With the Professor out at sea, Thom goes off the rails and finally gets his answers on cave biology. What are the similarities and differences between the deep-sea and cave ecosystems? How are they linked? Do we know more about the moon than cave biolo…. just kidding! We speak to the legendary Professor Thomas Iliffe, who has shaped the field of biospeleology (cave biology); discovering over 250 species, and 3 new orders (now you don’t hear that every day)! He talks us through the formation of these habitats, what dive surveys are really like, and how to discover the most fascinating of organisms. We also hear from Martin Pollizotto, a listener (and expert cave diver) on bioluminescence in cave systems (or a lack thereof).

We had a lot of deep-sea news this month! New species are being discovered, Alvin is back in the water breaking previous depth records, we have new tech AND some interstellar news!

We announce yet another exciting spin-off, The Deco-Stop, where we plan on chatting to guests about the more human side of science. We heard from listeners that they are fascinated by scientists as people and the stories they have to tell, so we’re excited to open up the space to talk about scientists as individuals, and the topics where science interacts with human issues.

In the very first episode of The Deep-Sea Podcast we let you know who we are and why we felt the world really needed a podcast about the deep sea. Alan rants about how the statement ‘we know more about the moon than the deep sea’ is not just a bad analogy, it’s plain wrong. Thom talks about how the quality of scientific writing is maintained. And our guest, Prof. Monty Priede, Editor-in-Chief of the scientific journal Deep-Sea Research Part I, talks about why there are no sharks in the abyssal zone.

After recovering from you-know-what last episode, we’re excited to complete our open-water/pelagic trilogy with this week’s guest Professor Justin Marshall. Justin is an expert on all things vision, and talks us through all of the intricacies and oddities of vision in the deep sea. We discuss how fish eyes have evolved in order to adapt to the darkness of the deep, and how exactly they are able to see bioluminescence. Justin’s research has been highly influential, so we ask him more about his discoveries of mantis shrimp vision, and how he found out that cephalopods were colour-blind!

We also couldn’t let him leave without getting some of the stories from his time living in the underwater habitat for weeks, and how this led to somewhat horrifying fungal consequences.

The deep sea has seen a flurry of activity this month with lots of news to cover! MBARI has released a fascinating new video of a deep-sea squid brooding eggs. We cover some more paleo-news with surprising historical deep-sea temperatures and the discovery of new brine pools in the Red Sea.

It wouldn’t be the Deep-Sea Podcast without checking in with Don Walsh as he talks us through the history of submarine windows. And we also hear from a listener and find out how snailfish got their name.

The deep sea has seen a flurry of activity this month with lots of news to cover! Our favourite cryptozoologist, Tyler Greenfield is at the epicentre of a monster-misunderstanding. Thom’s upset as yet another innocent fish is labelled the ‘ugliest creature ever seen’ by fishermen, but this time it’s a more familiar face. We also cover some more paleo-news with surprising historical deep-sea temperatures and the discovery of new brine pools in the Red Sea. Alan gives us an insight into his upcoming adventures at sea and we find out why he isn’t the biggest fan of documentarians.

It wouldn’t be the Deep-Sea Podcast without checking in with Don Walsh as he talks us through the history of submarine windows. And we also hear from a listener and find out what snailfish and The Kardashians have in common…

https://www.armatusoceanic.com/podcast/025-biolum

Last episode we learned about the pelagic zone, the largest habitat on earth, a boundless 3D space where enormous migrations take place. We learned that this isn’t a world of darkness but rather one of biological light, where bioluminescence is used to attack, to defend and to communicate. While producing your own light may seem alien to us, it is likely the most common form of communication on the planet.

To learn more about this world we speak with Edie Widder, who has studied bioluminescence for her whole career and used the same adaptations found in the animals to design her own equipment. She developed the Eye in the Sea, a camera system invisible to most deep-sea animals, and a lure which emulated a bioluminescent jellyfish, the e-jelly. The gear worked extremely well and along with a lot of behaviours observed for the first time this also captured the first footage of the giant squid, Architeuthis dux.

