The Deep-Sea Podcast

What has no jaw, inverted horizontal teeth, saggy skin and can produce litres of suffocating slime when touched? it’s the episode you’ve been waiting for… The hagfish special is here.

Our short and to the point PRESSURISED version of episode 20. If you don't have time for the full episode and want to get right to the science without any of our waffle, this is the place to be! Read the show notes and find the full episode here: https://www.armatusoceanic.com/podcast/020-love   It’s February, the month of love and there’s love in the deep ocean too. We talk reproductive strategies in the deep sea with Professor Craig Young, Dr Autun Purser and Dr Mike Vecchione. How do you find a mate in the sparsely populated deep ocean? How can egg and sperm meet when you are fixed growing on a rock? How can your babies disperse and find a suitable habitat, especially if you live in a rare habitat like a hydrothermal vent? We find the solutions to all these problems and more.   Feel free to get in touch with questions or you own tales from the high seas on: podcast@armatusoceanic.com   We are also on Twitter: @ArmatusO Facebook: ArmatusOceanic Instagram: @armatusoceanic Read the show notes and find out more about us at: www.armatusoceanic.com   Glossary Abyssal plain – the wide-open spaces of the deep sea, most of the planet Filter feeder – animal that feeds by filtering the water e.g., sponge Gametes – the reproductive cells, eggs and sperm Gonad – the organ that produces the gametes Hadal trench – the deep-sea trenches more than 6 km deep Hermaphrodite – both male and female simultaneously Sessile – animals that cannot move (opposite of mobile)   Links Massive icefish breeding ground paper Ecosystems of the World – Craig has a great chapter on reproduction in this book Paper - Estimating dispersal distance in the deep sea: challenges and applications to marine reserves Paper - Reproduction, Larval Biology, and Recruitment of the Deep-Sea Benthos Paper - Hadal snailfish reproduction   Credits Theme – Hadal Zone Express by Märvel Logo image - PRESSURISED logo

Read the show notes and find the full episode here: www.armatusoceanic.com/podcast/044-alan-takes-over   It finally happened… we brought you an episode which was recorded almost completely offshore. With Dr Thom in the Bounty Trough and the Professor somewhere in the Pacific, this episode is quite the wild card. Whilst Thom has been busy crocheting fishing nets (that’s science folks), Alan was left to take the reins and he decided to go a little off-piste. We bring it back to the good old days with one of Alan’s (in)famous rants. This one is titled: When does the sea become the deep sea, and why it needs to be changed. Expect to hear about the history of why we decided what makes the deep-sea ‘deep’, and why it might not make sense anymore in our modern world. We’d love to hear your thoughts on this and whether you agree with Alan.    Finally, we check in with a key individual in the online deep-sea community space: Jeff Day. Jeff’s been on our radar for years with his immense knowledge of deep-sea cephalopods and we thought we’d finally hand him the mic. He talks to us all about his love of deep sea creatures and how he contributes to the field in unconventional ways. We’re really trying to make this project self-sustaining so we have started looking for ways to support the podcast. Here’s a link to our page on how to support us, from the free options to becoming a patron of the show.   Thanks again for tuning in, we’ll deep-see you next time!   Check out our podcast merch here!

On the other end of that line is Mike Vecchione, the expert on cephalopods. We talk giant and colossal squid (to audible groans from Mike); the bigfin squid (Magnapinna), most famous for being the squid with the long trailing arms that’s often used as an example of terrifying deep-sea creatures, but also a species, genus and Family that Mike described and would love more sightings of.   We are also on: Twitter: @DeepSeaPod Facebook: @DeepSeaPodcast Instagram: @deepsea_podcast   Read the show notes and find out more about us at: www.armatusoceanic.com   Credits Theme – Hadal Zone Express by Märvel Edited by - Georgia Wells   #deepsea #marinebiologist #marinebiology #podcast #marianatrench #science #magnapinna #colossalsquid #giantsquid #gigantism #scicomm #deepseafish #deepseacreatures

From being repeatedly thrown off your bed in a storm, to seeing blue whales out of your porthole, working at sea doesn’t leave you short of stories. And with Dr Thom and the Professor both heading offshore soon, they thought what better time to share some of their sea stories. From tips on how to hold your pee for 12+ hours, to tales of typhoons, this episode is jam-packed with real-life tales from decades of working offshore.

We think of the deep sea as an eerily quiet and spooky place but that isn’t completely true, animal communication, seismic activity, human noise and even the sound of rain and waves from 10 km above. We chat with undersea audio expert Dr David Barclay about the fascinating audio properties of the deep ocean.

In our third episode of The Deco-Stop we begin to tackle the immense topic of eco-anxiety.

