WebTurbidity is an optical determination of water clarity 1. Turbid water will appear cloudy, murky, or otherwise colored, affecting the physical look of the water. Suspended solids and dissolved colored material reduce water clarity by creating an opaque, hazy or muddy appearance. ... Ocean water is usually clearer than freshwater due to the ... WebJun 10, 2015 · An unsupervised classification of the PACE synthetic hyperspectral data set, divided the global ocean waters into 15 classes, and obtained a set of fuzzy logic optical water type schemes (abbreviated as the U-OWT) that were tailored for several multispectral satellite sensors, which were highly compatible with other water classification taxonomies.
