    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.

    Antarctic Fishes
    Feb 8 2025
    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.

    PRESSURISED: 054 - Going to Antarctica

    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.

    https://www.armatusoceanic.com/podcast/053-corals

    With Dr Thom and The Professor busy prepping for their upcoming expeditions offshore, we had time to squeeze out one more episode before they set sail.

    We caught up with the legendary Di Tracey from NIWA to talk all things deep-water corals. How they live, what makes them different from their shallow water relatives, and how they are adapted to life in the deep dark ocean. Di's long career in deep-sea ecology is also intertwined with her extensive work in making the marine sciences a better place for women to work. She talks us through what it was like to begin her career offshore, often being the only woman on board, and how she helped change the industry for the better.

She talks us through what it was like to begin her career offshore, often being the only woman on board, and how she helped change the industry for the better. In the news this week we have a few exciting new updates. We can indeed confirm that as of our last episode where we spoke about the vulnerability of subsea cables, there were multiple apparent attacks and cables were cut. We can only assume that hostile nations do indeed listen to the deep-sea podcast (thanks for subscribing!). Andrew is back from his stint offshore and he is chock-full of stories for us. Brand new dragonfish species, near-misses with box jellyfish and also some cookie-cutter sharks. It's all happening!

    PRESSURISED: 052 - Blackwater diving
    Nov 8 2024

    Our short and to the point PRESSURISED version of episode 52. 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/052-blackwater-diving

    This month, we come face to face with deep sea species in our blackwater diving special.

    Join us this episode as we jump into the fascinating world of blackwater diving, where expert scuba divers plunge into the open ocean at night in order to catch a glimpse of our favourite deep sea faces. We talk with expert blackwater divers to find out what it’s like to venture into the open ocean at night, when deep sea species rise from the depths to feed. How do they capture such remarkable photographs in such challenging conditions? What are some of their favourite species to encounter? What is it like to see bioluminescence in person and how is this related to science and the discovery of new species? Whether you’re a pro-diver yourself or prefer to stay dry, this episode is jam-packed with interesting stories and insights into this poorly understood environment.

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