Great Lakes Shipyard, Cleveland, OH, finished the 5-year overhaul work on the U.S. Geological Survey Research Vessel Grayling. Under a Fleet Maintenance Contract with the Great Lakes Science Center, Ann Arbor, MI of the U.S. Geological Survey, Department of the Interior, the Grayling was drydocked and given a detailed inspection, cleaning, tune up, repair and modifications. Some of the major work items included overhauling the generators and engines, painting the hull, and repairing of the exhaust and propulsion systems. The 75 ft. long Grayling was built in 1977 and is home-ported in Cheboygan, MI. The Grayling is the Center's third largest vessel with great geographic range and advanced scientific abilities. Nearly all of the fish population and habitat research in Lake Huron is conducted aboard this research vessel. The Grayling is also used in fish population assessment in eastern Lake Superior. As the Nation's largest water, earth, and biological science and civilian mapping agency, the U.S. Geological Survey (USGS) collects, monitors, analyzes, and provides scientific understanding about natural resource conditions, issues, and problems.
