深海岩芯中底栖有孔虫Cibicidoides wuellerstorfi和Uvigerina peregrina群的冰期至间冰期δ 13 C记录不能用一个普遍有效的常数进行调整。U. peregrina类群与有机碳的积累速率密切相关，表明存在局部的“生境效应”; wuellerstorfi相对于碳通量独立变化，并记录了周围底层水同位素组成δ 13 C的波动。
The glacial to interglacial δ13C records of the benthic foraminifera Cibicidoides wuellerstorfi and the Uvigerina peregrina group from deep-sea cores cannot be adjusted by a generally valid constant. The δ13C values of the U. peregrina group largely correlate with the accumulation rates of organic carbon, suggesting a local "habitat effect"; those of C. wuellerstorfi vary independently with respect to the carbon flux and record fluctuations in the δ13C of the ambient bottom water isotopic composition.
