Potentially invasive species from the 2011 Japanese tsunami debris off the Pacific coast of North America: An ongoing international research initiative.

The catastrophic Tôhoku earthquake and tsunami of March 11, 2011 resulted in floating debris extending thousands of kilometres in the Pacific Ocean, some of which has appeared on the west coast of North America. This debris carried with it a substantial collection of non-native and potentially invasive species. 
Dr. Henry H. C. Choong will talk about an ongoing collaborative research project involving Canadian and U.S. scientists to study the biology and ecology of marine organisms on the tsunami marine debris and how ROM research and collections are important to this endeavour. The audience will be able to examine, up close, some of the organisms (hydroids), from the debris.
