This month is a fun one (maybe not if you love cetaceans) as we’re covering whale falls!
This month is a fun one (maybe not if you love cetaceans) as we’re covering whale falls!
That’s right, dead whales and the ecosystems they create on the seafloor. Professor Craig smith joins us to talk all about the stages of decomposition, the key species that whale falls support, and some truly wild tales from the high seas.
We finally answer the big question, what smells worse: a dead whale or a dead deep-sea sponge? The answer might not be what you expect. We also hear from a couple friends of the show, including Shelly Raiden, who may have found one of the earliest comparisons of the moon and the deep sea, and Otis Brunner, who talks us through his research on the back of our last episode on hydrothermal vents.

In other news, consuming deep-sea water lowers cholesterol (this one is definitely, absolutely, 100% true), there’s a new deep-sea documentary premiering at Sundance and we made our first 30p (and a pint)! This newfound success has pushed us to release another Deco-Stop episode on neurodiversity in science coming to you next month!
