Listen to the numbers. From an ice-breaker in the Arctic to the piano keyboard, scientific indicators become music and gestures, a narrative made of science and digital art. An experimental tale of the emotion at the heart of the research. This is how Judy Twedt creates data-driven soundtracks from sea ice.

In this second episode, we explore the sound of ice and what microbes have to say to us. In the words of microbiologist Donato Giovannelli, we discover that "the whole planet is run by microbes, and they don't care much about what humans do: the planet will keep functioning either way, with new animal species, new ecosystems." The question is whether and how humans will still play a role.
