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!

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.

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.

Read the show notes and find the full episode here: https://www.armatusoceanic.com/podcast/019-squid As promised in the Christmas special, we call the ‘squid-phone’ – a special line used by scientists globally when they seem something strange and squiddy. 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.

Read the show notes and find the full episode here: https://www.armatusoceanic.com/podcast/041-whales We all know that Thom and Alan aren’t the biggest fans of ‘air-breathers’ aka. marine mammals like dolphins and whales, but there are a few species that are allowed into the deep-sea club. We hear from Dr Nicola Quick who researches the incredibly elusive beaked whales, a group that likely spends the majority of their time in the deep sea. 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).

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. What’s more, the Professor tells the story about the infamous Goblet of Hades. If you manage to see this little piece of history in the background of documentaries, please do send a pic in!

Read the show notes and find the full episode here: www.armatusoceanic.com/podcast/015-space-pt2 We are still exploring the parallels between space and deep-ocean exploration. 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. Is it a nudibranch? Or is it something else entirely? We’re really trying to make this project self-sustaining so we have started looking for ways to support the podcast.

Read the show notes and find the full episode here: www.armatusoceanic.com/podcast/014-space-pt1 The topic for this double episode is, as ever, the deep sea. 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.

Kerry talks us through the weird and wonderful world of marine molluscs, from the deep to the not so deep, and what makes them fascinating to study. We learn about the very interesting Chainmail snail (Chrysomallon squamiferum), or as some call it ‘the scaly-foot snail’ (but we all agree that ‘chainmail snail’ is way cooler). Plus we hear all about the unbelievable species of limpets that survive on baleen from whalefalls, and those that live on human hair in estuaries (?!?!).
