REPORT ON GEOMAGNETIC TOTAL FORCE OBSERVATION IN THE FOURTH JAPANESE ANTARCTIC RESEARCH EXPEDITION
The geomagnetic total force observations along the navigation route from Japan to the Antarctic Ocean via Singapore and Cape Town were carried out using the Proton Precession Magnetometer which was used in the second (1957-58) and the third (1958-59) expeditions for the same purpose. We got nearly t...
