The development of ocean currents and the response of the cryosphere on the Southwest Svalbard shelf over the Holocene

We present multi-proxy data, including benthic foraminiferal assemblages, carbon and oxygen stable isotopes, total organic carbon (TOC) and total carbon (TC), ice-rafted debris (IRD), x-ray fluorescence, biomarkers (alkenones, sterols), and pigment data, covering the past 11.4 kyr BP. These data are derived from sediment core OCE2019-HR7-GC, retrieved from the Southwest Svalbard shelf (76°56.513'N, 14°54.072'E, 133 m water depth) during the AREX 2019 expedition aboard RV Oceania. Benthic stable isotopes were primarily measured on Elphidium clavatum. The dataset is presented in relation to both age and depth.

本研究提供了涵盖过去11.4千年BP的多指标数据，包括底栖有孔虫组合（benthic foraminiferal assemblages）、碳氧稳定同位素（carbon and oxygen stable isotopes）、总有机碳（TOC）与总碳（TC）、冰筏碎屑（IRD）、X射线荧光（x-ray fluorescence）、生物标志物（biomarkers）（含烯酮、甾醇）及色素数据。这些数据来源于OCE2019-HR7-GC沉积岩芯（sediment core），该岩芯是在AREX 2019考察期间，由“大洋洲”号科考船（RV Oceania）于斯瓦尔巴群岛西南陆架（76°56.513'N，14°54.072'E，水深133米）获取。底栖稳定同位素主要在克拉瓦圆片虫（Elphidium clavatum）上进行测量。本数据集同时按年代和深度维度进行呈现。
