Part II—Geophysical investigations in the Hawaiian Islands

September 21, 1939

During 1938 and 1939, an extensive series of geophysical surveys, employing both resistivity and magnetic methods, have been carried on in the Hawaiian Islands by the Section of Geophysics of the United States Geological Survey in cooperation with the Division of Ground‐Water of the Survey and the Division of Hydrography of the Territorial Government (see Fig. 1). During this time, surveys have been conducted on the islands of Oahu, Molokai, and Maul. Two distinct types of ground‐water occurrence are being investigated: (1) The basal fresh‐water lens floating on underlying salt water in obedience to the Ghyben‐Herzberg principle (Fig. 2); and (2) perched ground‐water (Fig. 3) .
