Imaging Drumlin Architecture with Electrical Resistivity

Januka Attanayake, Yongping Chen, Rory Henderson, Zhao Zhao


Geomorphologists may use the knowledge of interior structure of drumlins to infer finer-scale dynamics of glaciers. An electrical resistivity imaging study was carried out to investigate the interior architecture of a drumlin near UCCT seismic station located in the premises of the University Connecticut. Apparent resistivity measurements collected from an 81 m-long dipole-dipole electrode array oriented along the longer axis of the drumlin were inverted to obtain a subsurface model. The model consists of four layers of different resistivity values. These results are used to infer a glacial depositional sequence of younger upper till and older lower till separated by a transition layer. Evidence for a basement crystalline rock core was not found at the maximum penetration depth of 17 m.
