(John) Stewart Turner FAA FRS (born 11 January 1930, in Sydney) is an Australian geophysicist. He was educated at North Sydney Boys High School [1] and Sydney University. He was awarded the 1851 Exhibition Scholarship to Cambridge. He completed his PhD thesis at Cambridge University in 1956 under the supervision of Sir G.I. Taylor. His thesis title was "Dynamical aspects of cloud physics".[2] He then worked for several years at the Woods Hole Oceanographic Institute, before returning to the Department of Applied Mathematics and Theoretical Physics, University of Cambridge. In 1975 he returned to Australia to become the Foundation Professor of Geophysical Fluid Dynamics, Research School of Earth Sciences, Australian National University 1975–1995. [3] [4] [5] [6] [7] [8] He is an elected Fellow of the Australian Academy of Science (1979) and the Royal Society (1982), and was awarded the Australian Academy of Science's Matthew Flinders Medal and Lecture in 1990. Since his retirement in 1996 has been Emeritus Professor and Visiting Fellow at the Australian National University.

His fundamental research of stratified fluid dynamics has made a significant impact[9] on the fields of physical oceanography, limnology and civil engineering. Key works include his 1979 monograph "Buoyancy effects in fluids".[10] his seminal work on plumes,[11][12] gravity currents,[13] entrainment in density stratified shear flows,[14] double diffusive convection,[15] mixed layer dynamics in the ocean[16] and the dynamics of ventilated flows.[17][18] Much of his work used laboratory experiment to understand the basic physics and scaling relationships. Some examples of his videos of double diffusive laboratory experiments are available on YouTube.[19]

(Note: He should not be confused with John Stewart Turner OBE FAA (1908–1991), the Australian botanist and plant physiologist.)
