WebAbsorption of sunlight by chromophoric dissolved natural organic matter (CDOM) is environmentally significant because it controls photic zone depth and causes photochemistry that affects elemental cycling and contaminant fate. Both the optics (absorbance and fluorescence) and photochemistry of CDOM display unusual properties that cannot easily ... WebApr 20, 2024 · The light-absorbing property of chromophoric DOM (CDOM) affects ocean optics ( Blough and Del Vecchio, 2002) and leads to an array of photoreactions involved in marine biogeochemical cycles of organic carbon, nutrients, and trace gases (Mopper et …

Colored dissolved organic matter (CDOM) is the optically measurable component of dissolved organic matter in water. Also known as chromophoric dissolved organic matter, yellow substance, and gelbstoff, CDOM occurs naturally in aquatic environments and is a complex mixture of many hundreds … See more The concentration of CDOM can have a significant effect on biological activity in aquatic systems. CDOM diminishes light intensity as it penetrates water. Very high concentrations of CDOM can have a limiting effect on See more Traditional methods of measuring CDOM include UV-visible spectroscopy (absorbance) and fluorometry (fluorescence). Optical proxies have been developed to characterize sources and properties of CDOM, including specific ultraviolet … See more • The Color of the Ocean from science@NASA See more • Blackwater river • Color of water • Dissolved organic carbon (DOC) • Ocean turbidity • Secchi disk See more WebMar 20, 2014 · Rochelle-Newall E J, Fisher T R.
