The Deep-Sea Podcast

Our short and to the point PRESSURISED version of episode 45. 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/045-hagfish 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. Dr Thom is back from his stint offshore, and The Professor pretty much now lives in a submarine, but that hasn’t stopped them from finally reuniting to make this special episode all about hagfish. We’ve talked about them a lot on the show, and decided it’s time to pass them the mic. So expect lots of slimy stories, toothy tales and a whole load of hagfish trivia you never knew you needed. There’s lots of updates after so many recent deep sea expeditions, with Thom’s latest cruise discovering many new species and Alan sharing live updates from the sub. Keep up with their latest goings-on via twitter! We speak to the king of the hagfish, Professor Doug Fudge, who has been studying these critters and their (in)famous slime for decades. We ask all the interesting questions like: how do they make so much slime, do they have any predators and why do they look like that? 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!

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.

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.

Are you looking for a podcast episode that contains the return of the blobfish, golden crochet hooks and rare deep-sea squid? Well, look no further than this episode of The Deep-Sea Podcast! 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.

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. Dr Thom does make an appearance in this episode, giving us a run-down of how the research cruise is going (SPOILER: The blobfish is back). Plus, we hear about the original blobfish and how exactly it came to be an internet sensation, from the man who was there: new fan favourite, Andrew Stewart. 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.

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.

In deep sea news: Norway has decided to go ahead with deep sea mining, cold coral reefs are being discovered, and hoards of marine fungi have been found in the twilight zone! But more importantly than all of that: the Professor was awarded an OBE! His sword and noble steed are currently in the post (first class), and we’re hoping they reach him in Perth from the Palace. We’ve also started a new segment with long-time friend of the show, Andrew Stewart who has an interesting hobby of manufacturing cod-liver shark-liver oil. Expect more unexpected stories from Andrew in future episodes! Finally, we want to say thanks again for your support!

We chat with undersea audio expert Dr David Barclay about the fascinating audio properties of the deep ocean. As we are talking audio data on an audio medium, lets have some fun with a game of ‘what can we grenad-hear’ where Thom tries to guess the deep-sea sound.

THE DECO-STOP: A DEEPER LOOK INTO THE HUMANS BEHIND DEEP SEA SCIENCE AND TECHNOLOGY. This is our third Deco-Stop episode, and this time we’re focusing on eco-anxiety. We are currently in the midst of an ecological crisis, but eco-anxiety is something of a mental health crisis in response. Many of us who work in this space (and many of us who don’t) are feeling these emotions, including plenty of our listeners who have got in touch to share their experiences. As such, we’ve wanted to make this episode for some time, but during it’s production, it became a far bigger subject than we were ready for. One thing that did become apparent, is that this is a dangerous subject and it is something that can do real harm. In this episode, we share with you some stories of how different individuals have influenced their lives in a direct response to eco-anxiety. Plus, we hear from the perspective of a psychotherapist who specialises in the field of climate & eco-crisis psychology. However, this is not a list of answers, and the priority is your health and safety and as the listener. We hope that this episode offers an insight towards such a big and difficult topic. Whilst it won’t leave you with a complete set of instructions on how to fix the world, we hope you find it comforting that there is a huge number of people who are feeling the same as you are. It’s a lrngthy one, so grab a cup of tea, give your local tree a quick hug, and tune in to this beefy episode of the Deco-Stop.

That’s where most of our adventures happen, that’s where most of the exciting discoveries and firsts happen and it’s where we meet some of the most interesting people. We want you to have a great time at sea too and not be put off by a bad first experience. Poor packing or a faux pas could spoil the whole experience and we don’t want that. We put together some advice for your first trip. Forgive us if parts seem patronising, they are all things we have seen spoil someone’s trip and with everything else to worry about, it’s easy to forget the simple stuff. We chat with Larkin, a deck-hand turned youtuber about life at sea and sharing that experience through her videos. What is her average day like at sea and how’s the morning commute when your office is a small response vessel chasing a submarine 10,000 m below you?

"Exploration is curiosity acted upon." — Don Walsh In this month’s episode, we’re honouring the late great Don Walsh, who sadly left us this month. You may have noticed that we hadn’t heard from Don in a good few months. He had a couple of ops that required some getting over, but that wasn’t going to slow him down. In September he was going through the Northwest Passage, a trip he had attempted 2 previous times but had been scuppered by weather and vessel trouble. Don’s unwavering commitment to deep-sea exploration meant that the monthly sea stories were no longer possible but we weren’t going to let the legendary Don Walsh sneak off without some fanfare, not after everything he’s done for us. We were putting together a Christmas episode where we could share some drinks and stories with Don and give him a proper send-off. While we were sorting out dates that everyone could do, Don passed. 92, nodding off in his favourite chair at the remote home he loved, surrounded by nature. Over the last 3 years it’s been a privilege to have Don recount one of his endless list of stories with us every month, stories that always made us smile. In some attempt to raise a toast to him and all that he’s done for the community, we bring you this Don Special episode. He will be missed. Legend.

