(Appendix I) Distribution of Quaternary nannoflora at DSDP Site 90-594 east of South Island, Southwest Pacific@en

Estimates of relative species abundance of the nannoflora were made semiquantitatively by determining the percentage cover of a species per field of view at about 2400 X magnification. Abundance data are expressed as an estimate of calcite volume in order to calculate adjustments in delta18O due to non-equilibrium fractionation factors (vital effects) in various species. For CaCO3 values see Nelson et al. (1986) doi:10.1594/PANGAEA.688751通过统计约2400倍放大视野下单个物种的盖度百分比，对微型浮游植物群（nannoflora）的物种相对丰度进行半定量估算。为计算不同物种因非平衡分馏系数（生命效应，vital effects）引发的δ¹⁸O（delta18O）校正值，丰度数据以方解石体积估算值的形式予以表征。如需获取碳酸钙（CaCO3）的相关数值，请参阅Nelson等人（1986）的研究，DOI：10.1594/PANGAEA.688751
