Chromophoric dom
Did you know?
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 to thousands of individual, unique organic matter molecules, which are primarily l… WebCDOM spectral properties and FDOM components may be used for studying changes in the relative molecular weight of DOM and also to discriminate between different organic matter pools, including as …
WebNov 20, 2024 · Dissolved organic carbon (DOC), chromophoric DOM (CDOM) absorption, and total dissolved amino acids (TDAAs) were measured. DOM photodegradation and transformation were indicated by the CDOM spectral slope (S 275−295) and diagenetic state by DOC-normalized yields of TDAA [TDAA (%DOC)]. WebMar 20, 2024 · The DOM fraction absorbing light at both ultraviolet (UV) and visible wavelengths is referred to as CDOM ( Coble, 2007 ). It is one of the major absorption components in the ocean, and a tracer for biogeochemical processes and oceanic circulation ( Nelson and Siegel, 2013 ).
CDOM is interchangeably known as chromophoric dissolved organic matter or colored dissolved organic matter 3. Both terms mean the same thing and cover the parameter that can be measured in aquatic environments as a product of decaying material. CDOM is largely a subset of DOM, or dissolved organic … See more Dissolved organic matter, or DOM, is the largest reservoir of organic carbon in the aquatic environment.
