caption_attribution_description: English: Schematic of use of active and passive sonar to detect bubble leakage from seabed (seeps, carbon capture and storage facilities) and gas pipelines (originally from Leighton, T.G. and White, P.R. (2012) Quantification of undersea gas leaks from carbon capture and storage facilities, from pipelines and from methane seeps, by their acoustic emissions, Proceedings of the Royal Society A, 468, 485-510 (doi: 10.1098/rspa.2011.0221)).
context_page_description: Timothy Grant Leighton FRS FREng FMedSci is the Professor of Ultrasonics and Underwater Acoustics at the University of Southampton. He is the inventor-in-chief of Sloan Water Technology Ltd., a company founded around his inventions.
  He is an academician of three national academies. Trained in physics and theoretical physics, he works across physical, medical, biological, social and ocean sciences, fluid dynamics and engineering. He joined the Institute of Sound and Vibration Research at the University of Southampton in 1992 as a lecturer in underwater acoustics, and completed the monograph The Acoustic Bubble in the same year. He was awarded a personal chair at the age of 35 and has authored over 400 publications.
context_section_description: Leighton invented:
  radar for the detection of buried explosives, hidden bugging devices, and for the location of buried catastrophe victims (in avalanches, mudslides, collapsed buildings etc.)
  the world's only sonar system capable of detecting objects in bubbly water (key, for example, to protecting services, cargo and aid shipping in conflict zones). - mine detection is often an ongoing problem long after conflict has reduced and civilians return to former conflict zones (key collaborator: Paul White)
  a number of systems for detecting objects buried in the seabed
  and, in collaboration with the National Oceanography Centre, one sold by Kongsberg for archaeological and civil engineering purposes. Various collaborations are looking at ways of providing clean water from waste in Low- and Middle-Income Countries, including mentorships of young entrepreneurs in Africa.
