Diavik Diamond Mine This is the largest diamond ever found in North America. Diavik Diamond Mine The Diavik Diamond Mine is a diamond mine in the North Slave Region of the Northwest Territories, Canada, about northeast of Yellowknife. Diavik Diamond Mine is an industrial complex set in a remote, sub-Arctic landscape. It consists of four kimberlite pipes associated with the Lac de Gras kimberlite field and is located on an island in Lac de Gras and is informally called East Island. It is about south of the Arctic Circle. In the 2015 satellite image below, one can see the two main open pits,
Permafrost carbon cycle to the atmosphere. Carbon stored within arctic soils and permafrost is susceptible to release due to several different mechanisms. Carbon that is stored in permafrost is released back into the atmosphere as either carbon dioxide (CO) or methane (CH). Aerobic respiration releases carbon dioxide, while anaerobic respiration releases methane. Carbon is continually cycling between soils, vegetation, and the atmosphere. Currently, carbon flux from permafrost soils is minimal, however studies suggest that future warming and permafrost degradation will increase the CO flux from the soils. Thaw deepens the active layer, exposing old carbon that has been in storage for decades, to
