For three decades, Russian and Western scientists shared data across the Arctic without incident: toxin levels in Indigenous blood, permafrost melt rates, nuclear contamination maps. The Kremlin signed off on all of it. Now it's arresting the scientists who did the sharing.

The recent high-treason arrest of Arctic medical researcher Alexey Dudarev in Saint Petersburg marks the clearest sign yet of how far the collapse has gone.

A career built on open science

As a leading researcher at a major Rospotrebnadzor center, Dudarev served as a Russian-nominated expert for the Arctic Monitoring and Assessment Program (AMAP) Human Health Assessment Group. He co-authored regular AMAP reports published as open-access documents and contributed to numerous international scientific journals, many of which remain archived in the US National Library of Medicine.

His work grew from a foundation laid in the early 1990s, when the collapse of the USSR opened the Arctic to genuine scientific diplomacy. Norwegian research centers led the way, initiating dozens of joint projects with Russian counterparts, including a two-decade study on the aftermath of nuclear tests on Novaya Zemlya and threats from scuttled nuclear submarines.

In 2015, Salve Dahle, head of the Norwegian institute Akvaplan-niva, described such cooperation as "very useful," a sentiment echoed even by Russian military-industrial outlets at the time.

By the early 2000s, AMAP research had reshaped understanding of the region. Dudarev's work on persistent toxic substances and Indigenous peoples of the Russian North dismantled the myth of a pristine Arctic, showing that global atmospheric circulation deposits toxins into the food chain through fish and reindeer meat, creating significant health risks across industrial development zones. He warned that without a national monitoring program, dangerous "blind spots" for public health would emerge.

Moscow turns the Arctic into a fortress

Russian participation in international cooperation began declining after 2010, when a new Arctic strategy designated the region primarily as a resource base. Research focus shifted from environmental health to securitization and development of the Northern Sea Route as a national transport artery.

Beginning in 2013, Russia restored Soviet-era military infrastructure across the High North. A December 2019 BBC Russian Service report described major construction on Novaya Zemlya, including expansion of the Rogachevo airfield and deployment of S-300 and S-400 air defense systems alongside Rezonans-N radar systems capable of monitoring Arctic airspace across thousands of kilometers.

The 2014 annexation of Crimea and resulting Western sanctions further stifled collaboration. Western grants and foundations scaled back programs with Russian state institutes, while Moscow increasingly viewed academic exchanges as a potential risk for sensitive information leaks.

Mikhail Komin, a visiting fellow at the European Council on Foreign Relations, wrote in May 2025 that "over the last decade, the Arctic has become a strategic priority for Russia, second in importance only to its relations with post-Soviet states, including Ukraine."

The full-scale invasion of Ukraine in February 2022 brought international projects to a halt. Two months later, Putin convened a meeting demanding the "maximum acceleration" of both economic and military Arctic expansion. The term "development" -- osvoyeniye -- returned to the official lexicon, a direct echo of Imperial and Soviet expansion when conquering northern frontiers symbolized national power. Research that had been open and collaborative for decades, including public health data and social statistics, was suddenly viewed through the lens of national security.

Loyalty to science, paid in prison time

On January 14, Dudarev was detained in Saint Petersburg on charges of high treason. The human rights project Perviy Otdel reported the arrest February 6, noting that after a search of his apartment, investigators sent him to a pre-trial detention center.

Authorities allege that data from his scientific publications "could have been used by Norwegian intelligence." Colleagues and lawyers dismissed the charge as baseless, pointing out that all materials in question were already in the public domain.

Dudarev's arrest may have been triggered specifically by his contributions to open AMAP publications, according to T-invariant, an outlet serving the community of scientists who have left Russia.

"These weren't just studies," Ilya Shumanov, founder of the Arktida project, told T-invariant. "Dudarev demonstrated how toxic exposure affects the health of women and children. This is an extremely sensitive topic for the Russian authorities: it brings to light very unsavory stories regarding the aftermath of barbaric environmental practices and the disregard for the needs of Indigenous populations."

Dudarev never held a security clearance, signed no non-disclosure agreements, and never worked within classified Defense Ministry institutes. His research has hundreds of citations on Google Scholar and received publication clearance from state agencies in every AMAP member nation, Russia included.

His case is not an aberration.

According to human rights data published by The Insider in January, Russia convicted 468 people of high treason and espionage in 2025 alone, with at least 1,627 individuals currently facing such charges. In 88% of cases, prosecution began after February 2022.
