The relative abundance (%) of planktonic foraminifera over time in core BAR 9403, located off the coast of Sumatra
The advent of deep-sea drilling in the 1950's prompted the use of planktonic foraminifera (unicellular protozans) as palaeoceanographic indicators. They provide a natural archive of past environmental changes due to their global distribution, their prolific productivity and sensitivity to envir...
