Drifter trajectories calculated from geostrophic currents
In this page you can see drifter trajectories over the Gulf of Mexico (at the Yucatan Strait, Mississippi River delta and Florida Straits) calculated from geostrophic surface currents. Sea Surface Anomaly (SSA) fields are taken from the CLS Space Oceanography Division (Collecte Localisation Satellites, http://www.cls.fr). A HYCOM mean Sea Surface Height (SSH) is used to obtain absolute SSH, which is used to calculate the geostrophic currents. The trajectories are calculated using a Runge-Kutta second order scheme, and they are calculated each 6 hours. Here the drifter trajectories are superimposed to our OI SST product.

The outflow of the Mississippi River was being rapidly transported to the Florida Keys. The Katrina Tracking Tool helped to better understand and predict the fate of the Mississippi water.
