Ocean floor feeding and deep-sea research

One of the most hostile places to exist on Earth is the deep-sea floor. Light only penetrates so far, and beyond that is complete darkness where alien looking creatures thrive. But what do they eat down there? And how do humans perform deep-sea research? We borrow an excerpt from our sister podcast, “Coast to Canopy”, and join Rob Diaz de Villegas as he talks to three deep-sea researchers about life around methane seeps and hydrothermal vents, and the difficulties of studying ecosystems far beneath the surface of the ocean.
