An Oil Spill Trajectory Model

Scientists used computer models to predict how spilled oil from the Exxon Valdez would travel across Prince William Sound, Alaska, during the first week after the spill in March 1989. Predicting the direction in which oil will spread from a spill is an important part of the response strategy. Trajectory models help guide recovery efforts by showing which locations are most likely to need resources, such as lengths of boom, to protect the shoreline. (Photo credit: OR&R, NOAA)
