Climate Change Across Seasons Experiment (CCASE) Sapling Study at the Hubbard Brook Experimental Forest: Soil and Air Temperature

Soil temperature was measured on all Climate Change
Across Seasons Experiment (CCASE) sapling treatment plots.
There were seven treatments for each species of maple. For
each species, ten saplings experienced ambient temperatures
(reference), ten experienced growing season warming with no
induced freeze-thaw cycles in winter (warmed), ten in each of
four groups experienced warming in the growing season coupled
with two, four, six, or eight soil freeze-thaw cycles in
winter (warmed + 2 FTC, warmed + 4 FTC, warmed + 6 FTC,
warmed + 8 FTC), and ten experienced snow removal in winter
with ambient temperatures in the growing-season (snow
removal). 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.
