The U.S. Coast Guard is primarily responsible for cleaning up oil spills, while NOAA experts provide scientific support to make smart decisions that protect people and the environment. There are that trained experts can use to contain or remove oil from the environment when a spill occurs. Booms are floating physical barriers to oil, which help keep it contained and away from sensitive areas, like beaches, mangroves, and wetlands. Skimmers are used off of boats and can “skim” oil from the sea surface. In situ burning, or setting fire to an oil slick, can burn the oil away at sea, and chemical dispersants can break up oil slicks from the surface., Oil is an ancient fossil fuel that we use to heat our homes, generate electricity, and power large sectors of our economy.
