Soil and permafrost distribution, soil characterisation and soil vulnerability to human foot trampling, Wright Valley, Antarctica
Soils and shallow permafrost in Wright Valley, Antarctica were mapped at a scale of 1:50 000 to depict their spatial distribution, and sampled to determine the main drivers for the soil classification. In the cold desert of Wright Valley the Gelisol order of Soil Taxonomy was used to classify the …

Impact of permafrost dynamics on Arctic groundwater ow systems with application to the evolution of spring and lake taliks
Groundwater ow in permafrost is restricted to unfrozen zones, known as taliks. There is an interaction between groundwater ow and heat ow, because the permafrost distribution determines the occurrence of groundwater, but groundwater also contributes to advective heat transport in uencing the …

Rock Glacier Distribution, Activity and Movement, Northern Absaroka and Beartooth Ranges, MT, USA
… hand digitized in a GIS and evaluated using 11 distributional characteristics. Beartooth rock glaciers were found to occur at higher elevations, receive more precipitation, and were subjected to colder temperatures. Additionally, logistic regression analysis was used to examine the predictive …
