Coast Guard Cutters Tackle breaks ice and creates sea smoke along the Penobscot River in Brewer, Maine, Feb. 11, 2014. The 65-foot icebreaker broke through the nearly 20-inch thick ice to allow open water to flow and the sea smoke is formed when the water temperature is much warmer than the surrounding air.
