“…(0-1 g at 10 c/s, 1-0 g at 100 c/s). Surface vehicles and cargo ships generate frequencies lower than 15 c/s, but with amplitudes of several inches (Dummer and Griffin, 1962).. Natural rubber anti-vibration mountings are unsuitable for the lowest temperatures, and coil spring devices on the same mechanical principles are available under the name "Equiflex". Silicone rubbers which retain their elasticity at a temperature of -75° C. or below are available in various extrusions and sheet thick-nesses.…”

The increasing use of electronic techniques in making measurements in all branches of science has been evident for many years in laboratories, and we must expect the same trend at scientific stations and in field operations in the polar regions. The aim of this and a later article is to provide information about polar conditions for those already familiar with electronic methods in the laboratory, and to call attention to the variation in properties and reliability of components for which allowance should be made in specification and design of electronic apparatus.
