As we reported on earlier today, a massive concrete dock has washed ashore in Agate Beach, Oregon, its origins having been somewhere in Japan before it was set adrift in the devastating 2010 earthquake. Although there has been some concern in regard to radioactive materials surfacing, one thing scientists are not overlooking is the potential threat that invasive organisms could have to our native coastal ecosystems. The dock is harboring more than 100 tons of biological life forms, of which researchers have been instructed to remove and collect for identification and study purposes. There is no way to determine if some species have already infiltrated the ecosystems, so scientists will be monitoring coastal areas for any indications that an invasion has begun. Check out this footage that was taken very recently of the enormous size of this structure and a few of the hitchhikers it carried all the way here.
