Deploying the LLO buoy in 2008

In 2014 this meteorological buoy (LLO1) was again deployed roughly 10 miles northeast of Duluth, about 1 mile 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.

Deployment Dates:
2008: 16Jun - 28Oct
2009: 28May - 16Nov
2010: 16Jun - 24Nov
2011: 12Apr - 09Nov
2012: 18Jun - 13Nov
2013: 07May - 30Oct
2014: 18Jun -
