UAF researchers map Alaska effects of melting permafrost

As average temperatures rise, two University of Alaska Fairbanks researchers are mapping permafrost’s impact on Alaska. Vladimir Romanovsky and David McGuire are members of a team working to identify worldwide regions susceptible to thermokarst.
Romanovsky said the natural process is the result of what happens when ice-rich permafrost begins to melt.
“The water may run away or stay in place, but because of that, surface of land is subsiding,” Romanovsky said. “This subsi
