gelbstoff

Example Sentences

• "The problem of the Gelbstoff in the sea"
• "Like soil humus and humic materials indigenous to freshwaters, seawater gelbstoff absorbs light strongly into the ultraviolet region of the spectrum: Sieburth and Jensen (1968) noted a peak at 263 nm."
• "[page 63] Kalle concluded that dissolved yellow substances contribute substantially to any deviation from the blue colour of pure water into the longer wavelengths region of the visible spectrum. […] Chemically the material defied unequivocal characterization, a situation which has remained essentially unchanged. Thus, for want of a systematic designation Kalle called the material "Gelbstoff", the German word for "yellow material". […] Marine Gelbstoff is a material formed in the sea with certain spectral characteristics. It is not derived from terrestrial sources and appears to be composed of fulvic and humic components both of which are structrally different from their terrestrial counterparts. […] [page 67] These are more indications of an autochthonous origin of marine Gelbstoff supported by the interesting observation that Gelbstoff from a bog water precipitated within a week at room temperature when an equal amount of seawater was added to its solution."
• "Light is absorbed in water by four components: water itself, dissolved yellow substances (gelbstoff), phytoplankton, and tripton (inanimate particulate material)."
• "[page 63] Kalle concluded that dissolved yellow substances contribute substantially to any deviation from the blue colour of pure water into the longer wavelengths region of the visible spectrum. […] Chemically the material defied unequivocal characterization, a situation which has remained essentially unchanged. Thus, for want of a systematic designation Kalle called the material "Gelbstoff", the German word for "yellow material".
