Abstract

A model of the subsurface irradiance distribution that is based on the two-flow equations and allows for variations of the concentrations of various water quality constituents with depth has been described by Bostater, Ma, and McNally. This model allows output of the irradiance spectra at various depths. By combining the two-flow model with the hydrodynamic model of Blumberg and Mellor, the effect of the absorption of irradiance as a function of wavelength and depth on water temperature, density, turbulent kinetic energy, pressure, and the resulting circulation in an idealized ocean basin is studied. The two-flow model is set up to allow variation of the water quality parameters to occur in three layers, any number of layers, or to be constant with depth and thus affect the absorption of the sun's energy. Three simulations were run using (a) clear water coefficients, (b) a vertical distribution of chlorophyll, and (c) a vertical distribution of suspended sediments. For comparison, coefficients and attenuation for various water types included in the Princeton Ocean Model were used for comparison.
