An overview of the planktonic foraminiferal fauna in waters off the Kerala Coast, south-west India during summer
Twentyeight species of planktonic Foraminifera are recorded from 46 plankton samples collected from 27 stations of 5 traverses along the Kerala Coast. The mean abundance of total foraminiferal sepcimens of all the stations in each traverse shows that it increases from south to north. Two distinct fo...
