Magnetic work of the United States Coast and Geodetic Survey From July 1, 1946 to June 30, 1947

Abstract

The close cooperation maintained in former years with the Department of Terrestrial Magnetism of the Carnegie Institution of Washington was continued by temporary loans of certain instruments and by exchange of data. A regular repeat field party was in operation in central and northern Alaska. As usual, a number of observations of magnetic declination were made by parties of the Survey which were not engaged primarily in magnetic work. These included observations made at several airports in the United States, and in connection with hydrographic surveys along the coasts of tho United States and Alaska.

Magnetic work of the United States Coast and Geodetic Survey from July 1, 1947 to June 30, 1949

“…The collaboration of Survey personnel is reflected in various committee reports and other documents of the International Association of Terrestrial Magnetism and Electricity [HARRADON 1950;KNAPP, 1950a;McCOMB, 1950;ROBERTS, 1950a and b] and of the Commission on Cartog-" raphy, Pan American Institute of Geography and History [ANONYMOUS, 1949], and in several art icles in print or in press [ADAMS, 1949;HOWE, 1948, p. 228;KNAPP, 1950b;MOODY, 1949;ROBERTS, 1948a, b, and,…”

“…This report is one of a series, of which the antecedent appeared two years ago [ROBERTS, 1948a]. During the subsequent interval, geomagnetic observing programs have attained new levels of interest and significance as a result of postwar technical and commercial developments in avi ation, in exploration geophysics, and in radio techniques.…”
