Soil moisture and temperature along an elevation gradient at the Hubbard Brook Experimental Forest, 2010 - present.

Soil temperature and soil moisture have been measured
at multiple locations at the Hubbard Brook Experimental
Forest (HBEF), as part of a study of the relationships
between snow depth, soil freezing and nutrient cycling
(http://www.ecostudies.org/people_sci_groffman_snow_summary.html). 
In October 2010, we established 6, 20 x 20-m plots (intensive
plots) and 14 10 x 10-m plots (extensive plots) along an
elevation gradient, with eight of the plots on north-facing
slopes and twelve on south-facing slopes. Soil temperature
and soil moisture were measured at hourly intervals on these
plots beginning in November 2010. Six locations were
discontinued in September 2012 (E04, E05, E06, E11-B, E13,
and E14). 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.
