Summary: The 2011 Tohuku earthquake and tsunami in Japan sent plenty of debris across the Pacific. Boats, docks, and more ended up on Oregon beaches. And they were occupied; not by people, but by species unknown on this side of the ocean. How big an effect was it, and how common is "species rafting?" These questions are explored in a recent report by scientists at the Oregon Institute of Marine Biology and the Hatfield Marine Science Center of Oregon State University.
