Dr Roger Clark

Roger took a Combined Honours BSc in Earth Sciences and Physics at Leeds, then a PhD on the upper mantle seismic structure beneath the British Isles, at Leeds and AWE Blacknest. Following this, he spent 8-10 years developing and applying, with Graham Stuart, new approaches in processing of land seismic data and operating a small consultancy/contracts group working on a large fraction of all UK land exploration. At the same time, he pursued research interests in the seismic monitoring of underground nuclear test-ban treaties. In 1988 a UK university consortium, organised from Leeds, deployed the first modern seismic station in the former USSR allowed to record nuclear explosions at close (<1000-1500 km) range, accelerating a pivotal aspect of verifying arms control treaties.

Since joining the academic teaching staff, and thereafter leading the Master’s in Exploration Geophysics, his research has been aligned to quantitative analysis of seismic amplitudes, in the contexts of resource exploration, near-surface site investigation, and, currently, cryosphere settings. His particular interest is in measurement of seismic attenuation, quantified by the Seismic Quality Factor, Q – an important parameter in signal processing tools that optimise seismic reflection imaging, a petrophysical characteristic in its own right, and, in ice, a direct proxy for temperature.  He has also contributed to a diverse range of other applied geophysics investigations, including archaeological, engineering, and hydrogeological studies.

He has contributed to outreach and community activities such as working with NGOs, journal editorship, and student-facing activities in the European Association of Geoscientists & Engineers (EAGE).  In 2013, he was awarded Honorary Membership of the EAGE in recognition of his contribution to applied geophysics education.
