The WHOI undersea vehicle Sentry collected sonar data to create this map of the undersea asphalt mound called Il Duomo, the largest of seven similar domes in the Santa Barbara Channel. It covers twice the area of a football field and rises 30 meters, or six stories, above the seafloor. The scale at right is in meters below the sea surface.
