Alexandria, Va. – Join EARTH Magazine and guest writer Irina Overeem on an expedition that pitted a team of scientists against rapid erosion in the Arctic. Overeem transports readers to the edge of the North Slope of Alaska where her team explored the effects of rapidly thawing permafrost on cliff erosion — a  process that’s resulted in an annual average of 15 meters of shoreline recession in recent years. The researchers expect that, with continued warming, the processes responsible for erosion will only accelerate.

It is important to document and understand Arctic coastal erosion processes because they have immediate impacts on local infrastructure. Time-lapse photography and detailed analysis helped the team identify what triggers massive blocks of the coast to fall into the Beaufort Sea.
