Abstract
The retarding effect of the war on the progress of geophysical research, indicated in last year's summary, continued to influence progress in geomagnetic and geoelectric research during July 1, 1942, to June 30, 1943. Difficulties of communication between countries have increased and scientific investigations have been largely turned toward developments more nearly connected with the requirements of modern warfare. Many established organizations and observatories, however, have found it possible to maintain at least part, if not all, of their programs so that the loss of continuity in accumulating data is not too serious. The war has, unfortunately, prevented the proposed cruises of the British Admiralty magnetic‐survey vessel Research and the resulting loss of additional observations over the oceans to determine those important changes with the years in the geomagnetic elements is most serious—the more so because of their need in maintaining isomagnetic charts so vital for purposes of navigation, and application in defensive and offensive operations.
