Roger Clive Searle (born 24 October 1944 in St Ives, Cambridgeshire, Huntingdonshire) is an English geophysicist, known for using sonar imaging in research on the geology and geophysics of the ocean floor.
He was from 1970 to 1973 an assistant professor at Haile Selassie University in Addis Ababa.
[1] Searle is known as a leading pioneer in the processing and use of the GLORIA sidescan sonar system, developed in the UK.
[10] Later in his career, he studied the effects of mantle hot spots on plate accretion and, with co-workers, found some of the first evidence that extreme asymmetry can occur in short-term plate accretion.
[1][11] He has done important research on seamount morphology and origin, the geodynamics of oceanic core complexes, and ultra-slow rates in seafloor spreading.
[4] One of the triumphs of the BRIDGE programme was mapping the bathymetry of the Reykjanes Ridge.
