NASA: Animation of Tsunami Debris

Another visualization from the wizards at NASA, this time illustrating the likely drift of the debris unloosed by Japan's 2011 tsunami. (via Julia Whitty's Blue Marble blog)

This animation shows the output of the Surface Currents from Diagnostic (SCUD) model, an attempt to simulate where and how that debris would disperse. Orange and red shaded areas represent parcels of water with a high probably of containing floating debris. The deeper the red color, the higher the likely concentration. The debris field stretches roughly 5,000 kilometers by 2,000 kilometers across the North Pacific.
