Most vessels navigating the Bering Strait — the narrow maritime passage between Alaska and Russia — are complying with safety and environmental measures introduced by the International Maritime Organization (IMO) in 2018, according to a study published August 13, 2025.
Researchers from the University of Alaska Anchorage and Michigan State University analyzed vessel tracking data from 2015 to 2022 provided by the Marine Exchange of Alaska. They found that ships are generally using IMO-designated lanes and steering clear of “areas to be avoided,” aimed at protecting ecologically sensitive waters and reducing collision risks. The study highlights a marked shift in routes since the guidelines took effect.
The IMO measures were developed jointly by the U.S. and Russia to improve navigational safety and protect marine life in the Arctic. Despite ongoing political frictions, the findings indicate sustained cross-border cooperation in implementing the rules. Researchers noted that the system’s largely voluntary nature has not hindered high compliance rates, signaling industry acceptance of the standards.
