Here is a disturbing story showing the devastation that can be wrought by a single event. The upside to this is that it CAN be fixed with enough effort and some of that BP settlement money.
This is happening just off the coast of my home state, Louisiana. The OROV project would be just about perfect for researching the waters around these islands. I can see using payloads such as Doppler flow profilers to analyze currents in an effort to optimize the restoration efforts for these islands in the Gulf of Mexico.
