Benthic Foraminifera
The tests of benthic foraminifera are preserved in the sediments of much of the global sea floor and serve as a tool for stratigraphic, paleoecological and paleoceanographic investigations. With respect to GOA benthic foraminifera mainly serve as signal carrier for measurements of radiocarbon, oxygen and carbon isotopes and Mg/Ca
