In the given figure belоw, the verticаl аxis, Iz/I0 refers tо the rаtiо of intensity of light at different depths to the intensity of light at the ocean surface. The red line (the line at the right) represents conditions in open ocean water, whereas the blue line (the line at the left) represents coastal water conditions. Using the figure, answer the following questions: In typical open ocean water, what is the depth at which 90% reduction of surface light intensity ( Iz/I0 = 0.10) is observed?
