"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!

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).
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.

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!

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?

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.

Thom thought he had the podcast to himself, but it turns out the professor is back after 88 days at sea. 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.

The Professor is back on land and Dr Thom is back from Squid Christmas, what a better time to talk about the squishiest of deep sea critters? We talk with George Matsumoto from MBARI all about gelatinous deep sea species. How do we study them? How on earth can we preserve them or even capture their fragile bodies? Plus, we find out exactly what that curious little blue spiky blob was.
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. We want to say a huge thank you to those patrons who have already pledged to support us:

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.
If you’re wondering what jobs are out there in science or just curious to know what goes on behind the scenes at a museum, this episode has some surprises for you.

Alan is somewhere in the middle of the Pacific Ocean and Thom has been dissecting fish left right and centre at Te Papa. What better time to talk about deep-sea digging?
After the exciting news last month about the geological cruise that drilled through the Moho (the area where the Earth’s crust meets the mantle), we thought it would be interesting to talk with Andrew McCaig, the co-chief scientist for that expedition. Andrew talks us through the expedition's goals, achievements and the drilling process itself. Why were geologists interested in reaching this area and what exactly is serpentinisation?

Andrew talks us through the expedition's goals, achievements and the drilling process itself. Why were geologists interested in reaching this area and what exactly is serpentinisation?
We also hear from two other crew members onboard the JOIDES Resolution during the 399 expedition, Igneous petrologist, Kuan Yu Lin and marine technician Luan Heywood. Kuan and Luan talk us through their experiences of working onboard the research vessel and why expedition 399 was so special.
We also hear from previous guest and great friend of the show, Ashley Rowden (his interview on seamounts can be found in episode 30). We grabbed him quickly before he chaired the deep sea session at the New Zealand Marine Science Society conference and he treated us to a great story of James Cameron’s involvement in a previous conference that Ashley was organising.
