Dr. John Colosi, who holds Professorships at both the Naval Postgraduate School (NPS), and UCSC (Adjunct), will be the featured keynote speaker for the Seventh Annual Grayson H. and Jane Dishong Rayborn Lecture Series in Physics and Astronomy with a lecture entitled, "The Sonic Sea: From Climate Change to National Security, Listening in on our Blue Planet.”

Explore the captivating world beneath the waves in this talk inspired by Dr. Colosi’s book "Sound Propagation through the Stochastic Ocean." He'll unravel the mysteries of marine life's acoustic physiology and delve into methods used to study ocean sounds, from small to planetary scales. Focusing on the Arctic, where traditional methods face challenges, he'll touch on the broader implications for national and global security. Drawing from the legacy of his mentor Walter Munk, the father of Tactical Oceanography, join us for a journey into the symphony of the sea and the fascinating realm of ocean acoustics.
