Rendering of the water column gas plume (white dots) that guided the Seascape Alaska 3 dive at the Sanak seeps, , showing the bottom part of gas flares that can be imaged to 1,500 meters (4,920 feet) above the seafloor. Bathymetry is contoured at 10 meters (33 feet), and colors show slope in degrees, with red being steep angles. This view looks east along the line of seeps, and the total width of the seeping area is about 600 meters (1,950 feet). The Aleutian trench is towards the right.
