Dissolved organic carbon (doc) in stream water at watersheds 7, 14, and 27 at the Coweeta Hydrologic Laboratory, Otto, North Carolina, USA.

Dissolved organic carbon (DOC) plays a critical role in stream ecosystem processes. This study seeks to examine long-term patterns in DOC concentration in stream water resulting from climatic variation and associated with recovery form clear-cutting. Watershed 7 was clear-cut in 1977 as part of a multi-investigator study examining the response of both the terrestrial and aquatic communities to commercial clear-cutting.
