Hubbard Brook Experimental Forest: microbial biomass and activity at Climate Change Across Seasons Experiment (CCASE) plots, 2015

This data set includes measurements of microbial biomass and activity
measured on the Climate Change Across Seasons Experiment (CCASE) plots
in May 2015. Reference (or control) plots are shared with the
collaborating Northern Forest DroughtNet experiment. There are six
plots total (each 11 x 14m). Two are warmed 5 degrees C throughout the
growing season (Plots 3 and 4). Two others are warmed 5 degrees C in
the growing season and have snow removed during winter to induce soil
freeze/thaw cycles (Plots 5 and 6). Four kilometers (2.5 mi) of
heating cable are buried in the soil to warm these four plots. Two
additional plots serve as controls for our experiment (Plots 1 and 2).
This data set includes measurements of microbial biomass and activity. These data were gathered as part of the Hubbard Brook Ecosystem Study
(HBES). The HBES is a collaborative effort at the Hubbard Brook
Experimental Forest, which is operated and maintained by the USDA
Forest Service, Northern Research Station.
