  • PRESSURISED: 063 – Bioluminescent Symbiosis with Margaret McFall-Ngai
    Nov 15 2025
    Welcome to the PRESSURISED version of episode 63, just the science, none of the waffle

    PRESSURISED: Bioluminescent Symbiosis with Margaret McFall-Ngai | The Deep-Sea Podcast | Episode 63

    Our guest this month is Dr. Margaret McFall-Ngai, an animal physiologist and biochemist who is a staff researcher at Carnegie Institution for Science’s Division of Biosphere Sciences and Engineering, with her lab stationed at the California Institute of Technology in Biology and Biological Engineering. Dr. McFal-Ngai talks us through her work on the stable beneficial relationship between the Hawaiian bobtail squid (Euprymna scolopes) and its partner, the luminous bacterium Vibrio fischeri. Although technically not a deep-sea species, this relationship and its details might help us understand how deep-sea life creates bioluminescence and the possible life cycle impacts for the creatures involved.

  • Bioluminescent Symbiosis with Margaret McFall-Ngai
    Nov 7 2025
    Episode Summary In our newest episode, Bioluminescent Symbiosis, we speak with Dr. Margaret McFall-Ngai, an animal physiologist and biochemist about her work with the Hawaiian bobtail squid (Euprymna scolopes) and its partner, the luminous bacterium Vibrio fischeri. McFall-Ngai provides a great synopsis of how this stable beneficial relationship not only creates light, and supports the bobtail maturation, but can also help us understand what could be going on in the light organs of deep-sea animals. Check out our lovely new website where you can find more detailed notes, images and links to the wider reading. In this episode… Welcome back to the Deep-Sea Podcast, your punk take on all things deep sea! The Professor is jetsetting as always, back in Edinburgh after a stint getting all the equipment ready in the Canary Island and is now happily being confused with professional racecar drivers. He will be back in Perth shortly to celebrate the Deep-Sea center paper publishing streak and reconnect with his Capybara spirit animal. Thom is being called out in New Zealand Parliament, for all the right reasons, and he spent some Deep-Sea conference time in China, avoiding typhoons and pondering science ideas. We are also celebrating 300,000 podcast downloads of the podcast, and appreciate our fans immensely!

  • The Deco-Stop: 004 - No Word for Ocean with Yakup Niyazi
    Oct 3 2025

    Here’s our fourth 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. We have gazed into the abyss, and now it's gazing back at us.

    Alan and Thom speak with Yakup Niyazi, a marine geoscientist who first saw the ocean at the age of 27. This fourth instalment in the Deco-Stop series, which focuses on the human element of deep-sea research, is an inspiring episode about one man’s journey from the desert to the bottom of the ocean, his challenges, achievements, and the deep community support he received along the way.

    Check out our lovely new website, where you can find more detailed notes, images and links to the wider reading.

    In this episode…

    Welcome back to the Deep-Sea Podcast, this month we have a heartwarming Deco Stop episode and are again exploring …‘the human element in deep sea stories..’ - Alan

    In our fourth instalment of the Deco-Stop series, Alan and Thom speak with Yakup Niyazi about his journey from the edge of the Asian Desert to the bottom of the ocean. An ethnic Uyghur who grew up in the city of Aksu, at the edge of the Taklamakan Desert in Central Asia, Yakup grew up not only physically but also emotionally and culturally removed from the sea. Yakup's early experiences pose some interesting questions: What is it like to grow up in a culture that doesn’t really have a concept of the ocean, and few descriptive words for the ocean? How do you interact with the ocean if your only experiences are from movies and television?

    His incredible story is filled with overcoming adversity, fulfilled dreams, landscapes (and seascapes) that come full circle, and a deeper appreciation of the ocean than most people will ever experience. Despite humble beginnings, Yakup has an impressive roster of achievements and a social circle of supportive connections who only want to see him succeed further.

    This inspiring episode reminds us that, regardless of our original circumstances, the world is a vast place filled with incredible opportunities. One day, you might find yourself exiting a hadal submarine, surrounded by the heartwarming cheers of friends and colleagues, having successfully visited the bottom of the ocean you only saw for the first time at age 27.

    “I was a camel before, from the desert, but now I am a shark swimming in the ocean”- Yakup Niyazi

In a follow-up to one of our favourite episodes, Ep 10 Here be Monsters, we bring Tyler Greenfield back for another fascinating chat, this time about Mythbusting in the age of Artificial Intelligence. Our feeds have been filled with images of mermaids, bizarre creatures supposedly from the depths and even strange barnacle washing videos, so we ask Tyler to bring his expertise to weigh in on the prevalence and problems with AI images. Guest Interview Tyler Greenfield is a paleontologist and cryptozoologist whose blog, Incertae Sedis reveals the truth behind some cryptozoological stories and paleontological mistakes. Since his appearance on episode 10, Tyler has finished his bachelor’s, written a good few papers, appeared on other podcasts (none as good as his debut of course) and is almost done with his masters and is about to start his PhD.

  • PRESSURISED: 061 – Trench nutrient cycling with Ronnie N. Glud
    Aug 16 2025
    Welcome to the PRESSURISED version of episode 61, just the science, none of the waffle PRESSURISED: Trench nutrient cycling with Ronnie N. Glud | The Deep Sea Podcast | Episode 61

    Guest Interview: Nutrient cycling in the hadal trenches (6 to 11 km) and the crucial role they play in global element cycling. Professor Ronnie N. Glud, a leading biochemist and Director of the Danish Centre for Hadal Research (HADAL) talks us through how the trenches, once thought to be barren, are actually "dynamic deep-sea hotspots with intensified microbial activity and diversity". Learn about:

    • How hadal trenches act as "depocenters" for organic material, leading to microbial activity that's 2 to 6 times higher than in adjacent abyssal sites.
    • The surprising diversity of microbial "generalists" that easily adapt to the immense pressure and low temperatures, aided by viruses that facilitate "horizontal gene transfer".
    • The return of full anaerobic diagenetic processes (like sulphate reduction and anammox) in trench sediments, making them significant sinks for fixed nitrogen.
    • The role of marine snow and seismic activity in efficiently transporting organic matter and, surprisingly, pollutants like PCBs and heavy metals to these remote depths.
    • Why these trenches are not isolated environments but are highly connected to surface ocean processes, even responding to climate-driven changes in primary production.

    We also have a surprise blobfish guest!

    Aug 3 2025
    In this episode… Welcome back to the Deep-Sea Podcast, your punk take on all things deep sea! Join Dr. Thom Linley and Professor Alan Jamieson as they dive into the latest from the abyssal plain and beyond. Deep Sea News Highlights: We kick things off with a rethinking of the deep-sea boundary! Professor Alan Jamieson discusses his recent "food for thought" paper that challenges the long-held 200-meter definition, arguing for a more scientifically relevant boundary of 1,000 meters. Find out why this seemingly arbitrary line might be doing "a lot of damage" to our understanding and attitude towards the deep sea.

    Welcome to the PRESSURISED version of episode 60, just the science, none of the waffle PRESSURISED: Mesophotic Reefs with Yi-Kai Tea | The Deep Sea Podcast | Episode 60

    In this month's episode, we discuss mesophotic reefs, the deeper extents of coral reefs that have been overlooked in the past. It’s a wild ride that leads us to homemade hyperbaric chambers, the aquarium trade and the world’s most expensive fish. Strap in for a rollercoaster ride as we dive to the limits of scuba.
