RV Blue Heron


RV Blue Heron is a research vessel serving on the Laurentian Great Lakes. She is owned by the University of Minnesota Duluth, and operated by the Large Lakes Observatory in partnership with the University-National Oceanographic Laboratory System. The Blue Heron is the largest research ship owned by a university operating on the Great Lakes, and the second-smallest UNOLS vessel by LOA.

History

The Blue Heron was built in 1985 as a fishing vessel and christened Fairtry before being purchased by the University of Minnesota in 1997 and converted to a research vessel for deployment in 1998. The ship celebrated its 25th year of scientific service in 2023.
In September 2024 the crew discovered an unknown microorganism in a substance on the ship's rudder shaft while docked at the The [Great Lakes Group#Great Lakes Shipyard (GLS)|Great Lakes Shipyard] in Cleveland, Ohio. Researchers gave the microorganism the placeholder name of "ShipGoo001".

Activities

The Blue Heron conducts limnological research on the five Great Lakes throughout the ice-free season. Its capabilities include water and sediment sampling and analysis, sensor launching and retrieval, and radar/sonar scanning. In addition to its research capabilities, the ship also hosts public science outreach and education events in Duluth and other communities.
