Nutrient matters in the Indian sector of the Antarctic Ocean
During the cruise of the R. V. KAIYO MARU (Fisheries Agency of Japan) in the Indian Sector of the Antarctic Ocean from December 1979 to March 1980,the surface observation between Australia and Antarctica and serial observation in the area bounded by 100°-120°E and 61°-65°S off the Budd Coast of Wilk...
