The “pom-pom” method uses long strands of absorbent polypropylene swabs, which look like cheerleaders’ pom-poms, dragged along ocean- or river-bottom sediments to locate large areas where spilled oil has sunk. The method is in demand because it offers a rapid, low-cost results, but a marine chemist at Woods Hole Oceanographic Institution has cautioned that the method is in danger of being misused.

In November 2007, the 900-foot-long M/V Cosco Busan struck the San Francisco-Oakland Bay Bridge (not the Golden Gate Bridge in the background here). The collision tore a 200-foot hole in its hull and spilling 58,000 gallons of heavy fuel oil into San Francisco Bay. (Photo by Coast Guard Petty Officer 3rd Class Kevin J. Neff)
