The bidirectional reflectance of oceanic waters is conveniently described in a normalized way by forming the ratio of the upwelling irradiance Eu to any upwelling radiance Lu(θ′, φ). This ratio, Q[θ′, θ0, (φ0 - φ)], where θ′, φ are the nadir and azimuth angles for the upward radiance and θ0, φ0 are the zenith and azimuth angles of the Sun, has been determined from measurements at sea and computed via Monte Carlo simulations using the inherent optical properties measured in the field and appropriate boundary conditions (clear sky, no wind, varying Sun angle). Experimental and computed Q values are in excellent agreement. -from Authors
