During his academic career, Graham Westbrook has held 28 research grants and contracts and has participated in 23 marine geological and geophysical research cruises. He has taught a wide range of subjects at both BSc and MSc level in the fields of geophysics and tectonics and has supervised 25 research students.

Research interests

After working initially on the structure of the crust and upper mantle at subduction zones, Graham Westbrook's research focused on the structure and tectonics of accretionary wedges and on the role of fluids in governing the tectonic processes of these wedges. Over recent years, his primary research activity has been on submarine gas hydrate, using seismic techniques to investigate the distribution of methane hydrate in continental margins and the structures through which methane is brought to the seabed, such as gas/fluid-escape chimneys, and using numerical modelling to simulate the processes by which methane hydrate forms near the seabed and by which gas released from dissociating hydrate migrates through the sediment. He has worked on submarine gas hydrate since he was co-chief of ODP Leg 146, which drilled gas hydrate off Vancouver Island and Oregon. He coordinated the EU FP5 project HYDRATECH, which developed seismic techniques for the quantification of methane hydrate in continental margins, using data acquired from sites off west Svalbard and the Storegga region off Norway, and in 2006 he organised two high-resolution tomographic experiments with ocean-bottom seismometers, conducted on fluid-escape chimneys off Norway, as part of the HERMES project. Since 2008, he has been involved in an investigation of the effect of climate change on the stability of Arctic submarine hydrate off Svalbard. In these projects off Norway and Svalbard, he worked in collaboration with colleagues from other universities and research institutes, principally the University of Southampton - National Oceanography Centre and Ifremer. His collaboration with Southampton and Ifremer continues, through research funded by NERC that employed very high-resolution seismic and CSEM imaging of hydrate and gas off Svalbard in 2011 and 2012.
