In this online program, dive into the sea to explore the different ways humpback whales use sound to communicate. In the 1950s, the famous underwater filmmaker Jacques Cousteau described the ocean as a "silent world" - but the ocean is anything but silent! Novel remote acoustic technology allows scientists to listen with our ears and study the structure and function of whale songs. You will learn about who makes sounds and how we can turn sound into useful information for ecological and conservation studies.
