Figueroa-Sandoval, B. ., . Flores-Magdaleno, . Dissolved organic matter (DOM) is an important property of lake ecosystems, resulting from the decomposition of organic matter stored in soils and of plankton in the water column. Colored dissolved organic matter (CDOM), the fraction that absorbs ultraviolet (UV) and visible light, is the controlling factor for the optical properties of many surface waters. Little is known about the mechanisms by which DOM and CDOM evolve in lakes formed during glacial retreat. As part of a larger study of the ecosystems in glacial lakes, the present project examined the quality of DOM and CDOM in lakes in SW Greenland. Nine lakes in . Managing by Network.
