• PRESSURISED: 062 – Mythbusting Ai with Tyler Greenfield

  Welcome to the PRESSURISED version of episode 62, just the science, none of the waffle PRESSURISED: Mythbusting Ai with Tyler Greenfield | The Deep-Sea Podcast | Episode 62 Check out our lovely new website where you can find more detailed notes, images and links to the wider reading. 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. He was even a credited consultant on the new (2025) Walking with Dinosaurs.   Support the show The podcast is self-sustaining (just) thanks to our lovely listeners.

• PRESSURISED: 061 – Trench nutrient cycling with Ronnie N. Glud

  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!   Support the show The podcast is self-sustaining (just) thanks to our lovely listeners.

• Trench nutrient cycling with Ronnie N. Glud

  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.
