The western Lake Superior Buoys are maintained by the University of Minnesota Duluth
Large Lakes Observatory, with funding from the Great Lakes Observing System.
They operate during the ice-free months each year, and are typically deployed in
mid to late spring, and recovered in mid to late fall.
The buoys are located about 10 miles northeast of Duluth, off of McQuade Harbor.
The nearshore buoy (LLO1) is located about 1 mile from shore.
The offshore buoy (LLO2) is located about 6 miles from shore.
