LLO Buoy 2 -- Interactive Plotter

Large Lakes Observatory Buoy 2 (offshore)

The offshore buoy -- LLO Buoy 2 -- is located roughly 10 miles NE of Duluth and 10 miles offshore of the McQuade Harbor. You can visit the LLO buoy web page to see additional buoy data.

Here are new versions of the plotters that no longer require Java. They include the data from both buoys.

In 2019 this meteorological buoy (LLO2) was again deployed roughly 10 miles northeast of Duluth, about 10 miles offshore of the McQuade Harbor.

The focus of the research is on developing a better understanding of the thermal structure of Lake Superior, how it varies across the lake, and how it varies from year to year.