In recent news we talk about how plate tectonics impact our climate, what we can learn from the evolution of cave animals and generating power from the thermocline. Don Walsh tells us why these bioluminescent creatures are a nuisance to submarines.

We have a confession to make. We talk a big game about how we are busting myths, tackling deep-sea tropes and showing the deep ocean as it really is… but we have been guilty of one of the big ones. The deep sea is not just the bottom! Most of the deep sea, in fact, most of the habitat of this planet is the huge open 3D environment of open water or ‘pelagic’ water. In this staggering volume the planets largest migration takes place twice a day. Animals are locked in an evolutionary arms race, using their own light to deceive and trick. Finding a meal is rare, finding a mate is rare and life is without boundaries. These factors have led to some truly wild evolution.

We hear from Don about hunting for the 'deep scattering layer' (DSL) before we even knew what it was.

In recent news we cover Edith Widder and her new book Below the Edge of Darkness, underwater GPS through the power of a pong, following the yellow brick road to meet the deep-sea wizard and some lovely new footage of a highfin dragonfish.

Sorry that this episode isn’t the perfectly polished jewel that this show usually is. Thom’s family got a visit from both COVID and chickenpox so there hasn’t been the time or energy to edit as well as he usually does. But we couldn’t abandon you without an episode this month as some great stuff is still covered.

Last episode we leaned about the pelagic zone, the largest habitat on earth, a boundless 3D space where enormous migrations take place. We learned that this isn’t a world of darkness but rather one of biological light, where bioluminescence is used to attack, to defend and to communicate. While producing your own light may seem alien to us, it is likely the most common form of communication on the planet.

The gear worked extremely well and along with a lot of behaviours observed for the first time this also captured the first footage of the giant squid, Architeuthis dux.

In recent news we talk about how plate tectonics impact our climate, what we can learn from the evolution of cave animals and generating power from the thermocline. We hear from a listener about their bigfin squid archive. Larkin drops by to tell us what a ‘Tron Dolphin’ and Don Walsh tells us why those same Tron Dolphins are a nuisance to submarines.

We also tackle a couple of listener questions: Whatever happened to the word ‘nictoepipelagic’ which seems to have vanished from scientific writing? We also discuss parasites in the deep sea, how can they find a specific host when the animals are so spread out? We hear from Don about hunting for the 'deep scattering layer' (DSL) before we even knew what it was and find out where Larkin has been from her new vessel on the Gulf of Mexico.

In recent news we cover Edith Widder and her new book Below the Edge of Darkness, underwater GPS through the power of a pong, following the yellow brick road to meet the deep-sea wizard and some lovely new footage of a highfin dragonfish.

We also find ourselves talking about how the deep sea is portrayed in children’s books and learn that apparently zesty citrus and floral smells are associated with the deep ocean… who knew?!

Can we safely bring deep-sea organisms to the surface and keep them alive? Certain species, such as the giant isopods and giant Japanese spider crabs have been kept in aquaria in the past but the number of animals we can maintain long-term is quite small. The Monterey Bay Aquarium’s new Into the Deep exhibition has succeeded in keeping animals never before put on public display, some are even new to science. Not only that, but they have even had some success in getting them to reproduce! Figuring out what conditions these animals need and observing them over long periods will allow us to learn huge amounts about animals we usually only get a glimpse of. We talk with aquarists Ellen Umeda and Michelle Kaiser and life-support engineer Brian Maurer about the years of work that went into keeping these animals and giving the public a very personal deep-sea experience.

In the rest of the episode, Alan is back in the UK and we get to record in ‘the very quiet room’. We discuss data sharing and the complexities of charging for data that may otherwise not be taken, visiting the Explorers Club in New York and language barriers within science.

I also call Alan’s bluff and present him with a lovely Deep-Sea Podcast apron which he then proceeds to wear in Hell’s Kitchen in New York.

We hear from a listener about how the podcast helped them through a difficult time and answer a listener question about the danger of entanglement for undersea vehicles.
