10Be and 9Be concentrations in Black Sea sediment core M72/5-22GC-8 covering Termination 2 (133.5 - 127.8 ka BP)

10Be and 9Be records spanning Termination 2 (133.5 – 127.8 ka BP) were obtained from freeze-dried and homogenized samples of Black Sea sediment core M72/5-22GC-8 at 0.5 cm resolution. 10Be concentrations were measured using a MILEA accelerator mass spectrometry (AMS) system in 2021. 9Be concentrations analyzed using inductively coupled plasma mass spectrometry (ICP-MS, iCAP Q, Thermo Fisher Scientific) in 2021. Sediment core M72/5-22GC-8 was recovered from the south-eastern Black Sea (Archangelsky Ridge, 42°13.5'N, 36°29.6'E, 847 m bsl.) using a gravity corer during RV Meteor cruise M72/5 in 2007. Primary objective of the measurements was to establish time-series of 10Be and 9Be variability at multi-decadal resolution.

跨越终止期2（133.5–127.8 ka BP）的¹⁰Be和⁹Be记录，取自黑海沉积物岩芯M72/5-22GC-8经冻干并均质化的样本，分辨率为0.5 cm。¹⁰Be浓度于2021年采用MILEA加速器质谱（accelerator mass spectrometry, AMS）系统测定；⁹Be浓度则于2021年通过电感耦合等离子体质谱（inductively coupled plasma mass spectrometry, ICP-MS，iCAP Q，Thermo Fisher Scientific）分析获得。沉积物岩芯M72/5-22GC-8是2007年RV Meteor考察航次M72/5期间，使用重力取样器在黑海东南部（Archangelsky Ridge，42°13.5'N，36°29.6'E，水深847 m bsl.）采集的。本研究测量的主要目标是建立多十年分辨率的¹⁰Be和⁹Be变率时间序列。
