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!

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

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.

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.

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.

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. 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.
