Jack studies ice sheets and glaciers on Earth and Mars in order to understand fundamental geologic processes and climate history. In most cases, Jack uses radar sounding combined with TDEM, lidar, photogrammetry, and high-resolution imagery. Observations are acquired on the surface, by airplane, and from orbit. Jack develops instrumentation and works with others to conduct multi-sensor campaigns. He also uses paleomagnetism to study polarity reversals and excursions of the Earth’s magnetic field.
