The NOAA research vessel Okeanos Explorer recently stopped by Unalaska. The crew is mapping the floor of the Bering Sea as part of Seascape Alaska, a five-month project that started in May of this year.
Currently, about half of the seafloor within U.S. waters remains unmapped, according to NOAA. That means a ship with deepwater exploration capabilities — like the Okeanos — is crucial to understanding what lies below the surface of waters beyond the coastline.
