Simon Zwieback, PhD
Simon Zwieback’s office has little space in which to maneuver on this particular day in the West Ridge Research Building at the University of Alaska Fairbanks. Boxes of equipment and supplies dot the floor in preparation for a research trip to the far north in Alaska. It will be the first of three visits the assistant professor will make to Toolik Field Station for a project to determine areas that have ice-rich permafrost. The project draws on data from the European Space Agency’s Sentinel-1 satellite constellation and downlinked and made available through the Alaska Satellite Facility, which operates as one
