A couple of deep-sea scientists talk everything deep sea! Interesting facts, recent news, myth-busting and interviews with the most interesting people we know.
eDNA with Georgia Nester | The Deep Sea Podcast | Episode 59 Welcome to the PRESSURISED version of episode 59, just the science, none of the waffle For this month's interview, we speak with Dr. Georgia Nester, a colleague of Alan's from the University of Western Australia, about eDNA (Environmental DNA is any genetic material left behind by organisms in an environment). She talks about how several collection methods, eg.: Niskin bottles, sponges and paper filters, located on the deep-sea lander system, can retrieve different types of eDNA from the deep. Georgia also touches on how diel migrators can really mess with eDNA data, and larvae gave her a surprise when she kept getting hits from very deep-living fish in her surface samples. Georgia even used a water sample to locate surprise eDNA evidence of the Giant Squid in Australian waters, which Al takes as a chance to remind Thom of his Antarctic colossal squid failure. Alan talks about how valuable he thinks eDNA is, how it can give a great snapshot of what can't be seen on the footage or in the submersible, and how it might be able to narrow down species that are difficult to catch, like Bassozetus cusk eels.

eDNA with Georgia Nester | The Deep Sea Podcast | Episode 59 “Exploration is about the place, adventurism is about the person, science is about the question” Professor Alan Jamieson In an episode recorded earlier than usual, which is to say not recorded late, and so perhaps recorded right on time?... we are talking about environmental DNA or eDNA. Thom is headed off to Norfolk Island, north of New Zealand, to characterize the unique life in the region and hopefully not be eaten by sharks. Alan's been up to secret things, organizing everyone's lives and, for a change, is recording this episode from the same country as the last one. In the news, Thom and Alan discuss a recent paper about the extent of ocean exploration, the valuable research it was based on, and the unfortunately defeatist tone. There is a lot left to do, but we have done so much! Also in the news: Bottom trawling releases not only organic carbon into the ocean but also pyrite, which reacts with oxygen in the water and reduces the oceans' ability to absorb carbon from the air. An art installation pairs a Sri Lankan artist with JAMSTEC and NuStar Technologies for a collection of steel cubes located 7,000 meters (23,000 feet) below the ocean close to the Marianas Trench. The cubes are housed in a seismic monitoring system designed for registering tectonic plate movements. And finally Al and Thom discuss gene mutation in deep-sea fish and a new paper that gives evidence to an old theory that some deep-sea fish are “ancient survivors,” from dinosaur times, while others are “new immigrants,” post mass extinction. For this month's interview, we speak with Dr. Georgia Nester, a colleague of Alan's from the University of Western Australia, about eDNA (Environmental DNA is any genetic material left behind by organisms in an environment). She talks about how several collection methods, eg.: Niskin bottles, sponges and paper filters, located on the deep-sea lander system, can retrieve different types of eDNA from the deep.

Welcome to the PRESSURISED version of episode 58, just the science, none of the waffle We are still talking about Antarctica, the continent that keeps on giving! For this month's interview, we speak with Devin Harrison - Marine Geoscientist/Postdoctoral Researcher at Kelpie Geoscience - Devin is a postdoctoral research fellow at Kelpie Geoscience. His research utilises high-resolution topographic models of the seafloor and complementary geophysical and geospatial datasets to understand the geomorphic evolution and process landform relationship of the deep sea and the continental shelves. Devin is particularly interested in the glacial geomorphological record and the evolution of glacial environments from the last glacial maximum (~20-25 thousand years ago) to the present day. We're really trying to make this project self-sustaining, so we have started looking for ways to support the podcast.

We are still talking about Antarctica, the continent that keeps on giving! Alan and Thom discuss trying to stop working momentarily, constructing a treehouse, and acquiring a shark. In the news, we rattle off a list of newly discovered species with some very cool (but hard to pronounce) names. There has been a lot of squiddy news. Footage of divers swimming with a giant squid has resurfaced; in an exclusive for the podcast, Alan has recorded more amazing Magnapinna (bigfin or elbow squid) footage. And the biggest bit of news: the colossal squid has been seen alive in its natural habitat for the first time! Thom and Kat were part of the press conference. Megalodon (the not-deep-sea and very extinct shark) has been reassessed based on what we do know. It was likely longer and slimmer than we thought, and we have estimations for their speed and size at birth. We also have a new coelacanth population and a classic car found in the deep.

It's the last in our run of episodes about Antarctica. We are all back home, and we promise to stop bothering the poor continent. Thom couldn't talk about it until after the press release, but the Schmidt Ocean Institute cruise he was on had to look at the seabed under a 150-meter-thick ice shelf right as it moved out of the way. We talked to the science leads on that cruise, Patricia Esquete and Sasha Montelli. We learned about the hydrography and glaciology of that region and then the seabed and communities that were revealed when the ice shelf moved away.

