Arctic coastal erosion 2010

One can watch a month of coastal melting in one minute. This movie is a time-lapse of 15 min shots taken at Drew Point along the Beaufort Sea. Drew Point is about halfway between Point Barrow and Prudhoe Bay on the North Slope of Alaska.This particular movie was taken in August 13th-September 11th, 2010.

The coastal bluffs you see in the ovie are about 4 m high, the blocks that erode away were measured to be 10.5m long. A large volume of the permafrost is just ice (uto 70%), the rest is fine sediment and peat as well as grass that grows in the upper 35 cm (the active layer).

There are polar bears passing by!
