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!

Our short and to-the-point PRESSURISED version of episode 33. 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!
What if your deep-sea habitat was less rocky and more fleshy? That’s right, the time has come to talk all about deep-sea parasites and their fascinating life cycles.
We couldn’t think of anyone better to speak with than Dr Rod Bray, a pioneer in deep-sea parasitology research. Rod talks us through the captivating world of parasitic worms and his ongoing research into their ecology.

What if your deep-sea habitat was less rocky and more fleshy? That’s right, the time has come to talk all about deep-sea parasites and their fascinating life cycles.
We couldn’t think of anyone better to speak with than Dr Rod Bray, a pioneer in deep-sea parasitology research. Rod talks us through the captivating world of parasitic worms and his ongoing research into their ecology.
Continuing with the parasitic theme, Thom and Alan share their critiques (and also their love for) ‘The Last of Us’, an apocalyptic TV show involving fungal parasitology. The news is somewhat less parasite-y this month with Alan officially extending the depth records for several taxa and there’s a new species of cavefish described! Don also provides a highly unexpected story from his days as Captain of a submarine...
Are you now suddenly parasite-obsessed?! Satisfy your cravings with your very own parasitic deep-sea podcast merch featuring our favourite parasite - the tongue-eating isopod, Cymothoa exigua!

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)! This newfound success has pushed us to release another Deco-Stop episode on neurodiversity in science, coming to you next month!

We’re continuing on our iconic deep-sea habitat trilogy with the episode you’ve all been waiting for… HYDROTHERMAL VENTS!
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 tubeworm trope.
Don shares his own experiences of these impressive habitats (and the not-so-impressive lunches that came alongside them). Buckle-up for a big one!

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.

We’ve been off-piste for a while now so we thought we’d jump straight back into the deep sea with a series of episodes on deep-sea habitats. 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! A perfect gift this holiday season for the whole family.

Our short and to the point PRESSURISED version of episode 30. 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/030-seamounts
We’ve been off-piste for a while now so we thought we’d jump straight back into the deep sea with a series of episodes on deep-sea habitats. 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 get to hear from Don as he recalls his experiences of "crossing the line", a tradition deep-rooted in the maritime industry.
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! A perfect gift this holiday season for the whole family. Check out our podcast merch here! Which now includes Alan’s beloved apron.

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.

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! A perfect gift this holiday season for the whole family.

We turn the spotlight on ourselves and wonder why humanity seems to have an intrinsic fear of the deep sea. Glenn Singleman joins us to give a psychological explanation for why we feel differently about the deep sea and we take a deep dive into deep-sea tropes we see in the media.

Everyone has been very busy this month with Thom and the Professor officially describing a new species of blue snailfish, alongside their adventures in Singapore. We hear from one of our old students about the work he’s been doing in deep freshwater ecosystems, which got us thinking about these unique environments and the kind of species that live there. We decided to throw one last curveball away from the deep sea and speak with Dr Melanie Stiassny, an ichthyologist who’s focused her research on the deep water fish of the Congo river.
We couldn’t go an episode without discussing the latest deep-sea related conspiracy theories. And of course, we hear from Don about how freshwater affects sub manoeuvres.
