First Fukushima Debris Washes Up In Olympic Peninsula

PORT ANGELES — The first piece of debris that could be identified as washing up on the West Coast from the March 11 tsunami in Japan — a large black float — was found on a Neah Bay beach two weeks ago, Seattle oceanographers Curtis Ebbesmeyer and Jim Ingraham said Tuesday night.

Since then, the two researchers, known as DriftBusters Inc. — who have used flotsam to track wind and water currents in the Pacific since 1970 — have learned that the black, 55-gallon drum-sized floats also have been found on Vancouver Island.

Ebbesmeyer and Ingraham spoke to more than 100 people at Peninsula College and brought the float with them, along with examples of other items that may be showing up on beaches in the next year.

Tons of debris washed out to sea when a tsunami struck northern Japan after a massive magnitude-9.0 earthquake March 11.

About a quarter of the 100 million tons of debris from Japan is expected to make landfall on beaches from southern Alaska to California, possibly in volumes large enough to clog ports, Ebbesmeyer said.

Using models from a historic shipwreck that occurred 20 miles off Neah Bay, Ebbesmeyer and Ingraham have determined the path of debris that comes into that area off the Washington coast.

They said debris will be snagged by currents leading into the Strait of Juan de Fuca and that a large portion of it will end up on beaches from the mouth of the Elwha River to Port Townsend.

Many ocean models have shown that the massive congregation of flotsam that washed away from devastated Japanese coastal cities is in the middle of the Pacific and won’t make landfall in the U.S. for another year or two.

Most of it is exactly where those models predicted, but those models don’t take into account wind and flotsam with large areas exposed to the wind, said Ebbesmeyer, who became famous for his and Ingraham’s ocean research into currents after large spills of Nike shoes and bath toys from container ships in the 1990s.
