Science for Alaska Lecture Series: Feb. 25

From the icefields to the oceans: the impacts of melting glaciers on Alaska's landscapes and ecosystems"

Anthony Arendt
Research Associate Professor of Glaciology
UAF Geophysical Institute

Abstract:
Every year, Alaska's glaciers produce enormous amounts of freshwater that flows across landscapes and ecosystems. The magnitude and timing of freshwater delivery to these systems can affect salmon spawning locations, ocean circulation patterns, and the feasibility of hydropower generation. In this talk I will explore how scientists are studying these processes, and explain what kinds of changes we can expect in light of projected future climate variability.
 
 
Biography:
Dr. Arendt is a research associate professor in the glaciology department at the University of Alaska Fairbanks and Geophysical Institute. He received both his bachelor’s and master’s degrees in Earth and atmospheric sciences from the University of Alberta in Edmonton Canada. He went on to receive his doctorate in geophysics here at UAF.
 

After receiving his doctorate, Dr. Arendt accepted a post-doctoral fellowship at NASA Goddard Space Flight Center in Greenbelt Maryland working with Gravity Recovery and Climate Experiment (GRACE) satellite data and using glacier and climate models to predict responses of glaciers to climate change. He then returned to UAF and the GI to assess glacier contribution to rising sea level using remote sensing and field observations of glaciers and ice sheets, with a focus on satellite gravimetry and satellite and airborne altimetry.
