Opal and Ba/Ti ratio for IODP Holes 385-U1545A and 385-U1549A
收藏资源简介:
The dataset compiles paleoproductivity proxies from sediments recovered from the first 42.29 meters below the seafloor (mbsf) at Hole 385-U1545A, with a resolution of 30 cm for opal, Ba, Ti and Ba/Ti, and from the first 29.19 mbsf at Hole 385-U1549A, with a resolution of 60 cm for opal, Ba, Ti, and Ba/Ti. Sediment cores were obtained aboard the deep-sea vessel R/V JOIDES Resolution during International Ocean Discovery Program (IODP) Expedition 385 in the Guaymas Basin. The data includes Ages (cal yr BP), opal, Ba, Ti, Ba/Ti ratios, and opal difference between Site 385-U1545A and 385-U1549A.
本数据集整合了瓜伊马斯盆地(Guaymas Basin)国际大洋发现计划(International Ocean Discovery Program, IODP)第385次航次期间,由深海科考船“乔迪斯·决心号”(R/V JOIDES Resolution)获取的沉积物岩芯中的古生产力代用指标数据。其中,385-U1545A钻孔的有效取样深度为海底以下42.29米(meters below seafloor,mbsf)以浅,蛋白石、钡(Ba)、钛(Ti)及钡钛比(Ba/Ti)的分析分辨率为30厘米;385-U1549A钻孔的有效取样深度为海底以下29.19米(mbsf)以浅,上述指标的分析分辨率为60厘米。本次数据集涵盖的参数包括校准年BP(cal yr BP)、蛋白石、Ba、Ti、Ba/Ti比值,以及385-U1545A与385-U1549A两个钻孔的蛋白石差值数据。
