When mobility in northern regions is being considered, the need for a means to assess ice-covered water crossings becomes evident. There are two major aspects to this problem: determination of the crossing profile (from which one obtains ice thickness, support characteristics, and crack locations), and determination of the bearing capacity of the crossing. This paper discusses instrumentation developed through the U.S. Army Cold Regions Research and Engineering Laboratory to remotely measure the ice thickness and its relationship to the water body, the banks, and other ice forms. It further references applicable work done on the bearing capacity of ice sheets, and comments on the problems associated with the determination of ice strength. (Author)
