De-icing the Buoy by Sidney Hermel
Summary
Coast Guardsmen clear ice from a buoy. The Coast Guard maintains the "signposts" and "traffic signals"--more than 50,000 federal aids to navigation, including buoys, lighthouses, day beacons, and radio-navigation signals--on the nation's waterways. These navigation aids provide a critical component of the overall navigational picture needed by all mariners.
