As the March 2011 earthquake and tsunami wreaked devastation on land, it also washed tons of debris into the sea. Heavy debris settled to the ocean floor, but buoyant debris continued to drift out to the open ocean. This debris could reach the west coast of the Americas as early as this winter, according to scientists at the National Oceanographic and Atmospheric Administration.

Even with sophisticated modeling, some uncertainty exists about what is still floating and where it will go. There are even concerns that some of this debris may be contaminated by radiation from the melted-down Fukushima  Daichi nuclear plant. Recently, a large piece of debris found on a beach in Humboldt County, Calif., was the cause of such concerns and prompted a response by the local Office of Emergency Services, state and federal agencies. The object and persons who came in contact with it were monitored and determined to be free of radioactive materials, however it raised concerns about the potential hazards of beach debris whether or not they pose a threat of radioactivity.