It's the last in our run of episodes about Antarctica. We are all back home, and we promise to stop bothering the poor continent. Alan and Thom discuss returning to an inbox of horrors and readjusting to time away. More cable cutting in our news updates, blobfish being voted fish of the year, and the tongue-eating louse potentially being invertebrate of the year. We don't want to say we influence the news, but it seems a little spooky. Thom couldn't talk about it until after the press release, but the Schmidt Ocean Institute cruise he was on had to look at the seabed under a 150-meter-thick ice shelf right as it moved out of the way. We talked to the science leads on that cruise, Patricia Esquete and Sasha Montelli. We learned about the hydrography and glaciology of that region and then the seabed and communities that were revealed when the ice shelf moved away. Kat and Thom updated us on what it was like to join a tourist expedition ship, and we grabbed a Coffee With Andrew to learn what it was like to dive almost 5km deep in a sub.

Coming to you from an Airbnb, above a ski hire shop, next to a construction site in Ushuia, Argentina… It's a very special episode as we continue to pester Antarctica. Alan checks in from Barcelona for mysterious reasons. We'll have to get the truth our of him in the future… Lots is going on in the news; deep-sea fish keep turning up, including a little Melanocetus anglerfish - sometimes called a black seadevil. This has had a real impact on people. The media tried to call it a monster, but the people fell for this little fish. An orfish, the doomsday fish, also turns up, but is that really a sign of doom? There's a new giant isopod, and it's named after Darth Vader - Bathy-normouse! We get excited about Beryllium-10 and ponder neutrinos. But what we are here for today is a very special birthday.

We talk to Antarctic fishes expert Thomas Desvignes about the fishes that are only found there and their amazing adaptations. Of course, we also have a remote coffee with Andrew.

We can indeed confirm that as of our last episode where we spoke about the vulnerability of subsea cables, there were multiple apparent attacks and cables were cut. We can only assume that hostile nations do indeed listen to the deep-sea podcast (thanks for subscribing!). Andrew is back from his stint offshore and he is chock-full of stories for us.

We made it to episode 50 and managed to pin down the professor to tell us all about his adventures offshore in the world's second deepest point: the Tonga trench. Expect to hear all about how the colossal deep-sea expedition is going, including the time Alan piloted a submarine to 2000m, stumbled upon a rarely seen deep-sea squid, and made poor Steve's life difficult (the onboard media guy). Life on land is also just as chaotic as Alan has been jetsetting all over the world, with his shiny new OBE medal safely tucked in his backpack pocket, plus a very mysterious scroll from the king arrived and is now living proudly in his downstairs loo. For those who really love the show, Alan shared with us pictures of all the species he found in the Tonga trench, and this extended video version of the episode is available now via our Patreon (and will be made publicly available on September 20th).

As it turns out, returning to life on land after a mega deep-sea expedition takes a lot of work! So, whilst we aren't quite ready to share with you our Tonga Trench special, here is a mini-episode to keep you busy until we get back to you with episode 50. We're talking all about SQUIDTEMBER with long-time friend of the show, Kat Bolstad from the AUT Squid Squad. Which squid will reign supreme come the end of the month? It's up to you to decide! You can find the links to vote, plus all of the other festivities here on the AUT Twitter page. Thom and Kat also tell us a little about their latest project... attempting to flirt with deep-sea squid. Light-up paddles are involved.

If you have ever searched for deep-sea videos online, then you will have definitely come across Leo's content, as his captivating way of sharing the deep-sea has reached millions of people. Talking about high-quality content, The Professor has been joined offshore by a team of filmmakers, ready to capture the latest in hadal research. So expect some highly professional footage to come out in the next few weeks! Finally, Andrew talks us through some physical features of the Chimera, including its pretty hefty defensive spine and some gnarly stories about things getting impaled.

We're back on the elasmobranch train with our latest episode all about deep-sea sharks! We speak with Justin Cordova, co-founder and deputy director of The Rogue Shark Lab all about the fascinating world of deep-sea sharks! What makes them different from their shallow-water relatives? Why do their eyes glow green? How exactly do you get into a career in deep-sea shark research? The Professor is trapped in paradise (somewhere in Fiji) whilst he quarantines before his next big offshore expedition. But he's not alone - alongside his new pal Roger (the guard gecko) he's quarantining with deep-sea celebrity, Jason 'J-Rod' Rodriguez. The famed SuBastian ROV pilot is joining Alan on this next leg of the expedition to the Tonga Trench. Make sure you're following us to hear all of the updates in our next episode! Andrew is back from his travels and was just as excited about our Lake Baikal episode as us! In this month's Coffee with Andrew segment, he talks us through the unbelievable similarities between deep-ocean and the deep-lake fish of Baikal.

