Japanese Dock Invasive Species
A floating dock that unexpectedly washed ashore in Newport this week and has been traced back to the Japanese disaster has brought with it a completely different threat – invasive species. Scientists at Oregon State University’s Hatfield Marine Science Center said the cement float contains about 13 pounds of organisms per square foot, and an estimated 100 tons overall. Already they have gathered samples of 4-6 species of barnacles, starfish, urchins, anemones, amphipods, worms, mussels, limpets, snails, solitary tunicates and algae – and there are dozens of species overall.
