TITLE: A Scintillating Problem: Sound Propagation through the Stochastic Ocean
``… the intensity of the signal received from one second to the next will not be constant; it fluctuates often by a factor of 10. Indeed the presence of fluctuations is perhaps the most constant characteristic of sound in the sea’’
This talk will review the present state of our understanding of the nearly 70 year old subject of sound propagation though the stochastic ocean, where key contributions have come from (1) developments in physical oceanography such as the Garrett-Munk internal wave spectrum and spicy sound speed structure, (2) technological advances in source and receiver capability, (3) advances in computing and data processing power, and (4) developments in theoretical physics such as Feynman path integrals, transport theory, and dynamical systems theory. New challenges exist aplenty including gaining an understanding of arctic and high latitudes, the mixed layer and upper ocean, and monitoring various aspects of climate change. For progress, significant contributions from all four of the aforementioned fields will be required.
