Seasonal variations in the Indian Ocean along 110°E. III. Chlorophylls a and c

Abstract

The mean concentrations for all samples analysed were 0.17 µg/l for chlorophyll a and 0.22 µg/I. for chlorophyll c; there were 27 mg/m² of a and 35 mg/m² of c in the water column to 150 m. June-August gave the highest values. The model depth at which concentrations were greatest was 75 m. Diagrams of regression surfaces fitted to the results are given. Regression analysis showed that depth, latitude, and season affected the concentration of chlorophylls; latitude and season affected the column amount of chlorophylls.
