032 - Whale falls with Craig Smith
Friday Feb 03, 2023
Friday Feb 03, 2023
This month is a fun one (maybe not if you love cetaceans) as we’re covering whale falls! That’s right, dead whales and the ecosystems they create on the seafloor. 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!

PRESSURISED: 005 - Storytelling with Susan Casey
Friday Jan 27, 2023
Friday Jan 27, 2023
Our short and to the point PRESSURISED version of episode 5. 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/005-storytelling-with-author-susan-case
In this episode we explore the power of storytelling and complete the arc of our first five episodes: science communication and perception of the deep sea.
We talk with multiple New York Times bestseller Susan Casey about telling a good story and engaging people with a narrative, while still being scientifically accurate. Plus, Don Walsh is kind enough to record his thoughts on the importance of good storytellers.

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!

Friday Jan 06, 2023
Friday Jan 06, 2023
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.
Don shares his own experiences of these impressive habitats (and the not-so-impressive lunches that came alongside them). Plus, we hear from you in the form of listener questions, children’s books and (another?!) deep-sea conspiracy theory. Buckle-up for a big one!

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.

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.

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.

The Professor is back from his adventures at sea with lots of exciting new updates. He talks us through some of his key findings from this already iconic deep-sea expedition. We also get to hear from an often overlooked figure in these expeditions: the ship's captain. Alan and Captain Stuart Buckle have a shared history of seagoing. Travelling the world together onboard the DSSV Pressure Drop during the Five Deeps expedition and during the Professor's recent venture to the Japanese trenches. Captain Stu talks us through his journey into becoming a captain and how he managed to bag the role of captain during James Cameron's legendary Mariana Trench dive.
We also hear from one of our favourite captains and long-time guest of the show, Don Walsh. Don recalls how he sharpened his skills in ship handling and his methods of teaching these skills to the next generation of sailors.
Deep-sea news is a mixture of policy and goo this month. Deep-sea mining tests get the go-ahead, and Alan and Thom try and figure out what a certain spiky blue goo found at the bottom of the sea might be.

Here’s our first ever 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.
Read the show notes and find the full episode here:
https://www.armatusoceanic.com/podcast/deco-stop-001
In our first ever episode, we talk to Kat Bolstad, the leader of the AUT lab for cephalopod ecology and systematics (ALCES) at Auckland University in New Zealand.
We talk about squid Christmas, chasing the colossal squid, Kat’s career journey and her truly incredible record of being the deepest lactating human (we think). She also tells us how she once made a liar out of Sir David Attenborough. We’re 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!

PRESSURISED: 002 – Exploring the Mariana Trench with Don Walsh
Friday Sep 23, 2022
Friday Sep 23, 2022
Our short and to the point PRESSURISED version of episode 2. 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!

https://www.armatusoceanic.com/podcast/002-exploring-the-mariana-trench-guest-don-walsh
In this episode we have an amazing interview with legendary oceanographer, Don Walsh. In 1960, Don and Jacques Piccard were the first people ever to reach the ocean’s deepest point – Challenger Deep in the Mariana Trench in the bathyscaphe Trieste. Since then, Don tends to get asked the same questions about the dive but he is full of other stories at least as interesting. Some include getting a tour of the heavens from his old dive buddy Arthur C. Clark, almost joining the Apollo Program and being involved in the first remote sensing of our oceans from space. He is still passionate about science communication and we discuss how important storytelling is when sharing science.

With the Professor out at sea, Thom goes off the rails and finally gets his answers on cave biology. What are the similarities and differences between the deep-sea and cave ecosystems? How are they linked? Do we know more about the moon than cave biolo…. just kidding! We speak to the legendary Professor Thomas Iliffe, who has shaped the field of biospeleology (cave biology); discovering over 250 species, and 3 new orders (now you don’t hear that every day)! He talks us through the formation of these habitats, what dive surveys are really like, and how to discover the most fascinating of organisms. We also hear from Martin Pollizotto, a listener (and expert cave diver) on bioluminescence in cave systems (or a lack thereof).
We had a lot of deep-sea news this month! New species are being discovered, Alvin is back in the water breaking previous depth records, we have new tech AND some interstellar news!
