Forskning för längre skidsäsong

Norrbottens Kuriren (Gällivare, Kuriren, Sweden); November 10, 2000 

Ett 3—5-ärigt forsknigsproject med primärt mål att förlänga längdsskidåknings-säsongen i Gällivare pågår vid Dundrets skidstadium.  Ursprungsmetoden är hämtad från Alaska och går ut på att leda bort värme ur marken.  — Man kan saga att vi försöker skapa ett slags permafrost på konstgjord väg, berättar doktoranden Anna Forsström från Luleå tekniska universitet.

Scientists Aim to Freeze Chena Hot Springs Ground 

Fairbanks Daily News-Miner (AK); September 8, 1998

Scientists have decided it’s time to freeze that asphalt-buckling villain permafrost in its tracks.

At a test site on Chena Hot Springs Road, construction crews are installing grids of carbon dioxide-filled steel pipes – called thermosyphons – engineered to carry away heat from below the road’s surface.  The intent is to freeze the permafrost permanently.

Waste Treatment Technology News; April 1998

A foundation-shoring technique has led to a waste containment technology.  Arctic Foundations, Inc. (5621 Arctic Blvd., Anchorage, AK 99518; Tel:  907/562-2741, Fax: 907/562-0153) has pioneered a ground-freezing process it calls a “cryogenic barrier.”  Originally developed to prevent foundation slumping after seasonal freeze/thaw cycles in the Alaskan tundra, the company was approached by the Department of Energy (DOE) to undertake a project freezing soils surrounding a contaminated pond at Oak Ridge National Laboratory (ORNL).  The 316,000-gallon pond, which formerly stored nuclear reactor cooling water, contains large amounts of cesium-137 and strontium-90.

TRADE LINE - A Publication of World Trade Center Alaska; Summer 1998

Another member of World Trade Center Alaska making inroads into the world market with their products is Erwin L. (Erv) Long, P.E., President of Arctic Foundations, Inc.  Arctic Foundations does exactly what their name indicates; they build specialty foundation components for structures in Arctic environments.  The structures could be buildings, bridges, and docks or pipeline supports.  Each design is different because, across the Arctic, conditions change.  Arctic Foundations is looking at Russia as a market because “they have more permafrost than we do in Alaska but still, the problems are very similar.”

The Oak Ridger (TN); Section: State News; November 21, 1997

Ed Yarmak cannot be bothered by the cold. He gives it away by wearing a flowered Hawaiian shirt on what most in East Tennessee would consider a blustery November day. In Yarmak's business, cold is good.

A registered civil engineer, he freezes the ground for a living. He might have never imagined it, but the Department of Energy wanted to use his company's expertise in the more temperate climate of Oak Ridge.
