US Army Cold Regions Research & Engineering Lab
Hanover, New Hampshire
Supporting Stations: McMurdo Station
There are several objectives for the T-940 activities during the 2011-2012 season. Projects include engineering and basic research in support of the South Pole Traverse (SPoT), Single Airfield Complex (SAC), Snow Roads and Transportation Evaluation (SR&T), South Pole Station Operations (SPSO), and a McMurdo Drainage and Sediment Transport study (D&ST). More-specific objectives for these projects are listed below. SPoT: 1. Use imagery analysis, ground penetrating radar (GPR), and physical characterization to assess route safety in areas where crevasses may be present; 2. Test prototype cargo sled; 3. Continued tests for sled performance and mobility improvements. SAC: 1. Understand the effects and possible remedies of some natural occurrences that are potential long-term problems for the SAC; 2. Understand how operation and maintenance of runway/skiway correlates with seasonal conditions and performance of the airfields. SR&T: 1. Document current practices for snow road and continue monitoring program for road condition, maintenance, and use; 2. Transfer "better practices" information to support contractor road crews and work with them to employ new practices; 3. Site characterization of the road “transition” area for topographic, weather, seismic, and geophysical surveys; 4. Assess effects of tracked/wheeled lane switching; 5. Study effects of snow miller on road conditions. SPSO: 1. Work with the NSF and Cold-Regions Research and Engineering Laboratory (CRREL) contractor on specified South Pole operations issues. D&ST: 1. Transfer testing and data collection practices to support contractor personnel; 2. Work with support contractor through the season to assess data collection; 3. Analyze data collected.
