Abstract

Time-scale studies on surface productivity and related hydrography from two fixed stations off Visakhapatnam were carried out during premonsoon and winter months of 1987-1989. The interrelations between certain hydrochemical parameters, primary production and plant pigments were investigated. Upwelling was found to occur near the coast during March-May period. Replenishment of phsophate during upwelling was indicated. An exceptionally high value of phaeopigments (10.16 mglm3) was recorded. Significant positive correlation between pigments and productivity and negative correlation between pigments and secchi disc depth were observed.
