Last meeting - November 4, 2017 at Boundary Oak Golf Course, Walnut Creek

Michael Stocker, bioacoustician and Renaissance man, described the acoustic environment of the oceans. Animals use sound to navigate, identify themselves, maintain social groups, locate food and in some cases stun it for capture, identify predators and other dangers, find mates, and otherwise survey their surroundings. Sounds have always been present in the oceans arising from animals, water movement, geologic forces, weather, and other natural phenomena, but man-made sound is an ever more pervasive feature, with potentially far-reaching effects. Michael played numerous recordings of natural ocean noise and man-made sounds. Learn more at the website of his organization, Ocean Conservation Research <>. Photo from <> by Peter Joseph.
