Burial in sediments removes organic carbon (OC) from the short-term biosphere-atmosphere carbon (C) cycle, and therefore prevents greenhouse gas production in natural systems. Although OC burial in lakes and reservoirs is faster than in the ocean, the ma

Based on the average OC AR of 32.1 g C m−2 year−1 from the five lakes, carbon burial in lake sediments may be as much as 6.8 × 1013 g C in the MLYB over the past 100 years. 展开 关键词: OC ARs Subtropical and shallow lakes Carbon storage Eutrophication ...
Synonyms Carbon biodegradation; Carbon remineralization Definition Organic carbon ( OC ). In geochemistry, carbon that occurs in materials of ultimately biological origin and that can be oxidized. Organic matter (OM) is the material that contains organic carbon (OC). Degradation . Transformations of ...
. Globally, the 95% confidence interval for the annual burial rate is 26.1 (+6.3; −5.1) Tg OC. This equates to a burial fraction that is 42% larger than that of the most recent mangrove carbon budget (2008), and represents 10–15% of estimated annual mangrove production. This ...

Lakes are a central component of the carbon cycle, both mineralizing terrestrially derived organic matter and storing substantial amounts of organic carbon (OC) in their sediments. However, the rates and controls on OC burial by lakes remain uncertain, as do the possible effects of future global...

Black carbon (BC) is a recalcitrant form of organic carbon (OC) produced by landscape fires. BC is an important component of the global carbon cycle because, compared to unburned biogenic OC, it is selectively conserved in terrestrial and oceanic pools.
