Episode 2: How Not to Get Lost in the Ocean

The anthropause has shown us that we’re too noisy for the ocean’s animals. By now, we know the ocean is anything but silent. Fish grunt, whales moan, reefs roar with the deafening sound of snapping shrimp, and even natural sounds like waves and rain can be heard throughout the ocean. But people have taken it to the next (decibel) level, with global shipping, oil and gas rigs and exploration, sonar, and fishing and recreational boats. Can we learn to be good neighbors and turn the noise down? On this final episode of The Sound Aquatic, we try to find out. Find show notes and a transcript at hakaimagazine.com/the-sound-aquatic.

Whale clans teach and transmit culture using their own unique dialects. “Culture” is a tricky thing to define—anthropologists still don’t totally agree what comes under its umbrella. But by any measure, it’s getting clearer and clearer that humans aren’t the only ones who have it. And below the waves you’ll find some of the most famous and mysterious nonhuman cultures of all.

Swiping right in the deep blue sea. Ah, l’amour. Finding a mate is a big part of life for all animals and those beneath the waves are no exception. Of course, this search for love often involves—you guessed it—sounds. From the booming grunt of a fish trying to lure a lucky lady to his lair, to the mournful moan of a whale, sending out deep, loud sounds across ocean basins to potential mates from far, far away, this episode of The Sound Aquatic listens in on love beneath the waves.

Marine animals that navigate through whispers, songs, grunts, or clicks. Sound travels far underwater. And it travels fast, too—about four and a half times faster than it does through air. So it’s no wonder animals use sound to find their way around. Imagine being able to “see” your way through pitch black depths just by listening to the waves, other creatures, or even ambient noise, such as mudslides; or being able to make clicks and use their echoes to build a picture of the space around you. In this episode, we look at how marine animals from whales to fish (and even tiny fish larvae) use sound to navigate their world, using it for everything from finding a good place to call home to the next bite to eat.

Eavesdropping on marine motormouths during the world’s most expensive experiment. When Elin Kelsey and the producers of The Sound Aquatic podcast first gathered in early 2020 to create a podcast about ocean sounds, they had no idea what an amazingly unique year 2020 would be for anyone listening in on the ocean. In this episode, Elin takes a deep dive into the wonderful world of fish sounds and finds out what makes the Anthropause—as some experts are calling it—the world’s most expensive experiment.
