tsunami debris


The tsunami that struck Japan four years ago sent about five million tons of debris into the Pacific Ocean. On Friday, workers started unloading one million pounds of that debris that arrived by barge in south Seattle.

Oregon scientists are trying to figure out how a fish, native to Japan, was pulled out of a crab pot on the Oregon coast - alive.

“I’ve been thinking about it ever since I heard about it,” says John Chapman, an invasive species expert at the Hatfield Marine Science Center.

He says there’s only a handful of ways the striped knifejaw could make it here: in the ballast water of a ship; someone could have dumped their aquarium into the ocean; or the fish survived under debris washed out to sea after the Japanese tsunami.

Winter storms off the Oregon and Washington coastlines are expected to bring a new wave of debris from the 2011 tsunami in Japan. Scientists say objects are already washing ashore – with potentially invasive organisms riding along.
