(Table T1) Pore-water strontium content, and Sr isotope composition and ages of pore waters and sedimentary carbonates of ODP Leg 171B sites@en

Strontium concentrations and 87Sr/86Sr values were measured on pore-water and sedimentary carbonate samples from sediments recovered at Sites 1049-1053 on the Blake Spur during Ocean Drilling Program Leg 171B. These sites form a 40-km-long depth transect extending along the crest of the Blake Spur from near the upper edge of the Blake Escarpment (a steep cliff composed of Mesozoic carbonates) westward toward the interior of the Blake-Bahama Platform. Although these sites were selected for paleoceanographic purposes, they also form a hydrologic transect across the upper eastern flank of the Blake-Bahama Platform. Here, we use pore-water strontium concentrations and isotopes as a proxy to define patterns of fluid movement through the flanks of this platform. […]本数据集包含大洋钻探计划（Ocean Drilling Program）第171B航次于布莱克海脊（Blake Spur）1049至1053站位钻获的沉积物中孔隙水与沉积碳酸盐岩样品的锶浓度及87Sr/86Sr同位素比值测试数据。这些站位构成一条长40千米的深度断面，沿布莱克海脊脊部延伸，从接近布莱克陡崖（由中生代碳酸盐岩构成的陡峭崖壁）的上缘向西延伸至布莱克-巴哈马台地（Blake-Bahama Platform）内部。尽管选取这些站位的初衷为开展古海洋学研究，它们同时也构成了横跨布莱克-巴哈马台地东部上侧翼的水文断面。本研究以孔隙水锶浓度与同位素比值作为替代指标，阐明该台地侧翼的流体运移模式……
