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

Alternate Identifier:

DOI PLACE HOLDER

Abstract:

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).

Previous versions of this dataset included both temperature and moisture. These data are now available as temperature (this dataset) and moisture (https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-hbr&identifier=137).

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.

LOCATION DESCRIPTION

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).

DATA DESCRIPTION

In each plot, we installed two replicate Decagon soil moisture and temperature probes (Model 5TM) to 5 cm depth. The temperature range is from -40 to 50 oC, with a resolution of 0.1 oC and an accuracy of 1 oC. Measurements were recorded hourly with a Decagon EM50 datalogger (14 extensive plots) or Campbell Scientific datalogger (6 intensive plots) until September 2012, after which all 14 continuously monitored plots were configured with Decagon EM50 dataloggers. Outliers were excluded using an algorithm that performed a range check and evaluated extreme deviations from the other sensors. We used an ensemble regression approach to then fill gaps in the data by regressing the probe in question against all 27 other probes and calculating the median prediction for a missing value.