Read the show notes and find the full episode here: https://www.armatusoceanic.com/podcast/016-biodiscovery   We are in desperate need for new bioactive compounds. Super bugs are on the rise as evolution finds a way of thwarting our antibiotics. We are also continually on the hunt for compounds that can fight disease, ease suffering or get your teeth super white. The natural world has been experimenting for millions of years and has come up with solutions far more elegant than we could come up with. The ocean, and in particular the deep ocean, may be the best place to look for new compounds but is this a threat to the ocean? It is often mentioned alongside seabed trawling, climate change and mining as a threat to the deep ocean. Should we call it bioprospecting or biodiscovery and what’s the difference? If most of the world’s ocean belongs to everyone, who owns a discovery? How do we ensure that developed nations, who are better equipped to benefit from a discovery, don’t leave developing nations out? Are companies really patenting naturally occurring compounds? If we find something exciting, what is the process for it becoming the next wonder drug? While they both agree that looking for new compounds in the deep sea sounds good, Alan and Thom are soon stumped by the complexities of actually making that happen in a fair and sustainable way. Luckily, they can call on Professor Marcel Jaspars, head of the Marine Biodiscovery Centre to help us through the practicalities of biodiscovery but also its political and ethical complexities.

It feels like technology and access is really accelerating in both spheres. Don calls in to teach us about the amount of water in our solar system and the potential new job title – Planetary Oceanographer.   When samples or access to a vehicle is limited, how can we ensure that resources are shared fairly? We have seen it lead to disagreements on ships. With something as singular and precious as a Mars rover, how are its objectives planned? Evan Hilgemann, mechanical engineer and Curiosity Rover driver with NASA’s Jet Propulsion Lab (JLP) joins us to share how a rover is managed. We chat about the parallels between exploring mars and exploring the deep sea, the similar issues we face, what we can learn from each other and most excitingly, where is technology heading on both fronts!

But this time we are talking about the deep sea… Innnnnn Spaaaaaaaace! It turns out there is deep sea outside of earth in our solar system in the ice-covered moons of the gas giants. How likely are they to contain deep-sea life completely independent from the life that originated on earth? Thom chats with astrobiologist Kevin Peter Hand, author of Alien Oceans: The search for life in the depths of space, and director of NASA’s Ocean Worlds Lab. What are the best candidates for alien life in our solar system? What could that life be like and why does our own deep ocean provide a perfect test bed? It turns out that the early versions of the vehicles which may some day explore these ocean worlds are already in development. Thom chats with Casey Machado, Research Engineer at Woods Hole Oceanographic Institution about the Orpheus AUV, the first generation of such vehicle and a new asset to the exploration of our own deep ocean.

We learn more about the mysterious world of deep sea gelatinous organisms. From jellies to sea slugs.

Natural history collections, huge archives of carefully curated specimens, are an invaluable tool for the scientific community. They are also a place where the public get to interact with active research and meet scientists. Forget what you’d imagine working in a museum to be like, no two days are the same.

We learn all about deep-sea drilling and the geology deep under the ocean floor.

It turns out there is deep sea outside of earth in our solar system in the ice-covered moons of the gas giants. How likely are they to contain deep-sea life completely independent from the life that originated on earth?

On this special episode of The Deep-Sea Podcast, we talk all things submarines.

Natural history collections, huge archives of carefully curated specimens, are an invaluable tool for the scientific community. They are also a place where the public get to interact with active research and meet scientists. Forget what you’d imagine working in a museum to be like, no two days are the same.

What can we learn about the deep sea from genetic analysis? Drs Heather Ritchie and Johanna Weston help us understand describing new species and detecting creatures from their DNA alone. Alan finds a way of sending us audio logs from the field and we have our first interview from over 10km deep!

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 planetology 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 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 are joined by James Cameron (yes, that one) to talk about solving the problems of working deep with new technology.

We impact the deep sea in many ways we don’t realise. Some are deliberate, some are accidental, some we didn’t even notice at the time.

It’s the holidays so we decided to get together, have a few drinks and tell some stories from life at sea.

