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.

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.

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 have lots of exciting upcoming episodes all about the (in)famous hagfish, deep sea sharks and our favourite: chimera. Stay tuned!

Glossary
Cold-water corals - Deep-water corals (or cold-water corals) grow in water temperatures of 4 - 12°C. Unlike shallow water corals, they do not depend on a symbiotic algae (zooxanthellae) for growth and survival, resulting in slower growth.
Deep-sea mining - The process of extracting manganese nodules from the deep ocean floor.
Hagfish - An eel-shaped jawless fish. Hagfish are marine predators and scavengers.
Hull - A hull is the watertight body of a ship.
Megalodon - An extinct species of giant shark that lived approximately 23 to 3.6 million years ago.
Metagenomes - Genetic material taken from the environment rather than from one individual.
OBE - (Order of the British Empire) is a British award rewarding contributions to the arts and sciences, work with charitable and welfare organisations, and public service outside the civil service.
Squalene - Squalene is a natural oil that comes from shark liver.
Submarine - A submarine (or sub) is a watercraft capable of independent operation underwater.
Thrusters - Manoeuvering thrusters (bow thrusters and stern thrusters) are propulsion devices built into, or mounted to, either the bow or stern, of a ship to make it more manoeuvrable.

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. 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.

We love going to sea, it is probably the best part of the job. 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? How can you get a celebratory tattoo offshore from an unqualified scientist? “Don’t worry, he’s a doctor, not that sort of doctor but don’t worry about that!”

"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.
Thanks again for tuning in, we’ll deep-see you next time!

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.

Glossary
Benthopelagic - Living and feeding near the bottom as well as in midwaters or near the surface but also the depth zone about 100 metres off the bottom at all depths below the edge of the continental shelf.
Endothermy – Animals that regulate their body temperature (we used to call this ‘warm blooded’)
Geomagnetic – The Earth’s magnetic field e.g., magnetic north.
Mantle – The muscular tube that makes up a squids body.
Mesopelagic – Open water fish between about 200 and 1,000 metres (approximately 650 and 3,300 ft) down.
SoFAR channel - sound fixing and ranging channel. The SOFAR channel acts as a waveguide for sound, and low frequency sound waves within the channel may travel thousands of miles before dissipating.
Vertical migration – Every night, mesopelagic fish come shallower to feed. This is the largest migration on Earth and it happens every day.

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).

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.

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.
Thanks again for tuning in, we’ll deep-see you next time!

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.

GLOSSARY
Canyon - Narrow steep-sided valleys that cut into continental slopes and continental rises of the oceans.
Cleft - A divide.
Continental shelf - A continental shelf is the edge of a continent that lies under the ocean. It extends from the coastline of a continent to a drop-off point called the shelf break.
Holothurian - A sea cucumber. They feed by ingesting sediment to obtain the nutrients.
Lander - A piece of deep sea equipment which free-falls to the seafloor and collects data via cameras, collection equipment etc.
ROV - Remotely operated vehicle. These are robots, tethered to the surface vessel which are used to explore an area in the deep sea, whilst being operated from the surface.

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.

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 (?!?!).

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.

Friend of the show, Susan Casey has also just released her new book The Underworld in which Dr Thom and the Professor make an appearance! 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 so great to see this book finally out there after years of hard work. Get yourself a copy here. Want to hear Susan’s episode of the podcast? Check it out here.
