After tsunami, ocean plastic acted as rafts for small sea life

After a tsunami hit Japan in 2011, hundreds of aquatic species migrated across the ocean to the US by hitching rides on debris that acted as rafts, researchers said Thursday.A total of 289 living species were found in the US on tsunami debris originating from Japan between 2012 and 2017, said the report in the journal Science."This has turned out to be one of the biggest, unplanned, natural experiments in marine biology, perhaps in history," said co-author John Chapman of Oregon State University
