Helheim 2006

An investigation of glacial earthquakes

Photos from the maintenance and data download trip

This page contains some photos from our trip (July 22-25, 2006) to download data and perform maintenance at the network of GPS stations we installed at Helheim Glacier, East Greenland, in late June.
