Measurements of Quaternary nannofossils from Deep Sea Drilling Project Site 593 on Challenger Plateau, off western New Zealand, indicate that the difference in the delta (super 13) C of nannofossils and benthic foraminifers, defined as delta (super 13) C, is strongly correlated.completedQuaternary geologyalgaeC-13/C-12calcareous compositioncarbonCenozoicdeep-sea sedimentationisotopesmarine sedimentationmarine sedimentsmicrofossilsnannofossilsoceanographyPacific OceanPlantaeproductivityQuaternarysedimentationsedimentsSouth PacificSouthwest Pacificstable isotopesTasman SeathallophytesWest PacificEnglishgeoscientificInformation146.5500174.3000-51.0000-30.0000Tasman Sea
