Modeled hyperspectral reflectance signatures just above the water surface are obtained from an analytical-based, iterative radiative transport model applicable to shallow water types. Light transport within the water body is simulated using a fast, accurate radiative transfer model that calculates the light distribution in any layered media. A realistic water surface is synthesized using empirically-based spectral models of the ocean surface to generate water surface waves. Images are displayed as 24 bit RGB images of the water surface using selected channels from a synthetic hyperspectral image cube. The selected channels are centered at 490, 530 and 676 nm. Hyperspectral image cubes with two horizontal spatial dimensions and a third spectral dimension are shown to allow the detection of optically unresolved features in the two-dimensional RGB image.
