presentation by Dean Maraldo, “Accelerated Retreat of Coastal Glaciers in the Western Prince William Sound, Alaska”, on April 30th at 2:00 pm CST.
Presentation abstract: Analysis of historical maps and multi-temporal Landsat imagery suggests most coastal glaciers in the western Prince William Sound have retreated since the end of the Little Ice Age, with an unprecedented period of accelerated retreat after 2004/06. Area measurements for 43 glaciers were derived from digitized outlines, and lengths were calculated using a semi-automatic, GIS-based algorithm. From 1950 to 2018, the total area of all glaciers decreased by 316 km2, with 32% of the loss occurring after 2004/06. Declining winter precipitation before 2004/06, followed by increasing summer precipitation and annual temperatures, may have facilitated accelerated melting.
