What is deep-sea mining, and why are countries and companies racing to the ocean floor for critical minerals?

In this episode of GNSI’s “At the Boundary” podcast, host Jim Cardoso speaks with Dr. LindaNhon about the growing global debate over deep-sea mining and what it could mean for national security, critical minerals, and environmental risk.

The two dive into the mining of polymetallic nodules, mineral-rich deposits found on the seabed that contain cobalt, copper, and manganese. These materials are essential for technologies ranging from electric vehicle batteries to defense systems and advanced industrial supply chains. As demand for critical minerals rises, deep-sea mining is increasingly being viewed as both an economic opportunity and a geopolitical challenge.

Dr. Nhon explains the key questions shaping the future of seabed mining: What are the environmental consequences of disturbing the ocean floor? Who should regulate access to these underwater resources? And how can governments balance the need for mineral security with scientific transparency and international cooperation?

If you want to understand how the competition for ocean resources could shape the future of energy, defense, and global power, tune in to the episode! It not only sheds light on the matter at hand, but also offers modern solutions for policy makers and officials.

At the Boundary from the Global and National Security Institute at the University of South Florida, features global and national security issues we’ve found to be insightful, intriguing, fascinating, maybe controversial, but overall just worth talking about.

A "boundary" is a place, either literal or figurative, where two forces exist in close proximity to each other. Sometimes that boundary is in a state of harmony. More often than not, that boundary has a bit of chaos baked in. The Global and National Security Institute will live on the boundary of security policy and technology and that's where this podcast will focus.

The mission of GNSI is to provide actionable solutions to 21st-century security challenges for decision-makers at the local, state, national and global levels. We hope you enjoy At the Boundary.

The last major nuclear arms control treaty between the United States and Russia has ended. What happens next?

In this episode of “At the Boundary,” host Jim Cardoso speaks with nuclear policy expert Heather Williams, director of the Project on Nuclear Issues (PONI) and a senior fellow in the Defense and Security Department at the Center for Strategic and International Studies (CSIS), about the expiration of the New START Treaty, the last remaining bilateral nuclear arms control agreement between Washington and Moscow.

Drawing from her recent analysis, Williams explains three key truths about the end of New START and what they reveal about the future of nuclear strategy, deterrence, and global security. The conversation explores whether the treaty’s expiration signals a new nuclear arms race, how the United States might adapt its nuclear posture, and why future arms control efforts may need to include China alongside Russia.

Williams also emphasized the importance of new ideas in nuclear policy, encouraging the next generation of strategists to rethink how arms control can manage risks in a rapidly changing geopolitical environment.

From nuclear modernization to deterrence strategy and the future of nonproliferation, this episode provides a clear and accessible look at one of the most consequential shifts in global security.

In this episode of At the Boundary, GNSI’s Strategy and Research Manager, Dr. Tad Schnaufer II, is joined by Dr. Louise Tumchewics, a professor at the Center for War Studies at the University of Southern Denmark. They discuss Tumchewics’ upcoming project with the Center that focuses on the nexus of cybersecurity, geopolitics, and supply chain resilience for average businesses in Denmark.

Tumchewics mentions the human aspect of cybersecurity, and how Denmark is working to educate its civil population on digital security. She mentions that a cyberattack to critical infrastructure, such as the 2017 Maersk shipping crisis, would be damaging to the Danish supply chain and the Danish people, who rely heavily on online services. She ends with a hopeful look to the future, where countries like Denmark could have effective plans in case of cyber or hybrid threats.
