Surface River Drifters

These drifters were initialized with the fresh water of the Atchafalaya and Mississippi rivers. The circle shows the current location of the drifters, and the tail shows several days of previous positions. There was more river water in 2008, leading to a large pool of fresher water on the shelf as compared with 2007; this is reflected in the drifter positions.
