    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!

    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. Also in the news, get ready for updates on: A new story map on mesophotic reefs following the Deepwater Horizon spill in the Gulf of Mexico.An exciting project charting shipwrecks in the Great Lakes using cutting-edge ROV technology for 3D modelling.The discovery of a deep-sea limpet named after a One Piece character, found at an astonishing 6 kilometres deep!How Earth's deep-sea microbes are being used to model potential life on Jupiter's moon Europa.Groundbreaking research on a new bioplastic that vanishes by over 80% in extreme deep-sea conditions, offering hope for sustainable solutions. 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.

    Jul 17 2025
    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.

    PRESSURISED: 059 - eDNA with Georgia Nester
    Jun 15 2025
    eDNA with Georgia Nester | The Deep Sea Podcast | Episode 59 Welcome to the PRESSURISED version of episode 59, just the science, none of the waffle

    For this month’s interview, we speak with Dr. Georgia Nester, a colleague of Alan’s from the University of Western Australia, about eDNA (Environmental DNA is any genetic material left behind by organisms in an environment). She talks about how several collection methods, eg.: Niskin bottles, sponges and paper filters, located on the deep-sea lander system, can retrieve different types of eDNA from the deep. Georgia also touches on how diel migrators can really mess with eDNA data, and larvae gave her a surprise when she kept getting hits from very deep-living fish in her surface samples. Georgia even used a water sample to locate surprise eDNA evidence of the Giant Squid in Australian waters, which Al takes as a chance to remind Thom of his Antarctic colossal squid failure.

    Alan talks about how valuable he thinks eDNA is, how it can give a great snapshot of what can’t be seen on the footage or in the submersible, and how it might be able to narrow down species that are difficult to catch, like Bassozetus cusk eels.

    Jun 6 2025
    eDNA with Georgia Nester | The Deep Sea Podcast | Episode 59 “Exploration is about the place, adventurism is about the person, science is about the question” Professor Alan Jamieson In an episode recorded earlier than usual, which is to say not recorded late, and so perhaps recorded right on time?... we are talking about environmental DNA or eDNA. Thom is headed off to Norfolk Island, north of New Zealand, to characterize the unique life in the region and hopefully not be eaten by sharks. Alan’s been up to secret things, organizing everyone’s lives and, for a change, is recording this episode from the same country as the last one. In the news, Thom and Alan discuss a recent paper about the extent of ocean exploration, the valuable research it was based on, and the unfortunately defeatist tone. There is a lot left to do, but we have done so much! Also in the news: Bottom trawling releases not only organic carbon into the ocean but also pyrite, which reacts with oxygen in the water and reduces the oceans’ ability to absorb carbon from the air. An art installation pairs a Sri Lankan artist with JAMSTEC and NuStar Technologies for a collection of steel cubes located 7,000 meters (23,000 feet) below the ocean close to the Marianas Trench. The cubes are housed in a seismic monitoring system designed for registering tectonic plate movements. And finally Al and Thom discuss gene mutation in deep-sea fish and a new paper that gives evidence to an old theory that some deep-sea fish are “ancient survivors,” from dinosaur times, while others are “new immigrants,” post mass extinction.

    PRESSURISED: 058 - Antarctic ice-seabed interactions
    May 9 2025
    Welcome to the PRESSURISED version of episode 58, just the science, none of the waffle

    We are still talking about Antarctica, the continent that keeps on giving!

    For this month's interview, we speak with Devin Harrison - Marine Geoscientist/Postdoctoral Researcher at Kelpie Geoscience - Devin is a postdoctoral research fellow at Kelpie Geoscience. His research utilises high-resolution topographic models of the seafloor and complementary geophysical and geospatial datasets to understand the geomorphic evolution and process landform relationship of the deep sea and the continental shelves. Devin is particularly interested in the glacial geomorphological record and the evolution of glacial environments from the last glacial maximum (~20-25 thousand years ago) to the present day.

    Antarctic ice-seabed interactions
    May 3 2025
    We are still talking about Antarctica, the continent that keeps on giving! Alan and Thom discuss trying to stop working momentarily, constructing a treehouse, and acquiring a shark. In the news, we rattle off a list of newly discovered species with some very cool (but hard to pronounce) names. There has been a lot of squiddy news. Footage of divers swimming with a giant squid has resurfaced; in an exclusive for the podcast, Alan has recorded more amazing Magnapinna (bigfin or elbow squid) footage. And the biggest bit of news: the colossal squid has been seen alive in its natural habitat for the first time! Thom and Kat were part of the press conference. Megalodon (the not-deep-sea and very extinct shark) has been reassessed based on what we do know. It was likely longer and slimmer than we thought, and we have estimations for their speed and size at birth. We also have a new coelacanth population and a classic car found in the deep.
