Real-time AIS tracking for St. Paul and St. George Islands
This page provides real-time marine vessel tracking for the Pribilof Islands using AIS (Automatic Identification System) technology. We operate two VHF AIS receiversāone on St. George Island and one on St. Paul Islandāthat continuously monitor vessel traffic in the Bering Sea.
How it works: Commercial vessels, fishing boats, and Coast Guard ships broadcast their position, speed, heading, and identification via VHF radio signals. Our receivers pick up these signals and display them in real-time. The AI-powered Marine Traffic Observer analyzes current vessel activity and provides commentary about what's happening in the area.
Alert system: When vessels come within 20 nautical miles of either island, a red alert banner appears at the top of the page. Vessels are categorized as "Approaching" (within 20nm) or listed under "All Other Vessels" for everything else detected by our receivers.
Note: AIS relies on line-of-sight VHF signals. Not all vessels have AIS transponders, and some may turn them off. Range varies based on vessel height, antenna placement, and weather conditions. This data is for informational purposes only and should not be used for navigation.
AI Disclaimer: The Marine Traffic Observer commentary is generated by artificial intelligence for entertainment purposes. While it uses real vessel data, the AI may occasionally make mistakes, misinterpret information, or add creative embellishments. Always refer to the actual vessel data below for accurate information.
