Chlorophyll α content in the Indian sector of the Antarctic Ocean
Measurement of chlorophyll a in the Indian sector of the Antarctic Ocean was carried out during the cruise of R. V. KAIYO MARU of the Fisheries Agency, from December 1979 to March 1980. The chlorophyll a content in the surface water was measured at stations from Fremantle to the station of 61°S, 100...

Measurement of chlorophyll a in the Indian sector of the Antarctic Ocean was carried out during the cruise of R. V. KAIYO MARU of the Fisheries Agency, from December 1979 to March 1980. The chlorophyll a content in the surface water was measured at stations from Fremantle to the station of 61°S, 100°E (1/7-1/15,1980) and from the station of 61°S, 120°E to Melbourne (1/27-2/8,1980). The surface water chlorophyll a content in the former course ranged from 0.05 to 0.44mg/m^3,and in the latter it ranged from 0.02 to 0.18mg/m^3. Surface water chlorophyll a was larger on the outward leg than on the homeward leg. The chlorophyll a content at 36 stations which were arranged along five transections in the survey area was measured on water samples taken from 10 layers between the surface and the depth of 200m.
