It is the Department of Applied Mathematics’ pleasure to be hosting Harry Swinney from the University of Texas Austin for our final Boeing Distinguished Colloquium of the quarter! Dr. Swinney’s research has spanned a wide array of topics in nonlinear dynamics and pattern formation, based on conceptually simple table-top experiments that he and his group then interpret and model mathematically and numerically. Title and abstract of this week’s talk below.A reception in Lewis Hall will follow Dr. Swinney’s talk.
TIME: 4:00 PM, THURSDAY, MAY 11, 2017

Title: Dynamics and energetics of waves inside the oceans
Abstract: The ocean is stratified as a consequence of decreasing temperature and increasing salinity with depth. Much of the energy in the oceans is in internal gravity waves generated by tidal flow over ocean bottom topography. These waves can travel thousands of kilometers, and they play a major role in! ocean mixing and circulation. However, it is difficult to make accurate estimates of the conversion of tidal energy into internal wave energy because of the complexity of ocean topography and the constructive and destructive interference of the internal waves. This talk presents results from laboratory experiments, numerical simulations, and ocean and satellite observations that yield insight into internal wave dynamics and improve estimates of the total internal wave energy.
