Yamal Permafrost Hole Update For May 2015


An overpass on 18 May 2015 by Worldview 3 Optical Satellite (0.4 m ground-resolution) shows the Yamal Hole filling with water. The clarity of the water allow us to see into the funnel shaft before the level of light penetration reduces to darkness. In the next year we will study the Yamal Permafrost Hole by remote sensing and satellite ranging. We have begun a satellite reconnaissance survey for other recent permafrost features in Alaska and Siberia.
