Long-Term Ecological Research (LTER)/HBR004: Hubbard Brook Soil Temperature, Snow, and FrostEntry ID: LTER_HBR004
Abstract: LTER - Long-Term Ecological Research Program/Hubbard Brook
Experimental Forest (HBEF).
Soil temperature data have been collected approximately weekly at one
location in the Hubbard Brook Experimental Forest (HBEF) since 1959.
Sensors are replicated (1 and 2) at depths of 1, 3, 6, 9, 12, 18, 24,
and 36 inches. The sensors are Colman temperature-moisture units.
Snow course data have ... been collected approximately weekly at a network
of standard rain gauges at the HBEF from 1956 to the present when
there was snow on the ground. Each measurement for the snow data
consists of the average of 10 points measuring snow depth and water
content using a Mt. Roses snow tube. The presence or absence of frost
in the ground is checked at two points adjacent to each snow course by
probing with a ski pole. The percentage of total probe locations
having frost is recorded for each snow course. At the first two snow
points having frost, a hole is dug into the soil and the depth of
frost is measured. The two depths are averaged.
The Hubbard Brook Experimental Forest (HBEF) is a 3,160 hectare
reserve dedicated to the long-term study of forest and stream
ecosystems. Located in the White Mountain National Forest of New
Hampshire, the HBEF was established in 1955 and is operated by the
USDA Forest Service, Northeastern Forest Experiment Station.
