Jakobshavn Isbrae, Greenland

I'm back in Greenland for two different project. First we went to Ilulissat on the West Coast to use a new ground based radar for measuring the speed of the world's fastest glacier: Jakobshavn Isbrae. The glacier continues to retreat and is now as far back as it has been since observations started. It is also flowing very fast, with speeds exceeding 50 meters per day at the front.

One thing we are interested in is how the speed of the glacier changes when it calves into the ocean. In the field, we run cameras at high intervals (10 seconds) to capture calving events. In past years, these events have been dramatic. Now they seem to be smaller, but much more frequent. Here is one calving event. The light is a bit low, since it happened at 2 AM.
