VARIABILITY IN FIRN DENSIFICATION RATES ON THE TAKU GLACIER, SOUTHEAST ALASKA
Firn densification modeling plays an important role in several types of glaciology and ice dynamics studies. However, some processes that affect firn densification rates have not yet been thoroughly described. Prior studies of firn densification processes have widely focused on the effects of temperature and accumulation; the impact of regional ice stress on these processes has been largely overlooked. Using standard methods of seismic refraction on the Taku Glacier in Southeast Alaska, we have created firn density profiles for areas of both low and high strain. Through comparison of these profiles, we are able to analyze the effects of strain on firn densification rates for a particular glacial setting.
