Abstract

A study of planktonic foraminiferal assemblages from 19 stations in the neritic and oceanic regions off the Coromandel coast, Bay of Bengal has been made using a multivariate statistical method termed as factor analysis. On the basis of abundance of 17 foraminiferal species, species were clustered into 5 groups with row normalisation and varimax rotation for Q-mode factor analysis. The 19 stations were also grouped into 5 groups with only 2 groups statistically significant using column normalisation and varinmx rotation for R-mode analysis. This assemblage grouping method is suitable because groups of species/stations can explain the maximum amount of variation in them in relation to prevailing environmental conditions in the area of study.
