Marine debris generated from the March 11th tsunami is drastically different from the ocean trash that was already plaguing our ocean. Over the coming months, there may be many difficult-to-collect debris items from the tsunami such as housing and construction materials, fishing gear and vessels. We could also find potentially dangerous items such as combustibles, as well as personal items related to the victims. Therefore, it is critical that volunteers and beachcombers document each item of debris they encounter on beaches with the highest level of scrutiny.
To assist with this effort, Ocean Conservancy created a Tsunami Debris Field Guide that highlights the most common debris items that are washing onto West Coast beaches in significantly higher numbers than in previous years. Content for the field guide was informed by our database of Cleanup data, NOAA, the California Coastal Commission and International Coastal Cleanup West Coast State Coordinators.
