Petty Officer 1st Class Christopher Dougherty gives hand signals to the crane operator as he moves a buoy aboard an aids-to-navigation barge connected to the the Coast Guard Cutter Bristol Bay, a 140-foot ice-breaking tug, during buoy operations near Mosely Channel in Lake Erie, Nov. 27, 2012. The crew of the Bristol Bay is decommissioning some navigational buoys and replacing others as part of Operation Fall Retrieve, which is designed to limit damage done to navigational buoys during the winter months.
