The Great Lakes - they provide drinking water, support recreation, and sustain fishing communities across the region. Behind the scenes, real-time observing helps protect these waters and the people who depend on them. Help us keep that work going: glos.org/donate/

The Great Lakes has seen an increase in both winter-only and, more importantly, year-round observing platforms over the past couple of years. GLOS expects these platforms to be reporting data on Seagull this winter: glos.org/2025-26-winter…

Real-time data saves lives on the Great Lakes. Observing technologies create a critical safety net for mariners, recreationists, & coastal communities. Your support helps keep this critical network online: glos.org/donate/ #greatlakes #greatlakesobservingsystem #yeahbuoy
