A debris field the size of California is headed for the U.S. West Coast. The materials were swept out to sea in March after a massive earthquake and a tsunami hit Japan.
A local oceanographer says while the bulk of the debris will take several years to arrive, items that float could hit the shores of Washington state any day now.
"My message is the debris - big objects - could be here now," said oceanographic detective Curt Ebbesmeyer. "Aircraft wings, boats, big buoys — big objects that catch the wind that can be here now."