Our short and to the point PRESSURISED version of episode 16. 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/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.

These interesting whales have been seen diving to depths of 3000 m, which way exceeds the max depth of their more famous cousin, the sperm whale (who usually hang out at around 1500m deep). It also turns out that we as humans have something in common with these deep diving critters: the mammalian dive response. We hear from Dr Ryan ‘Beefy’ Beecroft, a sub engineer and keen free-diver, who explains to us what deep diving feels like when you are an air breather.

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!

So everyone has been pretty busy but we finally got round to finishing off our deep sea habitats series with this episode on submarine canyons. We talk with Dr Teresa Amaro, from the University of Aveiro in Portugal about these hugely important habitats in the deep sea and how they influence the fauna of the continental shelf. Plus, we get to hear the infamous story of when The Professor and Teresa docked in Lisbon during a cruise and Teresa was able to clear out a bar for the whole of the crew. Plus, the deep sea has been all over the news this month with lots of new papers being released. Magnetic bacteria have been found by the (phenomenally named) HYPER-DOLHPIN ROV, mysterious markings on the seafloor turn out to be face-planting fish, and scientists have been training jellyfish to navigate through assault courses (kinda). The Professor’s deep sea research lab have also been busy recently with lots of exciting videos coming out from their landers. Plus, one mystery creature has the whole team stumped.

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.

What do punk snails, turning 40 and Titipo the Little Train have in common? Thats right! The latest episode of the deep-sea podcast. We might be a little late this month but we’ve packed in as much as we can with this one. We’re covering all the latest deep sea news, including new deep sea habitats, octopus gardens and brand new amphipod species. Plus, we hear from Becca Nicholls about her experiences of working as a woman offshore, and how old superstitions are still very much a thing.

In her newest novel, Susan takes us on a journey through the history of deep-sea exploration, from the myths and legends of the ancient world to the scientists who are just beginning to understand the mind-blowing complexity and ecological importance of the quadrillions of creatures who live in realms long thought to be devoid of life.

It’s time for our submarine, or human occupied vehicle (HOV) if you’re posh, special. First we reunite ‘Vegemite and Haggis’ and talk to submarine pilot Tim Macdonald about his and Alan’s undersea adventures around Australia. Manganese nodule fields, gothic cathedrals, and an undersea UFO. We then speak with Patrick Lahey and Frank Lombardo of Triton Submarines, a bespoke submarine manufacturer, about privately owned submersibles. Initially as luxury pleasure craft but we soon find out that there is a wide range of reasons why someone would want their own sub. Throughout their careers they have had many incredible experiences, like seeing a sixgill shark give birth and communicating with bioluminescent organisms. The podcast wouldn’t be complete without checking in with Don Walsh. He tells us about the large commercial tourist submarines which have now produced more tourist submariners than the US navy.

Read the show notes and find the full episode here: www.armatusoceanic.com/podcast/012-natural-history-collections 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 and both the collections and the talented people who work with them are in constant demand. One day your helping design new swimwear based on shark skin, the next settling an argument at a fishing competition.

We are both biologists and a little biased 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 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.

On this month’s episode, we wanted to go deeper and darker than we’ve ever gone before… prepare the enter: the deep biosphere! We talk with Professor Mandy Joye about the vast microbial wonderland which is the deep biosphere. This ecosystem, which exists deep under the seabed, has only recently been discovered and research is just starting to reach some interesting conclusions. We lean about the importance of deep sea microbes and how they cycle through our planet. Professor Alan has been very busy this month with another world record to add to the collection. Not only did Thom and Alan break the world record for the world deepest fish back in 2014 (with a Mariana snailfish (Pseudoliparis swierei) being observed at 8143m in the Mariana trench). But, Alan beat his own record with this new snailfish seen at 8336m in the Izu-Ogasawara trench near Japan!

On this month’s episode, we wanted to go deeper and darker than we’ve ever gone before… prepare the enter: the deep biosphere! We talk with Professor Mandy Joye about the vast microbial wonderland which is the deep biosphere. This ecosystem, which exists deep under the seabed, has only recently been discovered and research is just starting to reach some interesting conclusions. We lean about the importance of deep sea microbes and how they cycle through our planet. We also discuss the Deepwater Horizon oil spill, as Mandy was a key researcher in understanding it’s widespread effects on the microbial community in the Gulf of Mexico. Professor Alan has been very busy this month with another world record to add to the collection. Not only did Thom and Alan break the world record for the world deepest fish back in 2014 (with a Mariana snailfish (Pseudoliparis swierei) being observed at 8143m in the Mariana trench). But, Alan beat his own record with this new snailfish seen at 8336m in the Izu-Ogasawara trench near Japan! We’ve also got newly discovered whalefalls, interesting uses for polymetallic nodules and historic oceanic treaty’s being agreed upon in this month in the news! Talk about a busy month, ey! 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!

