Episode Description: Whales whisper, volcanoes rumble, and fish sing at sunset. In this episode of Oceanography, host Clark Marchese explores the science of underwater sound with marine biologist and bioacoustics researcher Dr. Jesús Alcázar-Treviño. You'll learn how toothed whales use echolocation to hunt in the deep sea, how volcanic eruptions reshape marine soundscapes, and why some whales may be mistaking plastic for prey. We also dive into the impacts of human-made noise—like shipping and seismic testing—on marine ecosystems. With fascinating stories from the Canary Islands and deep-sea research insights, this episode is your gateway into the hidden world of ocean acoustics and marine conservation.
