REPORT ON SEA ICE OBSERVATIONS OF THE JAPANESE ANTARCTIC RESEARCH EXPEDITION IV, 1959-60 WITH THE "SOYA"
Introduction Since m/s "SOYA" had reached the ice edge on Dec. 27, 1959 at 65°15'S, 48°35'E, the officers on watch carried out continuous visual ice observations, under the supervision of the navigating officer, until the ship left the ice off Riiser-Larsen Peninsula on Feb. 21,...
