Tonga trench special
Friday Sep 13, 2024
Friday Sep 13, 2024
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).
Thanks again for tuning in, we’ll deep-see you next time!

Squidtember with Kat Bolstad
Friday Sep 06, 2024
Friday Sep 06, 2024
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.
Thanks so much for bearing with us whilst we get episode 50 together for you, we can't wait for you to hear it soon!
Thanks again for tuning in, we’ll deep-see you next time!

To finish off our cartilaginous fish mini-series, we’re getting into our personal favourite: the chimera.
These little oddballs are closely related to sharks and rays but often go unmentioned. They are full of intriguing quirks, from lacking a stomach to possessing a reproductive appendage on their head! We speak with Dr Brit Finucci from NIWA, a lover of deep water sharks and champion kicker of heads (she is also a competitive Muay Thai fighter) all about these fascinating fishes and why they are so interesting.

We also speak with Leo Richards from Natural World Facts about his journey into making deep sea documentaries. 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.

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.

PRESSURISED: 023 – Keeping deep-sea animals with The Monterey Bay Aquarium
Friday Jun 28, 2024
Friday Jun 28, 2024
Our short and to the point PRESSURISED version of episode 23. 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/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.

PRESSURISED: 047 - The depths of Lake Baikal with Marianne Moore

Located in southern Siberia and covered in thick ice for almost half of the year, the colossal Lake Baikal reaches depths of 1600m making it the oldest, and deepest lake in the world. With hydrothermal vents, methane seeps and vast swathes of endemic species, this ancient lake was too tempting not to talk about.
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!
We’re really trying to make this project self-sustaining so we have started looking for ways to support the podcast.

The depths of Lake Baikal with Marianne Moore

Located in southern Siberia and covered in thick ice for almost half of the year, the colossal Lake Baikal reaches depths of 1600m making it the oldest, and deepest lake in the world. With hydrothermal vents, methane seeps and vast swathes of endemic species, this ancient lake was too tempting not to talk about.
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. Kakani tells us about how it’s doing in its first month of release, and how it’s already making an impact in training deep sea AI models.

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 find the idea of real people in the actual world wearing this so surreal!

This month we're talking about the flattest of the elasmobranchs: the bottom-dwelling batoids - the deep sea rays and skates!
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).
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.
Thanks again for tuning in, we’ll deep-see you next time!

It wouldn’t be a Coffee with Andrew segment without a memorable insight into the world of a fish curator - and this month’s segment is no different! This time, Dr Thom asks Andrew about an unexpected factoid in one of Andrew’s publications: ‘Yolk smells and tastes like sweetened condensed milk’. We find out exactly how Andrew knows this.

PRESSURISED: 021 - Deep sea images and AI with Kakani Katija
Friday Apr 26, 2024
Friday Apr 26, 2024
Our short and to the point PRESSURISED version of episode 21. 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!

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. We find the idea of real people in the actual world wearing this so surreal!

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?

It’s February, the month of love and there’s love in the deep ocean too. 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? We find the solutions to all these problems and more.
