The percentage of visible light P (in decimal form) at a depth of x meters for Long Island Sound can be approximated by P = e − 0.5 x . a. Determine the depth at which the light intensity is half the value from the surface. Round to the nearest hundredth of a meter. Based on your answer, would you say that Long Island Sound is murky or clear water? b. Determine the euphotic depth for Long Island Sound. That is, find the depth at which the light intensity falls below 1 % . Round to the nearest tenth of a meter.
