There is some concern about potential invasive species exposure.Among the non-native organisms clinging to the dock are a speciesof tiny crab that has invaded the U.S. Atlantic coast but not thePacific coast, and an algae found in southern California but not inOregon. The Oregon Parks and Recreation Department is working with theOregon Department of Fish and Wildlife to contain this threat. The state of Oregon is still developing disposal options.

Twopossibilities are salvage or demolition; both are being evaluated. Scientists with the National Oceanic and Atmospheric Administrationhad predicted that some of the debris from the Japanese earthquakeand tsunami would reach U.S. and Canadian coasts over the nextseveral years. NOAA and University of Hawaii models suggest themajority of the debris will begin to arrive in 2013, and theCanadian government agrees. Oregon Senator Ron Wyden says coastal residents should be preparedfor more tsunami debris, which is crossing the Pacific more quicklythan anticipated. Aluminium Composite Signs Manufacturer
“The huge dock that washed ashore in Agate Beach is clear evidencethat debris from last year’s tsunami in Japan is reaching theOregon Coast much sooner than anyone predicted,” Wyden said today.”This massive dock, which crossed the Pacific Ocean undetected in15 months, may be the vanguard of more debris to come.” “With the strong possibility that more debris could pose asignificant threat to shipping lanes and fishing grounds,” Wydensaid, “I encourage the National Oceanic and AtmosphericAdministration to redouble its efforts in tracking debris generatedby the Japanese earthquake and to work closely with other federal,state and local agencies to inform the public how best to reportsuspected debris.” Some tsunami debris has already washed up on the shores of BritishColumbia. Earlier this year, an unmanned vessel from Japan wassighted off the islands of Haida Gwaii on the northern BC coast,and a shipping container from Japan with a motocycle inside wasfound in Naikoon Provincial Park, also on Haida Gwaii. In April, people in Alaska found Japanese soccer ball. Floatingmaterial, including buoys and Styrofoam washed up on MontagueIsland, about 120 miles southeast of Anchorage. China Rolled Aluminum Plate
On April 5, an unoccupied fishing trawler that U.S. officials saidwas torn from its moorings by the tsunami was sunk by a U.S. CoastGuard vessel after it entered Alaskan waters and posed a hazard tonavigation. Copyright Environment News Service (ENS) 2012.
