This three-dimensional seismic map of the bathymetry and amplitude of Atwater Valley 340 (AT 340) provides a visual representation of the subsea depth and strength of the response of sound energy bouncing off the sea floor. The "hard" returns (shown as red, yellow, and dark green areas) indicate hardbottom habitats — many of which also have chemosynthetic communities.
