CARIBBEAN SEA - Fireman Jared Pearce, a crewmember aboard the Coast Guard Cutter Oak, collects oil samples from the engines and generators while on watch during the Oak's transit to Haiti Saturday, Jan. 16, 2010. Once the oil cools to room temperature, Pearce will then use the falling ball test to check the sampled oil for proper viscosity. U.S. Coast Guard photo by Petty officer 3rd Class Brandyn Hill.
