Recent planktonic foraminifera from the sediment off Karwar and Mangalore
Abstract
Eleven samples collected from the shelf-slope regions off Karwar and mangalore transects of the Arabian Sea, yielded fifteen planktonic foraminiferal species, which are identified and described. There is a progressive increase in the percentage of planktonic foraminifera from the shore towards the slope, indicative of a regulated sediment discharge and rate of sedimentation in the area. All the species represented are typical warm-water fauna, with one exception. Undoubted, though rare, @iGlobigerina pachyderma@@ (Ehrenberg) is present in the slope sediment off Mangalore area but not in the Karwar region, which is very significant since it delineates its northern extension beyond the equator