Our short and to the point PRESSURISED version of episode 7. 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! 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. We talk about ways we have impacted the deep sea and touch on the huge problem that is marine plastic, a particular problem in the isolated Mediterranean Sea. His serene highness Prince Albert II of Monaco tells us about his experience diving to the deepest point in the Mediterranean, the Calypso Deep and his Beyond Plastic Med initiative. You can submit your own ‘tales from the high seas’ about an experience you have had offshore or pose us a question/comment on: [email protected] Theme – Hadal Zone Express by Märvel (http://marvel.nu/) Links Mercury paper Deep Mediterranean paper Beyond Plastic Med

Here’s our second episode of The Deco-Stop; a deeper look into the humans behind deep-sea science and technology. We’ve done our science dive, and now it’s time to decompress, and discuss tales at sea, career paths and the social & political aspects of deep-sea science. From Steven Hawking to Charles Darwin, neurodiversity and science have been intertwined throughout history. Neurodiversity is a term which refers to the variety in the cognition of the human brain and can include people who are on the autism spectrum, or who have been diagnosed with dyslexia, dyspraxia, and dyscalculia, among others. We wanted to talk on a very human level about the strengths and weaknesses of being neurodivergent in science and to also share with you some personal stories and assistive resources. Thom shares his own journey in the field, alongside many other pioneering colleagues. Living legend, Bob Ballard speaks with us about his perspective on being dyslexic and even attributes his career success (including the discovery of the titanic) to his gift. Friends of the show, Tom Tangye, Sophie McLellan and Cat Morgan also share their experiences of working in the field alongside being neurodivergent. They share how the industry, and the world in general, is changing to be more inclusive and understanding of everyone who thinks differently. We had such a great time making this episode, and we’re so grateful to everyone who spoke with us. Below you’ll find a whole host of resources that have been shared with us, and that we recommend ourselves! Let’s carry on this conversation, with colleagues, friends, and with those outside our inner circles. Be patient with each other, and trust that the world is changing, for the better. We are so excited about creating this space to talk more about the human aspects of deep-sea science, and would love to hear from you about your deep-sea journey! Check out our podcast merch here!

Our short and to the point PRESSURISED version of episode 6. 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! 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!

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, who may have found one of the earliest comparisons of the moon and the deep sea, and Otis, 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)!

We’re continuing on our iconic deep-sea habitat trilogy with the episode you’ve all been waiting for… HYDROTHERMAL VENTS! In this jam-packed episode we cover forgotten Christmas specials, lebensspuren, deep-sea sandwiches and climate crisis sea-shanties (and that’s only in the first 20 minutes)! We speak to the incredible Charles “Chuck” Fisher, a pivotal biologist in hydrothermal vent research, about these fascinating habitats and the organisms which exist there. We learn about the iconic tube-worms and their specialised adaptations to life in these extreme environments. Plus, Chuck does some of his own myth-busting and sets the record straight on a common tube worm trope. Don shares his own experiences of these impressive habitats (and the not-so-impressive lunches that came alongside them). Plus, we hear from you in the form of listener questions, children’s books and (another?!) deep-sea conspiracy theory. Buckle-up for a big one! Check out our podcast merch here! Which now includes Alan’s beloved apron and a much anticipated new design...

We’re starting off strong with a huge episode on seamounts! We speak to a friend of the show, Ashley Rowden who’s an expert in all-things benthic and we find out why seamounts are just so cool. We also get a little distracted and reminisce about the ultimate offshore championship: sausage-fest. We get to hear from the scientists on board the RRS Discovery who are currently on an expedition to discover the life that exists on the seamounts surrounding St Helena and the Ascension Islands. A couple of our friends on board also recall their ‘crossing the line’ experience, and how they’re finding working on board a research vessel. We have huge news! You’ll be very excited to hear that we have released a new design for our merch, featuring our favourite parasite - the tongue-eating isopod, Cymothoa exigua!

Our short and to the point PRESSURISED version of episode 8. 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 Working in the deep sea is entirely dependent on technology and the incredible forces push engineering to its limit. If you are doing something that no one has done before, chances are you are going to have to make some of your own tools. Unfortunately, we must spend a lot more on our equipment for the same data as shallower science. This makes funding difficult but also makes the deep sea quite an exclusive club. We are joined by James Cameron (yes, that one) to talk about solving the problems of working deep with new technology. He shares how he went about illuminating the Titanic and confesses that his films are often an outlet for the technology he wishes he could build. Some of the concepts coming in Avatar 2 are an example of this. Don Walsh joins us as ever to give his take on the importance of the engineering that allows us to do the things we do.
