HONOLULU (AP) — Lumber, boats and other debris ripped from Japanese coastal towns by tsunamis last year have spread across some 3,000 miles of the North Pacific, where they could wash ashore on remote islands north of Hawaii this winter.
The National Oceanic and Atmospheric Administration estimated the first bits of tsunami debris will make landfall soon on small atolls northwest of the main Hawaiian Islands. Other pieces were expected to reach the coasts of Oregon, Washington state, Alaska and Canada between March 2013 and March 2014.
NOAA's tsunami marine debris coordinator, Ruth Yender, told an online news conference Tuesday that agency workers were boarding Coast Guard flights that patrol the archipelago. NOAA also asked scientists stationed at Midway and other atolls to look for the debris.
Debris initially collected in a thick mass in the ocean after tsunamis dragged homes, boats, cars and other parts of daily life from coastal towns out to sea. Most likely sank not far from Japan's eastern coast.
In September, a Russian training ship spotted a refrigerator, a television set and other appliances west of Hawaii. By now, the debris has likely drifted so far apart that only one object can be seen at a time, said Nikolai Maximenko, a University of Hawaii researcher and ocean currents expert.
One to 2 million tons of debris remain in the ocean, but only one to 5 percent of that could reach Hawaii, Alaska, Oregon, Washington state and Canada's British Columbia, Maximenko said. The tsunamis generated a total of 20 million to 25 million tons of debris, including what was left on land.
Yender said that so far, no debris confirmed to be from the tsunamis has landed on American shores, including large buoys suspected to be from Japanese oyster farms found in Alaska last year. The buoys would have had to travel faster than currents to get to Alaska at that time if they were set loose by the March 11 tsunamis.
