Abstract:
Results are examined of determinations of chlorophyll in seawater suspension by fluorescent and spectrophometric methods in the Southwest Indian Ocean near the African coast and in the Seychelles-Mauritius Plateau area in July-November 1977. During the study period near the African coast, the most productive regions, where the weighted average particulate chlorophyll concentration in the photic zone was greater than 0.5 µg/l, were off the Mozambique coast (near the mouth of the Zambezi River and in Delagoa Bay) and also off the coast of Tanzania, near the the Pemba and Zanzibar Islands. The most favorable conditions for growth of phytoplankton, i.e., a combination of distinct water stratification with intense upwelling, were observed in the equatorial divergence zone in the region of the Seychelles and Amirante Islands, where chlorophyll concentration in the layer of the maximum was as high as 3.4 µg/l. This region can be considered as one of the most productive regions of the Indian Ocean.
