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 ). sims 3 all dlc crack

WebWe investigated the bio- and photo-lability of dissolved organic matter (DOM) from the head, mixing zone, and mouth of the Pearl River estuary. At all three sites, bio- and photo-refractory dissolved organic carbon (DOC) and biorefractory chromophoric DOM (CDOM) dominated over the corresponding bio- … 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. It can be greatly influenced by land … See more The first optical investigations of CDOM took place in the Baltic Sea 20. Essentially, researchers wanted to know why the Sea’s water varied in color depending on the time and place it was observed 23. The … See more Chromophoric dissolved organic matter, or CDOM, is measured because of its value as an indicator of all the constituents floating around water bodies, regardless of their size or location. … See more Fluorescent dissolved organic matter, or fDOM, is the fraction of CDOM that fluoresces. This means that only some CDOM is fluorescent. … See more WebJun 1, 2014 · Dark aerobic microbial alteration of chromophoric DOM (CDOM) resulted in spectral slope changes opposite of those caused by … sims 3 a frame house
