NASA aerial survey of northern permafrost begins this summer

NASA survey of northern permafrostNorthern permafrost stores about twice the amount of carbon in the atmosphere.  As the Arctic warms the permafrost thaws and the carbon is exposed to microbes who convert it into methane and carbon dioxide which ultimately enter the atmosphere.  To collect better data on the extent to which northern permafrost is melting, this summer nine aircraft will fly over Alaska in the U.S. and the Yukon and Northwest Territories in Canada.  This is part of the Arctic-Boreal Vulnerability Experiment (ABoVE), a $100 million, 10-year, NASA-led campaign to study the permafrost.  Paul Voosen et al., Science  07 Jul 2017: Vol. 357, Issue 6346, pp. 12-13 DOI: 10.1126/science.357.6346.12
