A three-dimensional view of the scour mark caused by a hard object on the seafloor as mapped by NOAA Ship Okeanos Explorer. The image shows the sonar reflection intensity (backscatter) in black and white, as draped over the topography of the seafloor. White indicates a strong reflection and hard substrate. The depth of this feature is 330 meters (1,083 feet). Though thought to possibly be a shipwreck, the bright mound ended up being a rocky reef habitat.
