I sit down with Lyle Trytten—nicknamed the “Nickel Nerd”—a chemical engineer and metallurgical consultant specializing in critical minerals and sustainability. With decades of experience from mining operations to refining and supply chains, Lyle breaks down the complex realities behind the recent surge of tariffs and trade tensions between the U.S. and Canada—and their potential consequences for critical mineral supply chains.
Lyle explains why tariffs meant to encourage domestic processing might backfire, raising costs and making U.S. manufacturing less competitive globally. He also details just how reliant the United States is on Canadian imports, especially for nickel and cobalt—critical minerals essential for the energy transition.
Plus, we discuss Canada's response, how trade tensions are influencing market sentiment, and what policymakers and industry need to understand to navigate the intricate balance of economic nationalism, geopolitical tensions, and global supply chain realities.

Dorothy Dankel joins Eric to discuss her recent paper with Min Hyung Kim on how society should navigate the epistemic authority of science and how we need to be ‘ready to be wrong’ and be more comfortable with the fact of uncertainty. This conversation delves into the complexities of deep sea mining, the intersection of journalism and scientific research, and the philosophical underpinnings of science. The discussion highlights the importance of collaboration in scientific endeavors, the challenges posed by uncertainty in research, and the implications of post-normal science in understanding environmental issues. The conversation also emphasizes the need for more deep sea research and the potential risks and opportunities associated with deep sea mining.
Dorothy is Senior Research Scientist at SINTEF Ocean and adjunct assoc. professor at the Dept. of Biological Sciences, University of Bergen in Norway. Her expertise is in Responsible Research and Innovation (RRI) and transdisciplinarity in Marine Science. She is Chair of the Nordic Marine Think Tank and has been a fellow at the University of Massachusetts, Dartmouth, School of Marine Science and Technology (SMAST) and the International Institute of Applied Systems Analysis (IIASA).

Eric is joined by journalist Elyse Hauser, whose work on deep-sea mining brings a much-needed depth to a topic often superficially covered. Elyse shares her transition from marketing to journalism, motivated by her passion for environmental integrity and her deep connection to aquatic environments.
We delve into how deep-sea mining is portrayed in the media, the misconceptions prevalent in public discourse, and the complexities overlooked in mainstream narratives. Elyse discusses the journalistic challenges and responsibilities in covering such a multifaceted subject, emphasizing the need for greater investigative depth and critical analysis.
Elyse’s Substack Notes From the Deep is a treasure trove of information, entertainment, and nuance on all things deep sea.

This podcast has 3 aims
1- to share knowledge about deep sea mining, and about the drivers of the deep sea mining conversation: critical minerals, ecosystem integrity, geopolitics, ethical values.
2- to give access to viewpoints from all sides of the deep sea mining conversation. So that those involved have a chance to be heard and understood and to hear and to understand one another.
3- To explore the central issues of sustainability, externalities, and the energy transition through the test case of deep sea mining.
Philosophers like to choose artificially extreme versions of real world problems as thought experiments to help explore a point. I was originally attracted to deep sea mining as a thought experiment for the material impacts of the energy transition and the difficult trade-offs that we are forced to face. Deep sea mining is a useful test case for many of these ideas, both because it is a quintessential dilemma of the current moment, and because the nuances and details which are often being left out of the conversations are crucial for understanding and for making responsible decisions.
Going forward I will release interviews with key deep sea mining experts as well as relevant thinkers on related topics.
