If a crew can reach a spill within an hour or two it may choose containment and skimming to clean up the slick Long buoyant booms which float on the water and a skirt that hangs below the water contain the slick and keep the oil from spreading out This makes it easier to skim oil from the surface using boats that suck or scoop the oil

In flotation the technician places dried soil on a screen of mesh wire cloth and water is gently bubbled up through the soil Less dense materials such as seeds charcoal and other light material (called the light fraction) float up and tiny pieces of stone called microliths or micro-debitage bone fragments and other relatively heavy materials (called the heavy fraction) are
