Stable oxygen and carbon isotopes of benthic foraminifera from IODP Site U1534

Dataset is comprised of stable isotopes (oxygen and carbon) of benthic foraminifera from sediments from International Ocean Discovery Program (IODP) Expedition 382, Site U1534, South Falkland Sediment Drift. 53.18967 S, 58.76083 W (605 m water depth). The sediment cores were collected from 3 holes using the advanced piston corer onboard RV Joides Resolution from site U1534 between 29/03/2019 and 02/04/2019. Suitable specimens of benthic foraminifera were identified and picked from the >250 micron size fraction sediment at BAS between March 2020 and May 2021. Isotope analysis was carried out between March-August 2021. The data were collected as part of a project aiming to investigate the sensitivity of the Atlantic Meridional Overturning Circulation to variability in Pacific-Atlantic connectivity via the 'cold water route'. Dr Victoria Louise Peck was the principle investigator for this project. Funding provided by NERC UKIODP moratorium grant NE/T010908/1 and analytical support from NEIF steering committee application IP-1950-119.

本数据集涵盖采自南福克兰沉积物漂移区国际大洋发现计划（International Ocean Discovery Program, IODP）382航次U1534站位沉积物中底栖有孔虫的稳定同位素（氧同位素与碳同位素）数据。该站位地理坐标为南纬53.18967°、西经58.76083°，水深605米。2019年3月29日至4月2日期间，科考船"乔迪斯·决心号"（RV Joides Resolution）搭载的先进活塞取芯器于U1534站位的3个钻孔中采集了沉积物岩芯。2020年3月至2021年5月期间，英国南极调查局（BAS）的科研人员从粒径大于250微米的沉积物组分中，挑选并鉴定出符合要求的底栖有孔虫标本。同位素分析工作于2021年3月至8月间完成。本数据集采集自一项研究项目，该项目旨在通过"冷水通道"探究大西洋经向翻转环流（Atlantic Meridional Overturning Circulation, AMOC）对太平洋-大西洋连通性变化的敏感性。该项目的首席研究员为维多利亚·路易丝·佩克博士。本研究由英国自然环境研究委员会（NERC）UKIODP延期资助项目NE/T010908/1提供资金支持，并由NEIF指导委员会申请的IP-1950-119项目提供分析技术支持。
