What is Turbulence and Why Do We Care?
Presented by Dr. Donald Webster - January 23, 2013

In the first webinar of this three-part series, Dr. Webster takes us, step-by-step, through the physical aspects of turbulence, something we see everywhere. We learn how turbulence works in the world, and how it is observed and measured. In his talk, Don shows us the scales at which turbulence occurs by using images and videos of things familiar to us: worldwide oceanic currents, breaking waves and even crabs trying to find food. The purpose of this webinar is to not only break down the tough physics behind this ever-present phenomenon, but to set the stage for observing the interaction of biological organisms with turbulent flow. These topics will be introduced in follow-up webinars by Dr. Jeannette Yen (“From Cosmos to Copepods - How Does Turbulence Impact Different Scales?”) and Dr. Peter Jumars (“How Does Turbulence Shift Advantage For the Tiniest Ocean Creatures?”).
