From Cosmos to Copepods - How Does Turbulence Impact Different Scales?
Presented by Dr. Jeannette Yen - January 30, 2013

Dr. Jeannette Yen takes us on an intriguing adventure, from the cosmos to copepods, in the second of a three-part webinar series on the concept of turbulence. A follow-up to Dr. Donald Webster’s presentation that focused on introducing turbulence and why it matters to us, Dr. Yen shows us how turbulence can occur at various scales and the similarities we see between islands forming vortical wakes in the atmosphere and zooplankton moving through the water column. Her talk is jam-packed with multimedia content, from incredible close-up images of copepod feeding appendages to videos of her research observing mating behavior in various copepod species. She incorporates aspects of Dr. Webster’s webinar and prepares the audience for the last and final installment of this series presented by Dr. Peter Jumars, which will focus on the ocean's tiniest organisms.

Dr. Jeannette Yen received her Ph.D. in Oceanography from the University of Washington in Seattle. Her research interests include small-scale biological-chemical-physical interactions in plankton, especially the behavior and signal recognition by marine zooplankton: fluid physics of signal structure, neurophysiological basis of signal detection, consequences on feeding ecology, functional morphology, biochemical composition, and reproductive strategies - of marine plankton, especially copepods, from tropical to polar oceanic regions.
