Chromophoric organic matter

WebAug 1, 2024 · Dissolved organic matter (DOM) is the largest dynamic pool of organic carbon in both marine and freshwater ecosystems. It is quantified as the concentration of dissolved organic carbon (DOC) (Benner, 2002; Cole et al., 2007 ). WebChromophoric dissolved organic matter (CDOM) is a ubiquitous component of the open ocean dissolved matter pool, and is important owing to its influence on the optical properties of the water column, its role in photochemistry and photobiology, and its utility as a tracer of deep ocean biogeochemical processes and circulation.
