William Armstrong
Glaciology, Arctic Earth Systems, Remote Sensing
Assistant Professor, Geological and Environmental Sciences, Appalachian State University
Overview
I am an earth scientist who uses remote sensing, numerical modeling, and field studies to answer questions in glaciology and Arctic earth surface processes. I am a passionate educator in the classroom and the field who strives to integrate geospatial data, quantitative thinking, and broadly applicable/employable skills into all my courses.

Misperceptions about career opportunities are cited as a leading cause for the earth sciences being the least diverse STEM field (Sherman-Morris & McNeal, 2016), with little sign of improvement over the past 40 years (Bernard and Cooperdock, 2018). We will develop educational materials and a costume and green screen-based K12 outreach activity to familiarize young people (with particular focus on underrepresented groups) on viable careers in earth science, many of which feature more lab or computer-based work than field work.

The evolution of glacier speed in a warming world affects the timing and amount of glacier ice that is transferred to downstream river systems and the global ocean. Glacier motion is sensitive to meltwater, and recent work suggests that climate warming will slow glacier motion due to more efficient drainage of the glacier bed (e.g., van de Wal, 2015; Tedstone et al., 2015). However, these conclusions are drawn from relatively short time spans and we know that a glacier's sensitivity to water inputs can evolve over decadal timescales (Iken & Truffer, 1997). Our project will build on pioneering work (Raymond, 1971) to investigate how the dynamics of Athabasca Glacier have evolved over the past 50 years as the glacier has thinned and retreated in response to climate change.
