Summary:

The BOREAS TE-12 team collected shoot geometry data in 1993 and 1994 from Aspen, Jack Pine, and Black Spruce trees. Collections were made at the Southern Study Area FEN, YJP, OJP, OA, YA, MIX and OBS sites. A caliper was used to measure shoot and needle lengths and widths. A volume displacement procedure was used to measure the weight of the shoot or twig submerged in water.

A guide document which includes more information about this data set can be found at https://daac.ornl.gov/data/boreas/TE/te12sgd/comp/TE12_ShootGeom.txt.

ORNL DAAC maintains information on the entire BOREAS Project.
