The average chemical compositions of the continental crust and the oceanic crust (represented by MORB), normalized to primitive mantle values and plotted as functions of the apparent bulk partition coefficient of each element, form surprisingly simple, complementary concentration patterns. In the continental crust, the maximum concentrations are on the order of 50 to 100 times the primitive-man...

For the retrieval of chlorophyll concentrations or the total absorption coefficients of oceanic waters based on water color, there are algorithms that use either band ratios or spectral curvatures of remote-sensing reflectance or water leaving radiance. We show that band-ratio algorithms have the potential to be applied to a wider dynamic range of oceanic waters, whereas spectral-curvature algo...

We propose a novel Variational Wave Acquisition Stereo System (VWASS) that exploits new stereo reconstruction techniques for accurate estimates of the space-time dynamics of oceanic sea states. The rich information content of the acquired three-dimensional video data is exploited for predictions of directional spectra and large waves over an area by means of the Euler Characteristics of random ...
