The PI will carry out laboratory studies of fundamental                    fluid mechanical processes which have important geophysical                     applications.  He will carry out a laboratory study of the                      Rayleigh-Taylor class of instability in several geometries                      relevant to volcanism at mid-ocean ridges.  This will examine the               validity of recently proposed models of the segmentation observed               at mid-ocean ridges.  He will also investigate a novel in-                      stability of magma flow which is due to the strong variation of                 magma viscosity with temperature.  He will illustrate this                      instability in laboratory analogues of both fissure and lava                    flows and quantify the length and time scales over which it                     develops.
