Exploring the Relationship Between Permafrost Degradation and Remotely Sensed Snow Seasonality in the North Slope of Alaska Ksenia Lepikhina and Jeffery Thompson (mentor) Earth Lab - Project Permafrost ksenia.lepikhina@colorado.edu

What is permafrost? https://www.wunderground.com/climate/permafrost.asp Impacts of a Warming Arctic; Alexander, Cherry; Symon, Carolyn; Corell, Robert; 2004

How does change affect us? Warping the ground Burning methane bubbles http://www.worldculturepictorial.com/blog/content/arctic-heats-thaws-permafrost-sealing-methane-greenh http://www.nrcan.gc.ca/science/story/11700

Purpose of research http://www.scienceinschool.org/2012/issue22/permafrost

Expected Results

Methods Snow seasonality (moderate resolution optical satellite based imagery) Active layer depth (point data)

2016

2016

2016

Summary data for first snow - full snow season Number of days after August 1, the year before the snow year shown in the table.

Internship Goals Implement a data management scheme Metadata Snow seasonality and active layer depths ** Data used for this project is obtained from the Geographic Information Network of Alaska’s (GINA) MODIS satellite.
