63 Degrees North

Nobelmen and women, in fancy clothing and pearls – but with dragon wings and tails. A laughing man with a full head of curly hair. Lions biting the ears off a man whose mouth is full of writhing serpents. These may sound like a weird combination of a gothic novel and a nightmare, but they're something completely different – a description of some of the eerie and surprising sculptures in Nidaros Cathedral, the northernmost gothic cathedral in the world that's located in NTNU's hometown of Trondheim.But what were the messages that stonemasons and religious leaders were trying to send visitors to the cathedral – and how do we interpret these messages 800 years later?My guests on today's show are Øystein Ekroll, chief archaeologist and researcher at the Nidaros Cathedral Restoration Workshop and Margrete Syrstad Andås, an art historian and associate professor at NTNU's Department of Art and Media Studies.You can read more about the history of the cathedral in this article from Norwegian SciTech News: Thousand-year-old cathedral surrenders its secrets, stone by stoneØystein Ekroll has an article about the building history of the cathedral from 1030 to 1537 that you can find here.Øystein's PhD dissertation is available here: The Octagonal Shrine Chapel of St Olav at Nidaros CathedralØystein and Margrete have also edited a book about the cathedral:Andås, Margrete Syrstad, Øystein Ekroll Andreas Haug and Nils Holger Petersen, eds,The Medieval Cathedral of Trondheim: Architectural and Ritual Constructions in their European Context (Traditions and Transformations 3), Turnhout, Brepols, 2007Andås, Margrete Syrstad. “Art and Ritual in the Liminal Zone.” In he Medieval cathedral of Trondheim : architectural and ritual constructions in their European context.

This episode was originally aired on March 16, 2021. Norway doesn't seem like a natural place for the aluminium industry to blossom. But somehow, it did – due in part to the unlikely combination of WWII Germany, a modest English engineer who created a worker’s paradise, an ambitious industrialist prosecuted as a traitor and a hardworking PhD. All of these factors and personalities helped build modern Norway, one aluminium ingot at a time.Today's guests are Hans Otto Frøland, Svein Richard Brandtzæg and Randi Holmestad. Frøland is one of the researchers working in the Fate of Nations project, which is based at NTNU and focused on the global history and political economy of natural resources.

This episode originally aired on Feb. 16, 2022.Trondheim, Norway’s first religious and national capital, has a rich history that has been revealed over decades of archaeological excavations. One question archaeologists are working on right now has a lot of relevance in a pandemic: Can insight into the health conditions of the past shed light on pandemics in our own time? Now, with the help of old bones and dental plaque, researchers are learning about how diseases evolved in medieval populations, and what society did to stem them — and how that might help us in the future.Our guests for this episode were Axel Christophersen, a professor of historical archaeology at the NTNU University Museum; Tom Gilbert, a professor at the NTNU University Museum and head of the Center for Evolutionarly Hologenomics based at the University of Copenhagen; and Elisabeth Forrestad Swensen, a PhD candidate at the NTNU University Museum.You can read more about the MedHeal research project on the project’s home page.Here are some of the academic articles on medieval Trondheim related to the podcast: Zhou Z, Lundstrøm I, Tran-Dien A, Duchêne S, Alikhan NF, Sergeant MJ, Langridge G, Fotakis AK, Nair S, Stenøien HK, Hamre SS, Casjens S, Christophersen A, Quince C, Thomson NR, Weill FX, Ho SYW, Gilbert MTP, Achtman M. Pan-genome Analysis of Ancient and Modern Salmonella enterica Demonstrates Genomic Stability of the Invasive Para C Lineage for Millennia.

This episode originally aired on January 27, 2021.Krill eyeballs. The werewolf effect. Diel vertical migration. Arctic marine biologists really talk about these things. There’s a reason for that — when it comes to the polar night, when humans see only velvety darkness, krill eyeballs see things a little differently. And when the sun has been gone for months, during the darkest periods of the polar night, the moon does unexpected things to marine organisms. Learn more about what biologists are figuring out about the workings of the polar night — and what it means at a time when the Arctic is warming at a breakneck pace. Our guests for this episode were Jørgen Berge, Geir Johnsen, Laura Hobbs and Jonathan H. Cohen. You can see a transcript of the episode here. Fridtjof Nansen’s book about his Arctic expedition is called Farthest North. You can also read about the other influences his pioneering journey had on science here. You can also read about Geir Johnsen’s different research projects in a series of articles from Norwegian SciTech News. The findings of the polar night team are so surprising that they actually wrote a textbook about it, edited by Jørgen Berge, Geir Johnsen and Jonathan H. Cohen. The book is titled Polar Night Marine Ecology: Life and Light in the Dead of Night.Here are some of the polar night research articles:Berge, J., Renaud, P. E., Darnis, G. et al.

