Cold Regions Research and Engineering Laboratory

CRREL arose from a consolidation of three antecedent organizations whose purpose was to understand frozen ground, permafrost, snow and ice as factors which were important in strategic northern areas during the Cold War.

In its first 25 years CRREL researchers contributed to the understanding of polar ice caps, permafrost, and the engineering technology for developing natural resources in cold climates, such as Alaska.

More recently, CRREL researchers have made contributions to science in climate change, the understanding of wave propagation for sensor systems, the control of snow on structures and ice in navigable waterways, and the environmental remediation of military installations.

"[2] The technical areas that CRREL staff reportedly engage in are:[3] The main facility is located in Hanover, New Hampshire, north of Dartmouth College.

[13] CRREL was formed on 1 February 1961 from a merger of the earlier Snow, Ice and Permafrost Research Establishment (SIPRE)[16] with the Arctic Construction and Frost Effects Laboratory (ACFEL).

During its first quarter century, CRREL researchers and staff were active in the Arctic, Antarctica, Alaska and the Great Lakes, providing climatic history data, addressing resource extraction issues and extending winter navigation.

CRREL staff members participated in the exploration of two transportation options, the use of an ice-breaking oil tanker, and the use of an over-land pipeline that would cross much of Alaska over regions of permafrost.

[19] CRREL researchers were active participants in both voyages of the icebreaking oil tanker SS Manhattan to assess the feasibility of the sea transport option.

[17][21] CRREL played a role in assisting the U.S. Air Force to establish[22] and maintain a system of Distant Early Warning (DEW) Line facilities during the Cold War era.

[26] CRREL continued to grow its capability to serve the U.S. military with programs in signal propagation that would facilitate the detection of enemy movements via infrared imaging, radar,[27] acoustics[28] or seismic[29] sensors in any meteorological conditions.

It served the environmental needs of the U.S. Army by facilitating the identification and clean-up of contaminants on training lands, due primarily to partially detonated explosives[30] or unexploded ordnance (UXO).

[39][40] In 2016, CRREL research civil engineers designed, built and tested a new snow runway for the McMurdo Station, called "Phoenix".

[41] In its Corps of Engineers Civil Works mission, CRREL researchers developed innovative ways to avoid ice jams and databases to address the widespread occurrence of such problems.

[44] In building technology, researchers helped develop statistical means to identify snow and icing loads throughout the United States[45] and standards for measuring heat loss,[46][47] roof moisture detection,[48] and frost-protected shallow foundations.

After the 1990 discovery of TCE in groundwater, CRREL embarked on a remediation plan, approved by the New Hampshire Department of Environmental Services (NHDES), with assistance from the U.S. Army Toxic and Hazardous Materials Agency and the Corps of Engineers New England Division.
