Permafrost-Hydrogeologic Regimen in Two Ice-Free Valleys, Antarctica, from Electrical Depth Sounding
Electrical resistivity field measurements and subsequent laboratory analyses of the electrical properties of soils and rocks, both frozen and unfrozen, are used to describe the type and configuration of permafrost in Wright and Taylor Valleys, Antarctica. Rock and soil samples saturated with potable...
