• PRESSURISED: 056 - Colossal squid

  Coming to you from an Airbnb, above a ski hire shop, next to a construction site in Ushuia, Argentina… It’s a very special episode as we continue to pester Antarctica. We are here for today is a very special birthday. Our favorite and most elusive colossal squid, Mesonychoteuthis hamiltoni, has been described for 100 years but never seen in its natural environment! We are having a birthday bash for the big girl. Joined by Kat Bolstad of the Auckland University of Technology, Squid Squad, we learn what we do and don’t know, as well as the project Thom and Kat came up with to try to find it.   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: Luz, Caro Mclaren, Tadhg, Austin Horenkamp, Thora, Lindsey and Harrison   Thanks again for tuning in; we’ll deep-see you next time!   Check out our podcast merch here! Which now includes Alan’s beloved apron and a much anticipated new design...    Feel free to get in touch with us with questions or your own tales from the high seas on: [email protected] We’d love to actually play your voice so feel free to record a short audio note!   We are also on  Twitter: @DeepSeaPod Facebook: DeepSeaPodcast Instagram: @deepsea_podcast Keep up with the team on social media Twitter:  Alan - @Hadalbloke Thom - @ThomLinley  Instagram:  Thom - @thom.linley  BlueSky: Thom - @deepseapod.com   Follow Kat on  Bluesky: @autsquidsquad.bsky.social Twitter: @ALCESonline Reference list Interview Original colossal squid description Pure Ocean Fund Intrepid Travel Auckland Aquarium - SEA LIFE Kelly Tarlton's Aquarium Us testing the camera in the aquarium Mantis Sub underwater housings https://www.mantis-sub.com/ Otago University and the NZ Whale and Dolphin Trust Importance in sperm whale diet Colossal and giant squid eyes Toothfish predation by colossal squid one and two Whales vs squid arms race Ceph Ref and GoFundMe Glossery Umwelt - the sensory world an animal lives in.

• Colossal squid birthday special

  Coming to you from an Airbnb, above a ski hire shop, next to a construction site in Ushuia, Argentina… It’s a very special episode as we continue to pester Antarctica. Alan checks in from Barcelona for mysterious reasons. We’ll have to get the truth our of him in the future…   Lots is going on in the news; deep-sea fish keep turning up, including a little Melanocetus anglerfish - sometimes called a black seadevil. This has had a real impact on people. The media tried to call it a monster, but the people fell for this little fish. An orfish, the doomsday fish, also turns up, but is that really a sign of doom? There’s a new giant isopod, and it’s named after Darth Vader - Bathy-normouse! We get excited about Beryllium-10 and ponder neutrinos.  But what we are here for today is a very special birthday. Our favorite and most elusive colossal squid, Mesonychoteuthis hamiltoni, has been described for 100 years but never seen in its natural environment! We are having a birthday bash for the big girl. Joined by Kat Bolstad of the Auckland University of Technology, Squid Squad, we learn what we do and don’t know, as well as the project Thom and Kat came up with to try to find it.   We’re really trying to make this project self-sustaining, so we have started looking for ways to support the podcast.

• PRESSURISED: 055 - Antarctic Fishes

  Our short and to the point PRESSURISED version of episode 55. 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: https://www.armatusoceanic.com/podcast/055-antarcticfishes   Now it’s Thom’s turn to hit Antarctica. He’s out with the Schmidt Ocean Institute on the Antarctic Climate Connections expedition to the Bellinghousen Sea, to the west of the Antarctic Peninsula.  He will record, edit and upload a podcast from there… somehow. This episode may sound a little rougher as a result, but the content is gold as ever… Underrated belter alert.   We talk to Antarctic fishes expert Thomas Desvignes about the fishes that are only found there and their amazing adaptations. Of course, we also have a remote coffee with Andrew.   We’re really trying to make this project self-sustaining so we have started looking for ways to support the podcast.

• Antarctic Fishes

  The gang has swapped places, Alan is back in Perth and now it’s Thom’s turn to hit Antarctica. He’s out with the Schmidt Ocean Institute on the Antarctic Climate Connections expedition to the Bellinghousen Sea, to the west of the Antarctic Peninsula.  He will record, edit and upload a podcast from there… somehow. This episode may sound a little rougher as a result, but the content is gold as ever… Underrated belter alert.   The Prof managed to have some downtime with the family in Antarctica and has some great stories to tell, he’s a chopper guy now. He’s over subs and only into helicopters now… the subs of the sky.    We talk to Antarctic fishes expert Thomas Desvignes about the fishes that are only found there and their amazing adaptations. Of course, we also have a remote coffee with Andrew.   We’re really trying to make this project self-sustaining so we have started looking for ways to support the podcast.

• PRESSURISED: 054 - Going to Antarctica

  Our short and to the point PRESSURISED version of episode 54. 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: https://www.armatusoceanic.com/podcast/054-antarctica   It’s a big one! With The Professor down in Antarctica and Dr Thom not too far behind him, we’ve got an update live from the field. We’re talking about Antarctic submarine dives, below-freezing trenches, unexpected uses of glacial ice and, of course, the importance of growing a beard… But they’re not alone! This month we’re joined by the incredible Shaylyn Potter (Marine Scientist, Sub Pilot and polar diver) as she talks us through the intricacies and unique nature of this environment. We learn about what makes an iceberg different from a bergy bit (yes, that’s a real word), and why plans don’t always go as planned in the south.   We’re really trying to make this project self-sustaining so we have started looking for ways to support the podcast.
