Some of the geophysical research being conducted by the Air Force Cambridge Research Center, Air Research and Development Command, was described in an earlier issue (Physics Today, p. 10, February 1953). It may be recalled that the Terrestrial Sciences Laboratory investigated the properties and interactive effects of the land, oceans, and atmosphere using techniques and instrumentation of seismology and acoustics. The occupation of Ice Island T‐3 in the Arctic research program was given as an example of the interrelationship of terrestrial and atmospheric studies. Microseismic activity was correlated with meteorological conditions and the anomalous propagation of sound was described as a tool in the determination of temperatures and winds at high altitudes.
