The GLOS buoy is deployed in Eastern Lake Erie, 5 miles NNW of Dunkirk in 30 meters of water. The buoy is 16 feet in length, 4 feet in diameter and weighs a little over 650lbs. It collects meteorological information including solar radiation, barometric pressure, wind speed and direction, and relative humidity, as well as wave height, direction and period information. The buoy also measures water temperature from the surface to 20m in depth, and dissolved oxygen and conductivity at 20m. Data collected are logged and transmitted via a cellular link back to the Great Lakes Center. The information collected from this buoy and from the whole GLOS system can be used for climate modeling, lake current and energy budget modeling, as well as being useful for the study of nutrient dynamics and fisheries. The system is also useful for commercial and recreational navigation by providing real time information regarding wind and wave conditions.
In the summer of 2012, buoy evidence was used to help explain a fish kill. Read the story here.
