Passive Road over Perennial Ice at Casey Station, Antarctica
(American Society of Civil Engineers, 2014)Resupply of Australia’s Antarctic station Casey relies on the movement of heavy cargo over land from the wharf to the station. The road consists of gravel that is deposited seasonally over 2–3 m of perennial ice. However, ... -
Extraction of Sea Ice Thickness Using a Laser Rangefinder Mounted on an Icebreaker
(American Society of Civil Engineers, 2013)Recently, higher sea surface temperature and less sea ice extents have been reported because the polar environments are dramatically transforming because of climate change. Measurements of sea ice thickness are important ... -
Automatic Controls for the Carbon Fiber Tape-Based Deicing Technology
(American Society of Civil Engineers, 2014)Snow and ice on roads are hazardous. Many methods are applied for road surface deicing. Most of these methods, however, suffer from one or more of the following shortcomings: low energy efficiency, large labor requirements, ... -
Review of Effectiveness and Costs of Strategies to Improve Roadbed Stability in Permafrost Regions
(American Society of Civil Engineers, 2013)This paper reviews the effectiveness and costs of strategies to improve roadbed stability in permafrost regions, based on a synthesis of literature findings. Roadbeds in permafrost regions experience instability when the ... -
Use of Stabilized Stream-Monitoring Sections to Monitor Annual Streamflow on the Alberta Boreal Plain
(American Society of Civil Engineers, 2013)Streamflow in small forested watersheds on the Boreal Plain of western Canada can be a challenge to monitor due to high variation in flow, shifting channel morphology, aufeis obstructions, shallow channel depth, and debris ... -
Mathematical Model of Cryospheric Response to Climate Changes
(American Society of Civil Engineers, 2013)This paper focuses on the development of simplified mathematical models of the cryosphere which may be useful in further understanding possible global climate change impacts and in further assessing future impacts captured ... -
Uniaxial Compression Tests on Diesel-Contaminated Frozen Silty-Soil Specimens
(American Society of Civil Engineers, 2013)Contamination of permafrost by hydrocarbons is an important issue in northern regions. In addition to harmful environmental impacts, diesel-fuel spills in permafrost associated with vehicle-storage areas, storage tanks, ... -
Open-Pit Glacier Ice Excavation: Brief Review
(American Society of Civil Engineers, 2013)The authors have compiled information on the fundamentals of open-pit glacier ice excavation from a variety of sources. These sources primarily include U.S. Army technical and scientific studies and peer-reviewed research ... -
Behavior of CFRP-Prestressed Concrete Beams under Sustained Load at Low Temperature
(American Society of Civil Engineers, 2013)The behavior of precast concrete beams prestressed using carbon fiber-reinforced polymer (CFRP) rods was studied under the combined effects of sustained load and low temperature. Three 13-year-old concrete T-beams were ... -
Effects of Freeze-Thaw Cycles and Seawater Corrosion on the Behavior of Reinforced Air-Entrained Concrete Beams with Persistent Loads
(American Society of Civil Engineers, 2013)The effects of freeze-thaw cycles and seawater corrosion on the material properties of air-entrained concrete specimens and structural behavior of reinforced air-entrained concrete beams under persistent loads were ... -
Formulation and Characterization of Freezing Saturated Soils
(American Society of Civil Engineers, 2013)The writers have derived a unified governing equation for freezing saturated soils. This equation considers the governing mechanisms with respect to individual thermal and hydraulic fields. The writers included coupling ... -
Proof of Concept: Firn Air Facility Cooling at Summit Station, Greenland
(American Society of Civil Engineers, 2013)A firn air cooling system that utilized the natural reservoir of cool air at depth in polar ice sheets was tested at Summit Station, Greenland during the summer of 2010. Cooling is required on station to meet the requirements ... -

Modeling Cold Region Ground Temperatures with a Heat Flux Upper Boundary Model
(American Society of Civil Engineers, 2013)This study formulates a heat flux boundary model to assess cold region ground temperatures and to distinguish the difference between this boundary type and a temperature boundary type. This formulation considers the impacts ... -
Vibration Reduction of Bucket Foundation Platform with Fixed Ice-Breaking Cone in the Bohai Sea
(American Society of Civil Engineers, 2012)The bucket foundation platform is an important engineering design alternative in oil/gas field developments in the Bohai Sea because of its economic and structural characteristics. Severe ice-induced vibrations were observed ... -
Holistic Approach to Decision Making in the Formulation and Selection of Anti-Icing Products
(American Society of Civil Engineers, 2012)To effectively fight snow storms in the challenging funding environment, many maintenance agencies in North America have started to produce their own anti-icing liquids, instead of procuring commercial anti-icers. This ... -
Investigation of the Stress–Strain and Strength Behaviors of Ice Containing Methane Hydrate
(American Society of Civil Engineers, 2012)Mechanical properties and deformation behaviors of methane hydrate are important to assess the stability of gas hydrate reservoirs. In this study, using a high-pressure and low-temperature triaxial testing apparatus, the ... -
Low-Energy House in Arctic Climate: Five Years of Experience
(American Society of Civil Engineers, 2012)The aim of this article is to present and discuss the experience gained from a low-energy house in Sisimiut, Greenland, over the 5 years of operation since its inauguration in April 2005. The house was designed to test and ... -
