As geopolitical tensions continue to reshape the Arctic, a new generation of security challenges is emerging beneath the waves. From damaged undersea cables to disinformation campaigns and covert intelligence activities, so-called hybrid threats are increasingly targeting the region’s critical maritime infrastructure, prompting governments, researchers and industry leaders to rethink how the North can be protected.
That growing concern will be at the heart of an Arctic Frontiers event in Bergen on 22 September 2026, where experts from academia, government and industry will discuss how hybrid threats are affecting defence, energy, research and the broader blue economy. Organised in cooperation with the University of Bergen and Norway’s Institute of Marine Research, the event will examine both the risks and the opportunities arising from increased investment in maritime surveillance and security. Hybrid threats occupy the grey zone between peace and open conflict. Rather than relying on conventional military force alone, they combine tools such as cyber operations, espionage, economic pressure, disinformation and sabotage to exploit vulnerabilities while maintaining plausible deniability. The concept gained international prominence following Russia’s annexation of Crimea in 2014 and has become increasingly relevant across the Arctic in recent years. The High North has already experienced incidents that illustrate these risks. Damage to submarine cables serving Vesterålen and Longyearbyen—both vital for communications, defence capabilities and civilian infrastructure—has drawn significant attention, particularly because the incidents coincided with unusual activity by Russian fishing vessels in nearby waters. While attribution remains complex, such events have reinforced concerns about the vulnerability of Arctic infrastructure. For the Nordic countries, safeguarding undersea infrastructure has become an increasingly important priority. The Arctic’s vast network of cables, energy installations, scientific facilities and shipping routes supports not only regional communities but also international communications, fisheries, offshore energy production and climate research. Any disruption can have consequences that extend far beyond the region itself. Yet the discussion is not solely about threats. Arctic Frontiers also highlights the opportunities created by this new security landscape. Greater investment in maritime domain awareness, advanced monitoring technologies and stronger cooperation among Arctic nations could significantly improve resilience while fostering innovation in ocean observation and critical infrastructure protection. As the Arctic continues to gain strategic importance, the ability to protect its maritime infrastructure may prove just as crucial as developing it. The growing focus on hybrid threats reflects a broader reality: in today’s Arctic, security increasingly depends on understanding the complex space between peace and conflict.
