DESCRIPTION:Prof. Ben Kneller\, University of Aberdeen\nTwo main types of 
 buoyancy-driven flows occur in the oceans: river plumes\, driven by the bu
 oyancy of fresh water over seawater\, responsible for the dispersal of fin
 e sediment onto continental margins\; and turbidity currents which are neg
 atively buoyant\, driven by the presence of suspended sediment\, and can c
 arry sediment far into the ocean basins to form submarine fans\, which are
  the largest sediment accumulations on the Earth. Both of these types of f
 low are profoundly influenced by the stability of their boundaries with th
 e ambient fluid (expressed as a gradient Richardson number) due to the int
 erplay between the velocity gradient and density gradient.\nBio: Ben Knell
 er obtained his BSc in geology at University of Sheffield\, and his PhD fr
 om University of Aberdeen. He held post-doctoral positions at Leeds Univer
 sity and Liverpool University before obtaining a faculty position at Leeds
 \, where he worked on laboratory investigations of gravity currents as wel
 l as field geology on deep-water depositional systems. He moved to Univers
 ity of California at Santa Barbara in 2000\, working alongside numerical m
 odellers in Mechanical Engineering\, before returning to Aberdeen in 2004.
  Since 1992 he has run industry-funded research groups specializing in dee
 p-water systems and processes. He maintains a strong interest in geologica
 l fieldwork.
