"This is a very clear threat," said John Chapman, a research scientist at Oregon State University's Hatfield Marine Science Center in Newport, Ore., where the dock float washed up. "It's exactly like saying you threw a bowling ball into a China shop. It's going to break something. But will it be valuable or cheap glass. It's incredibly difficult to predict what will happen next."
