过去２１Ｍａ以来大洋表面ｐＨ值的替代物──有孔虫中的硼同位素Ａ．Ｊ．Ｓｐｉｖａｃｋ等在ＯＤＰ８０３Ｄ孔（２°２５．９８′Ｎ，１６０°３２．４６′Ｅ；水深３４１０ｍ）中分离出了孔隙水和有孔虫样品。该孔从顶部至２２０ｍ处主要由９９％以上的生源沉积物与碳酸...
The surrogate of the pH of the ocean surface since the last 21 Ma - Boron isotope A in foraminifera. J. Porous water and foraminifer samples were separated by Spivack et al. In ODP803D wells (2 ° 25.98’N, 160 ° 32.46’E; water depth 3410m). The hole from the top to 220m mainly by more than 99% of the raw sediments and carbonic acid ...
