Summary

Soil frost measurements have been made at Sleepers River Research Watershed starting in 1983. Measurements were made by U.S. Army Corps of Engineers Cold Regions Research and Engineering Laboratory from 1983 to 1993, followed by the U.S. Geological Survey from 1993 to the present. Measurements started at 5 sites and has increased to 10 sites. Sites range in elevation from 225 to 670 meters and are in a mix of field and forest types. Soil frost measurements are made with tubes filled with methylene blue solution; on freezing, the methylene blue remains in the liquid phase, yielding clear ice that marks the depth of soil frost (Ricard and others, 1976). Soil frost measurements typically are made 2 to 4 times a month between November [...]

Purpose

A long-term record of soil frost is being collected to evaluate trends in frost depth and duration. Of particular interest are the effects of changing climate on soil frost. Paradoxically, a warming climate may increase the depth and duration of soil frost if it reduces the depth and duration of the insulating snow pack (Brown and DeGaetano, 2011), though model results do not back up this notion (Campbell and others, 2010). Frozen soil affects infiltration and recharge and thus has wide ranging impacts on streamflow, erosion, groundwater levels, and soil moisture (Shanley and Chalmers, 1999; Hardy and others, 2001). Increases in soil frost depth can damage or kill roots and fauna in the biologically active soil zone.