It's 1968 and a Soviet sub carrying nuclear warheads has gone missing – lost, with all hands. The Soviets never found it – but the Americans did – in nearly 5000 meters of water.What follows is the strange tale of Project Azorian, an ultra-secret mission by the US Central Intelligence Agency, the CIA, that played on national fervor over deep sea mining to create an elaborate cover story to raise the sub. This strange tale involved Howard Hughes, a journey around the tip of South America, the 1973 Chilean coup and a 1974 burglary. This last resulted in an expose of what has been called one of the greatest covert operations in the CIA's history.I stumbled onto this story in the course of reporting the episode on Norway's decision to open its seabed to exploration and mining, and couldn't resist making a little podcast extra about it since it's such a bizarre tale. Fortunately, my guest on today's show, Mats Ingulstad, a professor at NTNU's Department of Modern History and Society, was equally fascinated by this little sidebar to the history of deep sea mining, so here you have it.Here are some links to relevant documents:The declassified CIA document (heavily excised) about Project Azorian, with lots of amazing detailsThe US National Security Archive's webpage describing the declassification of the CIA's Project AzorianThe US Department of State, Office of the Historian's extremely detailed description of The Hughes Glomar Explorer’s Secret Mission to Recover a Sunken Soviet SubmarineFor the definitive account of the whole affair, check out the book Project Azorian: The CIA and the Raising of the K-129.A New York Times article about the 1974 burglary that first exposed Project Azorian: https://www.nytimes.com/1975/03/27/archives/an-easy-burglary-led-to-the-disclosure-of-hughescia-plan-to-salvage.htmlThe Wikipedia page on Project AzorianThe Kennedy speech came from a 28-minute film made on behalf of the US Air Force, called Oceanography: Science for Survival. It's available from the John F. Kennedy Presidential Library and Museum.I don't talk about it, but the part of the sub that was raised also contained the bodies of six submariners, who were subsequently given a proper burial at sea. There's a video of the ceremony here.If you've read this far, I'd be interested in feedback on the sound design of this podcast. I had access to a different music library and decided to use a lot of music to see how it would sound. So let me know: was it too loud, too much, not enough? If you do send a note, make sure to tell me what kind of headphones you're using. Other comments? Questions? Fan mail? email me at nancy.bazilchuk@ntnu.no

Norway's Mid-Arctic Ocean Ridge is alive with underwater volcanic activity – where big towers called black smokers spew mineral-laden boiling hot water into the ocean. The minerals precipitate out, and have accumulated over millions of years. At the same time, this extreme environment is home to lots of weird creatures mostly unknown to science. This week, a look at the pros and cons of Norway's decision to open an area the size of Italy to extract minerals. Today's guests are Mats Ingulstad, Egil Tjåland, Kurt Aasly and Torkild Bakken.Here are links to some of the articles and opinion pieces mentioned in the show:Norway needs to know much more before actually mining the deep sea Opinion piece written by Mats Ingulstad and his colleagues at Triple Deep, first published Dagens Næringsliv, a national newspaper.This link takes you to the 17 Jan.

Our guest on today's show is Anders Hammer Strømman, one of the lead authors for the last Intergovernmental Panel on Climate Change report on mitigation of climate change, released in April 2022. He was invited to Dubai to the COP 28 climate talks to talk to the shipping industry about how they can reduce their greenhouse gas emissions. He also shares his experience – not from the negotiating rooms – but from the perspective of a scientist seeing his work being taken up by policy makers.Here's a link to the IPCC report for which Anders was one of the lead authors:https://www.ipcc.ch/report/ar6/wg3/chapter/chapter-10/You can read more about other NTNU researchers, including Helene Muri and Edgar Hertwich, who participated in the conference here:https://norwegianscitechnews.com/2023/12/climate-talks-and-the-way-forward/https://norwegianscitechnews.com/2023/12/the-energy-footprint-of-architecture-built-by-oil/https://norwegianscitechnews.com/2021/09/blocking-the-sun-to-control-global-warming/

In their careful records of climate change over the centuries — and millennia — trees offer a kind of crystal ball on the past. But they can also help researchers figure out everything from what happened in Norway during the Black Death to how Nazis hid an enormous battleship from the Allies during WWII to how much it rained in Norway during millennia past, when it was much warmer than today.Our guests on today's show are Helene Svarva and Claudia Hartl.
