Some Notes on Water Color in Keweenaw Bay (Lake Superior)
Journal of Great Lakes Research, 2004Spectral subsurface irradiance reflectance—intrinsic water color—was derived from above-water radiance measurements using a hand-held spectroradiometer along a transect on Keweenaw Bay, Lake Superior. The reflectance spectra were typical of oligotrophic lacustrine waters. The reflectance peak wavelength shifted from 484 nm at stations farthest offshore

Effect of Dispersion on the Coloring Properties of Aluminum Dye Lakes
Journal of Pharmaceutical Sciences, 1988The effect of particle size on the coloring properties of aluminum dye lakes was studied. Lakes impart color by dispersion in the medium to be colored. Dispersion techniques were developed, using scanning electron micrographs for particle sizing. The color strength and the trichromatic colorimetric properties were calculated from reflectance values ...

Color pattern variation in Lake Erie water snakes: inheritance
Canadian Journal of Zoology, 1993The hypothesis that color pattern variation in Lake Erie island water snake (Nerodia sipedon) populations results from the opposing effects of natural selection and gene flow requires that this variation have a genetic basis. To determine whether color pattern variation is genetically based, data on the color pattern of wild-caught females and their ...

Aluminium based dye lakes from plant extracts for textile coloration
Dyes and Pigments, 2012Abstract Production of concentrated natural dyes is a pre-requisite for a re-introduction of plant colorant based dyes into modern textile dyeing operations. Aluminium salts such as Al 2 (SO 4 ) 3 .14-15H 2 O or KAl(SO 4 ) 2 .12H 2 O can be used to precipitate extracted plant dyes from aqueous extracts at pH 5.0–5.5.
