A new specially designed light emitting diode (LED) ice buoy lantern flashes as Seaman Brett Shavack dons his hardhat for work on the buoy deck on board the Coast Guard Cutter Katherine Walker (WLM-552), homeported in Bayone, N.J. Every winter the crew replaces more than 50 aids with specially designed ice buoys that can survive the daily abuse of ice floes that plaque Hudson River commerce. USCG photo by PA2 Mike Hvozda
