More needs to be done to better understand rapidly changing Arctic landscapes that are sinking as climate-driven permafrost thaw penetrates deeper, according to new research by University of Alaska Fairbanks scientists and others. International climate monitoring organizations have no uniform standard for measuring ground subsidence, leading to an underestimation of thaw depth and therefore an […]
The massive 2015 flooding of the Sagavanirktok River in northern Alaska had immediate impacts, including closure of the Dalton Highway for several days, but it also contributed to longer-term ground subsidence in the permafrost-rich region. That’s the finding by assistant professor Simon Zwieback at the University of Alaska Fairbanks Geophysical Institute in a study published […]
Coastal erosion and land subsidence driven by permafrost thawing may lead to extensive seawater inundation in several northern Alaska communities by 2100, according to research by a University of Alaska Fairbanks geomorphologist. Louise Farquharson, a research assistant professor at the UAF Geophysical Institute, made the long-term projections for the communities of Point Lay, Wainwright, Kaktovik and […]