Our world is rapidly changing. As we move away from fossil fuels and our use of electronics increases, demand is climbing for a handful of metals key to the manufacture of modern technology. Mining the deep sea may meet these demands but is probably the most contentious issue the community is facing right now. Is there a net benefit for the deep sea; funding research and understanding, addressing climate change, and encouraging developing nations? Or is the deep sea too fragile and too unknown to be responsibly exploited? We bite off far more than we can chew by taking on this issue in a deep-sea mining special episode. Luckily, we have some guests we can call on to help us understand the issue. Professor Jeffrey Drazen of University of Hawai`i at Manoa explains just what deep-sea mining is and its ecological impacts. We then speak with Michael Lodge, secretary-general of the International Seabed Authority (ISA). The ISA, comprised of 167 member states and the European Union, regulates and controls all mineral-related activities in the open ocean – that’s the majority of the planet! We also have current news and a chat with Don Walsh, who of course it turns out, has first-hand experience with the complexities of mining in the ocean.   You can submit your own ‘tails from the high seas’ about an experience you have had offshore or pose us a question on: podcast@armatusoceanic.com   Theme – Hadal Zone Express by Märvel (http://marvel.nu/)   Links ECO Magazine Deep-Sea Heroes: http://digital.ecomagazine.com/publication/?i=683954&ver=html5&p=22 Scary bigfin squid video: https://youtu.be/L8xXnVkOGsA Bigfin squid paper: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0241066 Eel swarm: https://www.sciencedirect.com/science/article/pii/S0967063720302107 ISA website: https://www.isa.org.jm/ DeepData: https://www.isa.org.jm/deepdata UNESCO report: http://whc.unesco.org/en/news/1535/ #deepseamining #deepsea #mining #ManganeseNodules #manganese #PolymetallicNodules #Polymetallic #ISA #InternationalSeabedAuthority #MichaelLodge #LawOfTheSea #HighSea #InternationalLaw #conservation #EnvironmentalImpact #seamount #HydrothermalVent #ProtectedArea #ProtectedHabitat

In this episode we explore the power of storytelling and complete the arc of our first five episodes: science communication and perception of the deep sea. We talk with multiple New York Times bestseller Susan Casey (https://susancasey.com/) about telling a good story and engaging people with a narrative, while still being scientifically accurate. Don Walsh (https://en.wikipedia.org/wiki/Don_Walsh) is kind enough to record his thoughts on the importance of good storytellers, which of course also contains a story we never knew about Don.   Storytelling is an incredibly powerful tool, but it can be a difficult one to wield. Alan talks of some experiences where the public perception of a story was not what was expected but also the risk of not telling the story at all and of assumptions being made.   We have our regular returning segments: Recent news, which seems very squiddy this episode; tails from the high seas, where Alan is imprisoned in a seaman’s mission; and Thom tries out a new segment about the history of some deep-sea animal names.   You can submit your own ‘tails from the high seas’ about an experience you have had offshore or pose us a question on: podcast@armatusoceanic.com   Theme – Hadal Zone Express by Märvel (http://marvel.nu/)   Links The description of the roundnose grenadier from 1765: https://www.ntnu.no/ojs/index.php/DKNVS_skrifter/article/download/710/642 An image of the Grenadier cap: https://en.wikipedia.org/wiki/File:Prussian_Grenadier_Cap.jpg An image of the grenadier fish: https://en.wikipedia.org/wiki/Abyssal_grenadier#/media/File:Coryphaenoides_armatus.jpg Frankie Fulleda’s podcast, Hard Candy & Fruit Snacks: https://podcasts.apple.com/us/podcast/hard-candy-fruit-snacks/id1532914761

It’s the October episode and that means it’s our Halloween Spooktacular, what better time to turn the spotlight on ourselves and wonder why humanity seems to have an intrinsic fear of the deep sea. Glenn Singleman (https://en.wikipedia.org/wiki/Glenn_Singleman) joins us to give a psychological explanation for why we feel differently about the deep sea and seem to have an aversion to it. Even some of the best documentaries seem to change their wording when talking about the deep sea. We give Don a quick call to get his thoughts on fear, as that’s something he’s always asked when talking about the first dive to the deepest point. Finally, we have a Tails from the High Seas from Heather Stewart who, after running from some bad weather, found herself in the middle of a military exercise.

Can we use art to help people engage with the deep sea? We stop trying to explain things and let artist Alex Gould (alexandragould.co.uk) help us see deep-sea animals for the first time all over again. We talk about the aesthetic of deep-sea fish, is it shaped by our expectations? Can we save the blobfish from bullying? Can art help us with the horror of tongue eating parasites and fish absorbing their boyfriends? Sponsor Armatus Oceanic

On January 23, 1960 Don Walsh and Jacques Piccard were the first people to dive to the deepest point in the ocean, Challenger Deep. Would you believe that Don's full of other stories at least as interesting as that?

‘We know more about the moon than the deep sea’ isn't just a bad analogy, it’s wrong. We talk scientific writing and Alan confesses why, after becoming the world’s deepest Brit, he was hunched emerging from the sub. podcast@armatusoceanic.com Absence of sharks Music Harvey Jones

Just a quick hello to introduce the podcast (and check I know how to do this). Official episode 1 coming soon.   Dr Thom https://twitter.com/AllLittleFishes
