资源简介：
Upper Miocene foraminiferal nannofossil ooze and chalk from DSDP Hole 552A in the northeast Atlantic Ocean have been closely sampled for biostratigraphic, paleomagnetic, and stable-isotopic studies. Sampling at 10-cm intervals resulted in an uppermost Miocene isotope stratigraphy with a 1000- to 3000-yr. resolution. […]
针对东北大西洋海域深海钻探计划（Deep Sea Drilling Project, DSDP）552A钻孔所获取的上中新世有孔虫钙质超微化石软泥与白垩沉积，研究人员已对其开展了密集系统取样，以支撑生物地层学、古地磁学及稳定同位素相关研究。通过以10厘米间隔实施取样，最终获得了分辨率介于1000至3000年的上中新统顶部同位素地层序列。[…]
