The status and stability of permafrost carbon on the Tibetan Plateau
Permafrost regions at high latitudes and altitudes store about half of the Earth's soil organic
carbon (SOC). These areas are also some of the most intensely affected by anthropogenic …

Reevaluating the role of organic matter sources for coastal eutrophication, oligotrophication, and ecosystem health
A Deininger, H Frigstad - Frontiers in Marine Science, 2019 - frontiersin.org
Organic matter (OM) in aquatic systems is either produced internally (autochthonous OM) or
delivered from the terrestrial environment (ter-OM). For eutrophication (or the reverse …
