There is concern over the large number of marine exotic organisms expected to arrive on the west coast of America from Japan, with the large pieces of floating debris that had been washed out into the Pacific by the March 11 tsunami at the time of the Great East Japan Earthquake.

Japanese scientists and other experts helped the research.
