Blue Heron studies the Lake

The Blue Heron, a research vessel owned by the Large Lakes Observatory at the University of Minnesota at Duluth, will be going out into the Lake today to test new equipment that will allow them to map the contours of the rock formations below the water and mud of Lake Superior. On other trips, they also research issues relating to water quality and the fish population.
