PORT ANGELES, Wash. >> An oceanographer who tracks flotsam says West Coast beachcombers may find floating athletic shoes with human bones as more debris from the Japanese tsunami washes ashore.

In a presentation Monday at a tsunami symposium in Port Angeles, Curt Ebbesmeyer told the audience he’s expected 100 sneakers with bones in them. He’s advising anyone who discovers human remains to call 911 and wait for police.

Ebbesmeyer also said he’s expecting 100 vessels in the next couple of years. He expects the amount of tsunami debris to peak in October and that the debris could attract a number of Japanese visitors to the Olympic Peninsula.

The Peninsula Daily News reports the three-day symposium this week in Port Angeles and Sequim was hosted in part by the National Oceanic and Atmospheric Administration.