Read the show notes and find the full episode here: https://www.armatusoceanic.com/podcast/023-deep-aquaria 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.

We speak with Professor Marianne Moore, a Limnologist who has been working on the lake for over 2 decades. She guides us through its incredible ecosystems and species such as the world's only freshwater seal, deep water insects and foot-long flatworms! Plus, we hear about the myths and mysteries of the lake: from scientifically testing whether the mafia can use amphipods to effectively dispose of bodies, to whether there really is 1600 tonnes of gold hiding at the bottom of the lake. The Professor is back on land after a succession of crazy adventures which includes writing a paper on backwards swimming in deep sea fish, finding the worlds deepest nudibranch (possibly) plus discovering his friends live in the most metal place ever. There's no Coffee with Andrew segment this month as he is taking a well deserved break (and is possibly touring the country looking for the strangest milks he can find), but we do hear from Kakani Kajita about the recent release of FathomVerse - the mobile game helping to contribute to deep sea citizen science.

Read the show notes and find the full episode here: https://www.armatusoceanic.com/podcast/022-dive-streaming One of the most exciting parts of our job is going to places that no one has ever been before and seeing things that no one has ever seen. It turns out, we were making that far harder than it needs to be, we can do all this from home! Several of the big names in deep-sea exploration live-stream (or dive-stream if we're being cute). With just a few seconds delay, you can see deep-sea exploration as it happens and may be present for very significant finds. You never know what you're going to find down there. The big players in this space are the Schmidt Ocean Institute, Nautilus Live from the Ocean Exploration Trust and Ocean Exploration/Okeanos Explorer from NOAA. We are lucky enough to chat with Kasey Cantwell, the Operations Chief of the NOAA Ocean Exploration Expeditions and Exploration Division. We talk about the amazing opportunities this new way of doing science presents. From allowing 300 experts to take part, to swapping out your expert team when you find something unexpected and even the physical and societal barriers that can be removed. But it's not just about getting science done, it's about sharing these experiences with everyone. Online communities are forming around these streams and illustrations, poetry and memes are just as valid outputs. Check out our podcast merch! Please do send in any pics of you wearing the merch.

We're kicking off our cartilaginous fishes (Chondrichthyes) mini-series with the batoids - the rays and skates! Sharks are often associated with the deep sea, but did you know that batoids have been observed as deep as 3000m? We speak with Will White who researches elasmobranchs across the world and who has described 50 species! He talks us through the differences between sharks rays and skates, and how these species utilise the deep sea. We hear about their fascinating (and hugely varied) reproductive strategies like those that are viviparous (will keep the eggs in their uterus) and others that are oviparous (will lay the eggs).

Read the show notes and find the full episode here: https://www.armatusoceanic.com/podcast/021-ai We have often talked about how difficult it is the get data from the deep sea… but would you believe that the bottleneck to our understanding of the deep ocean, at least as far as visual data, is processing those images? Turning a picture of the deep sea into a list of species, habitat type, sediment type etc. is a time-consuming process that requires a wide range of skilled people. Due to time/funding constrains a lot of valuable information is lost. A team looking at a specific question will have lots of information in their data that other teams could use. A picture is worth a thousand data points. We chat with Dr Kakani Katija, the co-founder of FathomNet, an open-source repository for labelled deep-sea imaging data. The platform is still in beta but it is hoped that it will allow scientists to easily and usefully share their amassed data in a single and easily searchable place. But what about that processing bottleneck? The tech-savvy listener may have noticed that a massive collection of labelled image data is exactly the sort of thing you need to train a Machine Learning or Deep Learning algorithm. Can we automate a lot of the time-consuming image processing and let the experts focus on the new and unusual stuff? It's at this cutting edge that things get exciting and we may be at the cusp of a marine science renaissance. We also launch our podcast merch! Please do send in any pics of you wearing the merch.

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.

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? Plus, we have another instalment of the fan-favourite: Coffee with Andrew. This time, Andrew talks us through his love of hagfish, how to successfully remove their slime, and why brushing their teeth is super important!

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?

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.

"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.

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.

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!

Our short and to the point PRESSURISED version of episode 15. 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: 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! These are exciting times.

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? DID YOU KNOW WE SELL MERCH? Check it out here!! And please do send in any pics of you wearing the merch!

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.

Read the show notes and find the full episode here: www.armatusoceanic.com/podcast/039-molluscs Our very special guest this month is the fantatsic Kerry Walton from the Te Papa Museum in New Zealand. 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 (?!?!).
