Chlorophyll-α Content in the Surface Water Observed During the Cruise of the FUJI to Antarctica in 1974-1975

Abstract

Chlorophyll-α determinations of sea water were conducted on board the FUJI during the cruise to Antarctica. The chlorophyll-α content was 0.05-0.19mg/m^3 in the western Pacific. In the Cerebes Sea, the content became higher than that in the western Pacific. The content was 0.08-0.16mg/m^3 in the Indian Ocean. The highest chlorophyll-α value (1.71mg/m^3) of surface water was obtained at Station 44 (51°8'S, 106°52'E) in the Antarctic Ocean. Outside the pack-ice region of the Antarctic Ocean the value was relatively low, but in the pack-ice region the value was high ranging from 1.04 to 2.01mg/m^3.
