Stable carbon and oxygen isotopes of benthic foraminifera from sediment core POS457_889-1

R/V POSEIDON cruise POS457 aimed at sediment coring on the Iceland-Faroe Ridge, the shelf and slope areas south of Iceland, and on Reykjanes Ridge in order to reveal paleoceanographic and paleoclimatic information. Gravity corer 889-1 was recovered from southeast of Reykjanes Ridge close to Iceland (N Atlantic, 63°03.04'N 23°23.19'W, 923.0 m water depth). We present radiocarbon datings and high-resolution XRF-scanner element compositions of bulk sediments. In addition, we provide benthic and planktic stable oxygen and carbon isotopes, as well as planktic foraminiferal element ratios.

R/V海神号（R/V POSEIDON）科考航次POS457以冰岛-法罗海岭、冰岛以南陆架与斜坡区域，以及雷克雅内斯海岭的沉积物取芯为研究目标，旨在获取古海洋学与古气候学相关信息。重力取芯器（Gravity corer）889-1号回收自雷克雅内斯海岭东南部毗邻冰岛的海域（北大西洋，63°03.04'N 23°23.19'W，水深923.0米）。本数据集包含块状沉积物（bulk sediments）的放射性碳定年结果与高分辨率XRF扫描仪（XRF-scanner）元素组成数据。此外，还提供了底栖与浮游生物的稳定氧、碳同位素数据，以及浮游有孔虫（planktic foraminiferal）的元素比值数据。
