010 - Here be monsters with Tyler Greenfield
04/02/21 • 78 min
1 Listener
Tales of monsters persist to this day and there’s no better place to hide them than in the deep sea. We are joined by paleontology student and cryptozoology blogger Tyler Greenfield to look at some of the most famous sea monsters and see if there is any truth to the stories. We discuss megalodon, globsters, plesiosaurs/Nessie and all manner of strange carcasses that wash up from time to time.
We have a good hard listen to The Bloop and I call upon an expert in the undersea calls of marine animals, Nicky Harris. She also has a tale from the high seas for us... a rather grizzly bit of nature in action. People in the front row will get wet.
Also in this episode, we talk about glowing sharks, the largest bioluminescent vertebrate. Soft robotics to the planets deepest places and Alan picks a fight with a polar bear, taking on The Octonauts’ very own Captain Barnacles.
Finally, we hear from Don Walsh, who shares some ocean myths that went on to have a grain of truth.

009 – Geology with Heather Stewart
We are both biologists and a little bias toward the deep-sea critters, but the deep ocean contains a wealth of geological discoveries, after all, it is the geology which creates the deep sea.
We catch up the latest news, including life discovered 100s of km under the ice, slowing water currents, vampire squid history and the rules of naming something new, be it a species or an undersea feature.
We then have a chat with geologist and explorer (and friend of the show) Heather Stewart about the geology of the deep sea and how we produce maps of the ocean floor. Why do people talk about how little of the ocean has been mapped when we can clearly see it is all mapped on google earth?
What about some of the more unusual features that we see on the deep seabed in Google Earth, are those roads and pyramids? I have a chat with ‘my mate DaveTM’, David Howell, about marine archaeology and looking for sunken human settlements.
Finally, we hear from Don Walsh, who recollects the time he used the bathyscaph Trieste to deploy devices to listen out for nuclear tests.

011 - Genetics with Heather Ritchie and Johanna Weston
Alan is stranded out in the Pacific and Thom is left to present a show on genetics, a topic so confusing to him it may as well be magic. Luckily, friends of the show are on hand. Dr Heather Ritchie is tricked into co-hosting and we talk to Dr Johanna Weston about the things we can learn about the deep sea from genetic analysis.
Alan has found a way to get audio logs to us (pretty sure a Holtzman Wave isn’t a thing) and shares what he has been up to out at sea – it turns out, a lot! Listen in for lots of exclusives. This includes an interview with sub-pilot Tim Macdonald from inside the Limiting Factor at over 10,000 m depth. We are pretty sure this is the world deepest interview. The Deep-Sea Podcast lives up to its name, the deepest podcast around.
In recent news we discuss how our immune system doesn’t recognise deep-sea bacteria (and how that may be a good thing) and Thom gushes about his new favourite thing... blackwater photography.
Don Walsh tells us about inspecting ex-soviet reactors and discovering he is standing on top of a running one and Thom and Heather tell the tale of acquiring a -80 °C freezer in New Caledonia.
