Further investigations were carried out on board a wooden ship (18.46 ton, 60 H.P.) in June, 1963. Results are as follows : (1) Magnetic attraction was perceived in the bay throughout the vicinity of the entrance, the maximum value amounting to 2.7°. The deviation of obtained values was inferred to be about ±0.2°. (2) The magnetic attraction was more marked along the coast of the Satsuma Peninsula than along the opposite coast, i.e. off the Osumi Peninsula. In the north and south direction, the magnitude of attraction increased progressively towards north. The attraction was generally directed westerly, with an exception that a less marked, easterly attraction was observed in the neighbourhood of the Nagasaki-Bana Point located at the head of the Satsuma Peninsula. (3) The last-mensioned exceptional case is presumably due to a stretch of iron-sand deposits near the place in question. A comparatively marked, westerly attraction occurred off the north coast of the Osumi Peninsula. This apparently is an influence from ironsand deposits strctching near Nejime-Cho. (4) The distribution of horizontal and vertical forces of terrestrial magnetism was measured on the both peninsulas near the bay entrance. The distribution corroborates the presence of local attraction in the mouth region of the bay.}, pages = {158--169}, title = {鹿児島湾における地方磁気に関する研究I : 湾口における地方磁気の存在について}, volume = {12}, year = {} }
