|The Duluth Coast Guard cutter Alder left today (above, November 29, 2010) to finish up their year’s work on Aids to Navigation before coming back in December to battle the Duluth Superior ice.
Aids to Navigation are man-made objects used by mariners to determine their position on the water or to maintain a safe course. They include buoys, day beacons, lights (lighthouses), radio beacons, fog signals, marks and other devices used to provide "street" signs on the water. Aids To Navigation include all the visible, audible and electronic symbols that are established by government and private authorities for piloting purposes. You can go here for more information.
Commander Mary Ellen J. Durley and her crew will work the Eastern side of Lake Superior, the St. Mary’s River, and Northern Lake Michigan.
