New England Field Sites

 

New England field sites

We are actively involved at three research sites in New England.

 

Taken together, these sites form a 400 km long transect running from southwest to northeast and spanning the major forest types of the region: A. Howland Forest, Maine: boreal transition (spruce-fir, Picea-Abies) B. Bartlett Experimental Forest, New Hampshire (and the nearby Hubbard Brook LTER): northern hardwood (maple-beech-birch, Acer-Fagus-Betula) C. Harvard Forest, Massachusetts: transition hardwood (oak-hickory, Quercus-Carya)

 

Eddy covariance measurements of surface-atmosphere exchanges of carbon, water and energy (along with extensive ancillary ecological data, and full meteorological and radiometric data) have been made at Howland Forest since 1996 (PI David Hollinger, USDA Forest Service) and Harvard Forest since 1991 (PIs Bill Munger and Steven Wofsy, Harvard EPS). The Richardson lab is now in its ninth year (since 2004) of conducting CO2 flux measurements at Bartlett. Beginning in spring 2010, we are making eddy covariance measurements of CH4 fluxes at Howland with a new Picarro cavity ring down spectrometer.

 

All three sites are part of the AmeriFlux network and contribute data to FLUXNET; both Harvard Forest and Bartlett Experimental Forest have been selected as NEON sites.

 

Our data from Bartlett are available for download from the AmeriFlux data portal, subject to a standard “Fair Use” Policy.
