Marine debris is beginning to arrive from Alaska to Oregon. The local authorities there are gearing up for identifying types of debris so that studies can be made. If one wishes to participate locally, organize to ask local administrations to begin the identification process of debris before the field washes ashore in quantity. Organize groups to comb beaches and photograph, identify and catalog types of debris that will be arriving on our shores.
There is an app for Android and iPhones to assist with beach cleanup as it allows a short description of the items and a local place name where the debris can be found and a database is built for cleanup crews.
