This model demonstrates how ocean surface currents function in transporting drifting objects on the ocean surface. A drifter is a buoyant object which remains near the surface of the ocean and is not influenced in movement by internal power but rather by the oceans currents. When using this model, you could imagine dropping a corked bottle or a coconut into the ocean at a given location and observing where the object would end up as a result of surface currents. This model uses ocean currents measured by ship-drift (A. J. Mariano, Rosenstiel School of Marine and Atmospheric Science, data) and their standard deviations to predict the probable motion of Ship Drifts.
