Video: What is Boom?

By Curious

The containment boom is a temporary floating barrier used to reduce the possibility of polluting the marine environment and shorelines. Placing booms allows the oil to be concentrated on thicker surface layers, which eases its collection. Depending on the water conditions, different types of booms are used. 

CalSpillWatch has posted an informational video on the different types of boom used for containment of oil spills.
