The application of direct-current resistivity prospecting methods to ice masses
Direct-current resistivity prospecting methods have been used but rarely in the past in physical investigations of icecaps and glaciers. However these methods have the advantage of using light-weight and inexpensive equipment that is simple to operate. As part of the geophysical program of the Arcti...

Direct-current resistivity prospecting methods have been used but rarely in the past in physical investigations of icecaps and glaciers. However these methods have the advantage of using light-weight and inexpensive equipment that is simple to operate.
