Striations imaged with sidescan sonar backscatter are shown for a portion of the central dome at Atlantis Massif, location shown by blue box on inset. DSL120 tracklines angle across this area and a small portion of underlying TOBI data (where striations are labelled) illustrates the difference in resolution, 2-m pixel versus 10-m pixel size, respectively, of these systems. Dark indicates low backscatter; white indicates high backscatter. Grid marks 1-km subareas aligned in the UTM reference frame.
