YouTube Description
as posted by the channelThis week Xanthe Walker and her team from Northern Arizona University is heading out into Denali National Park to measure just how deep recent fires have burned into the soil. Getting a handle on how much new carbon Arctic fires are releasing to the atmosphere is a critical part of NASA’s Arctic Boreal Vulnerability Experience (ABoVE) campaign.
Climate change in the Arctic and Boreal region is unfolding faster than anywhere else on Earth, resulting in reduced Arctic sea ice, thawing of permafrost soils, decomposition of long- frozen organic matter, widespread changes to lakes, rivers, coastlines, and alterations of ecosystem structure and function. NASA's Terrestrial Ecology Program is conducting a major field campaign, the Arctic-Boreal Vulnerability Experiment (ABoVE), in Alaska and western Canada, for 8 to 10 years, starting in 2015. ABoVE seeks a better understanding of the vulnerability and resilience of ecosystems and society to this changing environment.
