UAF faculty will come back and scan the village again in a year or two to track how the ground has changed.
Nunapitchuk is one of 10 communities in the Yukon-Kuskokwim (Y-K) Delta that will be scanned and rescanned again in the coming years. That will help researchers understand a root question: how is permafrost in a changing climate affecting the ground surface and, in turn, everything that sits on top of it?
“Once we can take another model, say after the summer or next fall, then when that changes the deck detection, where we can see ‘Oh, this used to be 1 foot above river level and now it's 0.7 feet above river level,’” Delue said. “Then you can start to examine: ‘Was that because of permafrost that we're seeing those specific changes? And what's the rate of that change?’”
