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

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.
