    Cathedral at the end of the world

    · 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 Andüs, 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 stone

    Øystein 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:

    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 BrandtzĂŚg 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.

    · 63 Degrees North

    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.

    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.

  • Strange bedfellows: Howard Hughes, a $2 billion ship and a lost Soviet submarine

    Strange bedfellows: Howard Hughes, a $2 billion ship and a lost Soviet submarine

    · 63 Degrees North

    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 details

    The US National Security Archive's webpage describing the declassification of the CIA's Project Azorian

    The 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 Submarine

    For 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.html

    The Wikipedia page on Project Azorian

    The 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?

    Seabed mining – savior or scourge?

    · 63 Degrees North

    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.

  • 1100 Norwegian teachers fought Hitler — and won

    1100 Norwegian teachers fought Hitler — and won

    · 63 Degrees North

    When Hitler's troops stormed into Norway on April 9, 1940, Germany's goal was to secure the country’s 1200 km long coastline so iron ore from Swedish mines could continue to flow to the northern Norwegian port of Narvik — and eventually to the German war machine. 

    But that wasn't all that Hitler and his followers hoped for, as Norwegian teachers would come to learn.

    Vidkun Quisling, a Nazi collaborator who nominally headed the Norwegian government during the occupation, wanted Norway to embrace Nazi ideology. He decided the best way to do this was through teachers and schoolchildren. In February 1942, he ordered all teachers to join a new union that would require them to introduce Nazi doctrine to their students. Students were also ordered to join the Norwegian equivalent of the Hitler Youth.

    But the teachers refused.

    They organized using tactics right out of a spy movie to resist — scribbling messages in invisible ink, meeting secretly in basements and train stations, and printing newsletters to coordinate efforts across the country. For their efforts, 1100 were arrested — and subjected to months of starvation, torture and hard labour.


    This week, the story of what happened when the teachers defied Hitler — and won!

    My guests on today's show are Martin Øystese and Unni Eikeseth.

This week, I head to Iskoras mountain, a low peak in far northern Norway, outside of the town of Karasjok to find out what burying tea bags in the tundra — and doing sophisticated measurements in a peat bog —can tell us about the future of permafrost and its effects on the climate.

    Norwegian technology, courtesy of the 19th-century whaler Svend Foyn, played a critical role in establishing the modern era of industrial whaling.By the time the 1960s rolled around, most large whale populations hovered on the brink of extinction. Now, Norwegian researchers are testing new technologies so they can track and study these marine giants — and help protect them. This week, tapping into fibre-optic cables to eavesdrop on whales in a way that's never been done before— and how deploying a comprehensive library of whale dialects can help prevent ship-whale collisions in busy California shipping ports.

    Running rats and healing hearts

    · 63 Degrees North

    In 1998, a young Norwegian exercise physiologist found that a technique he had used to help Olympic athletes could help heart patients too. But his idea made doctors sweat. One famous cardiologist told him that if he used his technique in human heart attack patients, he "would kill them."

    Today's show looks at what happened when our researcher, Ulrik Wisløff, defied the experts — and built a career learning how high intensity interval training can help everyone from heart patients and ageing Baby Boomers, and possibly even Alzheimer's patients — but not in the way you might think!

  • Wax, wood and CO2

    Wax, wood and CO2

    · 63 Degrees North

    Three tons of wax. A 4-story office building made almost entirely of wood. And putting CO2 to work instead of letting it heat up the planet: Scientists and engineers across the globe are harnessing unlikely materials to cut greenhouse gas emissions.

    Today's show looks at how a zero-emissions office building combines integrated solar panels, heat pumps and a huge vat of wax to heat and power the structure, with enough left over to sell. We'll also look at highly efficient heat pumps using CO2 as the stuff inside that makes it work. They're spreading worldwide, and can be found everywhere from inside your Volkswagen ID electric car to the Large Hadron Collider. And also — at a hotel in Hell, Norway, where electricity use was cut by 70 per cent — without making a pact with the devil!

    Our guests on today's show are Tore Kvande and Armin Hafner.

    There's a video on Professor Hafner's work at CERN here, and more about CoolCERN, here.

  • The EU has the strongest climate law in the world. But it's not enough.

