Umesh Haritashya, Assistan Professor at the University of Dayton in Dayton Ohio has, with colleagues Mark Pleasants (also from Dayton University) and Luke Copland (from the University of Ottawa), remapped the velocity of the Tasman Glacier in New Zealand, and the Khumbu Glacier in Nepal and compared the results. They found that in the debris covered regions of the glaciers the Tasman had annual average velocity up to 140 m/year whereas the Kumbu Glacier measured up to an average of 70 m/year. The team used repeat-images from the ASTER satellite. The research has been published in Geografiska Annaler: Series A, Physical Geography
