How should the sea sound? And how does it sound if you're a fish, a dolphin or a shrimp? What are the noises made by marine animals? What are the impacts of sounds made by humans travelling across the oceans, diving deep to mine for resources, or even waging war across the water? 

In this episode, we hear what a happy coral reef sounds like, how Russia's war in Ukraine is hurting dolphin ears, and why slowing down ships could change everything for underwater acoustics. 

And at the end, we've put together an ocean sounds quiz. 

Guests of this episode are:

Nicolas Entrup, Director for International Relations at Ocean Care. 

Pavel Goldin, Leading Researcher at the Department of Evolutionary Morphology, Schmalhausen Institute of Zoology in Kyiv, Ukraine.
