Abstract:

This dataset contains results from Lagrangian particle trajectory model simulations in the eastern Gulf of Mexico during May-August of 2010. Simulations used surface currents derived from altimetry products and drifter trajectories. Nondimensional skill scores (s), Lagrangian separation distances (d), velocities, and trajectories are reported.

Purpose:

To develop a regional 3D Earth System Model that includes interfacial exchange processes between sediment, water, and atmosphere; biogeochemical processes, the transport of organisms, and the effects of petroleum hydrocarbons on all of these processes.