    The EU has the strongest climate law in the world. But it's not enough.

    · 63 Degrees North

    Earlier this year, tremendous floods in Pakistan forced 600,000 pregnant women to leave their homes for safer ground. It was among the latest in a series of nearly unthinkable happenings caused by climate change."Can you imagine if you are about to give birth to a child, and you have to leave your home and flee? These are very traumatic experiences that people have now in all continents, and increasing frequency," says NNTU Professor Edgar Hertwich. He says we all know now that climate change is no longer an abstraction — it's here, and humankind has to act.

    Hertwich — one of the top 100 climate researchers on the planet — is in a unique position to push the international agenda: he's one of just 15 members on the European Scientific Advisory Board on Climate Change, which is advising the EU on implementing its new climate law. That matters because the EU is the largest political entity in the world to commit to such ambitious goals.

    The 27 nations in the EU have committed to cutting their carbon emissions by at least 55% in just 8 years — by 2030. By 2050, the EU law commits its member nations to a net-zero emissions balance — meaning that they will reduce its greenhouse gas emissions as much as they can and find ways of compensating for the remaining and unavoidable emissions so that the net emissions are zero.

    This is an aggressive plan, Hertwich says, but it doesn't go nearly far enough. And he's been vocal in telling EU leaders just that. Listen to what he had to say to a recent EU Strategy Summit on Climate in Brussels, hosted by NTNU and SINTEF, Scandinavia's largest independent research institution.

    You can read a collection of popular science articles about Professor Hertwich's research here.

    Here's a selection of his recent academic publications:

  • Getting to Net Zero

    Getting to Net Zero

    · 63 Degrees North

    We all know that climate change is real and that we have to do something about it. In today's podcast extra episode, we go behind the scenes at the Intergovernmental Panel on Climate Change, and talk to Anders Hammer Strømman, who was one of the lead authors for their latest report, released in April this year. Anders is a professor at NTNU's Industrial Ecology Programme where he has specialized in Life Cycle Assessment and Environmental input-output analysis, which are tools that enable us to understand the real environmental costs of the goods and materials we use in everyday life.


    We talk about why cutting carbon emissions quickly is a little like skiing up a big mountain, how battery companies need to come clean when it comes to how they make their products, why some version of a home office could be good for the planet, and why your individual choices can actually make a difference.  And we talk about why Anders is optimistic and thinks we can make this shift — even though the governments of the world have been slow to act.


    Anders encouraged me (and by extension, you, my listeners) to look at the entire report (nearly 3000 pages — not 3675 as I say in the podcast!) but that's probably more than most of us have time for. You can look at the chapter that Anders was lead author on, on Transport, here (the link will start a pdf download). You can read an even more condensed version of the WG III report and its major findings here.


    The bottom line is that we CAN make this happen!


    Thanks this week for help from Ole Marius Ringstad, who did the sound design for the episode. Stay tuned for an update about next season, coming in the autumn.

    The Alchemists: Turning wild water into white coal

    · 63 Degrees North

    The secrets behind how Norwegian scientists and engineers harnessed the country’s wild waterfalls by developing super efficient turbines — and how advances in turbine technology being developed now may be the future in a zero-carbon world. They include an engineer who figured out how to take advantage of national fervour and build the 1900s equivalent of a super computer, a WWII resistance fighter who saw something special in tiny temperature differences, and researchers today, who are finding ways to cut environmental impacts from current hydropower plants and craft the designs we need to confront climate change.


    The guests on today's show were Ole Gunnar Dahlhaug, Vera Gßtle and Johannes Kverno, with cameo appearances by Hans Otto Frøland and Svein Richard BrandtzÌg.

  • Pirates, noblewomen and bicycling housewives

    Pirates, noblewomen and bicycling housewives

    · 63 Degrees North

    Why does Norway always rank among the top countries on the planet when it comes to gender equality? It didn't happen by accident. Instead, it took powerful medieval noblewomen, 19th century farmers’ wives, an early 20th century activist on a bicycle, and the feminists who emerged from the postwar baby boom. And yes, there is one Viking woman — but she’s not quite what you might think.


    Our guests on today's show are Randi Bjørshol WÌrdahl, Kari Melby and Marie-Laure Olivier.
