δ18O and δ13C stable isotopes of benthic foraminifera Uvigerina peregrina from sediment core GeoB9506-1

The present data sets contain the measured stable isotope (d18O and d13C) data on 142 samples of Uvigerina peregrina and 77 of Cibicidoides wuellerstorfi from core GeoB9506-1. Part of the measurements comes from 10cc of sediment collected every 2.5 cm from the gravity core (working/archive halves) from 0 to 260 cm at the GeoB Core Collection at the MARUM – Center for Marine Environmental Sciences, University of Bremen, Germany. Each sample was (1) washed with deionized water through a 63 µm sieve, then (2) dried for less than 24 hours at 45°C, and (3) dry sieved through 63 µm, 125 µm, 150 µm, and 250 µm. Finally, the washed sediment with a size >150 µm was used to retrieve between 8-10 tests of the used species when possible. The remaining measurements for U. peregrina (from 260 to 978 cm core depth) comes from already washed sediment provided by the GeoB Core Collection at the MARUM. In addition, previously published stable isotope data (d18O and d13C) of 189 samples of Cibicidoides wuellerstorfi and 191 samples of Melonis barleeanus from the same core were added (Mulitza et al., 2022 - https://doi.org/10.1594/PANGAEA.936747) and are properly indicated in the data set. Measurements were runned on a Finnigan 252 connected to a Gasbench, at MARUM- Center for Marine Environmental Sciences of the University of Bremen (https://www.marum.de/en/Infrastructure/Mass-Spectrometry-on-Inorganic-Samples.html).
