However, existing data are sparse and the mechanisms behind these trends remain to be determined.ģM (2010) Technical information, Empore solid phase extraction cartridges. Large lakes seem to fall on a continuum with smaller lakes and ocean water, in which water residence time (WRT) and DOC age are linearly related and DOC concentration is negatively correlated with log(WRT). No DOC or CDOM characterization or reactivity data exist for the tropical large lakes. Isotopic data for Lake Superior show that its DOM consists of carbon converted into organic matter in the previous decade, though it is difficult to resolve if this organic matter is terrestrial or autochthonous material. DOM in these three lakes contain a large proportion of reworked, terrestrially-derived organic matter. In Baikal, Superior, and Michigan, however, CDOM is the main non-water absorber of visible light. Existing data show that the five largest lakes have lower DOC and CDOM concentrations and clearer water than the global lake median. Large lakes, however, are understudied in terms of carbon cycling, including the roles of dissolved organic matter (DOM) as dissolved organic carbon (DOC), as chromophoric dissolved organic matter (CDOM), and at the compound class or molecular level. They contain > 50% of Earth’s surface liquid freshwater and 15% of Earth’s lake-water dissolved organic carbon. The world’s largest five freshwater lakes include tropical meromictic, temperate weakly stratified, and temperate holomictic lakes ranging in age from twenty-five million to ~ 10,000 years old.
