    We’re back on the elasmobranch train with our latest episode all about deep-sea sharks!

    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.

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

  • PRESSURISED: 023 – Keeping deep-sea animals with The Monterey Bay Aquarium
    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.

  • The depths of Lake Baikal with Marianne Moore
    Jun 7 2024
    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.

  • PRESSURISED: 022 - Live-streaming the deep with Kasey Cantwell
    May 24 2024

    Our short and to the point PRESSURISED version of episode 22. 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!

    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.
