Permafrost and Groundwater in the Fairbanks and North Pole Areas: What We Know, What We Don't Know, Future Needs

Ronnie Daanen and Abraham Emond

100 years of observations have illuminated the interaction of permafrost and groundwater. Early engineering resulted in practical solutions to dealing with permafrost.

Current research in Goldstream Valley and North Pole on the effects of permafrost on groundwater flow shows that new techniques can help identify permafrost and point to groundwater flow paths. These datasets can be used to inform state of the art physically based models used to reconstruct current permafrost distribution from historic climate and disturbance regimes. The models can also predict groundwater movement and change into the future.
