The Bear Brook Watershed in Maine (BBWM) is in its third decade of research on the response of these northern forested ecosystems to a changing chemical and physical climate. The emphasis of research has been, and continues to be, on decadal scale responses to whole ecosystem acidification, nitrogen enrichment, and climatic drivers as evident in events ranging from instantaneous episodic responses in
ecosystem processes to decadal scale trends.
Scientific questions have emphasized:
Several major initiatives are currently underway focusing on understanding nitrogen dynamics over the decadal-scale arc of ambient and experimental conditions, including the importance of an altered ecological stoichiometry between carbon, nitrogen, and phosphorus. This includes the use of stable isotope techniques and studies of soil and dissolved organic carbon composition and behavior.
This page offers a short description of the scope of BBWM science as this new version of the BBWM web site is launched at the beginning of 2012. Check back soon for updates.
