Abstract
A floatable oil sweep useful in controlling an oil spill on a moving body of water comprises an elongated web of oil sorbent adapted to float on the body of water with its large-area faces parallel to the waterline, and a weighted open-mesh netting attached to the web and adapted to be suspended below the floating web when the oil sweep is deployed. Use of the netting has been found to significantly extend the period of time before oil droplets are carried under the oil sweep by movement of the body of water.
