A scientist who examined the dock that recently washed ashore on Washington’s Olympic Peninsula says it looks just like the one that came ashore on a central Oregon beach last summer, suggesting it also is a piece of tsunami debris from Japan.

John Chapman, an assistant professor of fisheries at Oregon State University’s Hatfield Marine Science Center, said Friday the Washington dock found earlier this month has the same dimensions and configuration as the one found near Newport, Ore. The Oregon dock broke loose from a Japanese fishing port in 2011.
