Magnets Map Pollution

Polluted Waters Bear Magnetic Signature
Joseph Boyce of McMaster University in Canada and a team of researchers have come up with a way to identify contaminated sediments by their magnetic signature. By simply towing a magnetometer behind a boat, the team has shown they can scan the bottoms of harbors, lakes, and even entire coastlines for pollution, much like a treasure hunter sweeps a beach with a metal detector.
