Hundreds of GPS devices tracking surface currents near Deepwater Horizon spill
By Daniel Kelly
Researchers at the University of Miami have placed more than 300 GPS devices in the Gulf of Mexico since summer 2012 to study surface flow and learn how pollutants behave in normal and hurricane conditions, according to a release from the school. Flow monitoring began to see how Hurricane Isaac moved contaminants left from the Deepwater Horizon oil spill.
