The Research Vessel Blue Heron, owned and operated by the University of Minnesota, is a highly capable research platform supporting the work of Great Lakes scientists for the last two decades. The Blue Heron has a crew of five and can support up to six scientists for cruises as long as 10 days. While she spends most of her time in Lake Superior, recent work has taken the Heron to Lakes Huron, Michigan, and Erie. Physicists, geologists, biologists and chemists all use the Heron as a way to access the waters of the Great Lakes.
