The dataset consists of planktic stable oxygen isotope data of cores PS1878, PS1243, JM11-FI-19PC and MD99-2284 vs. depth (m) as well as age (ka) from the age models constructed by correlation of the records. As the base for the chronological framework of the records, we used core MD99-2284 as this record exhibits the highest temporal resolution and has a robust chronology established by aligning variations in downcore sea-surface temperatures with synchronous changes in the hydroclimate record from southern Sweden (Muschitiello et al., 2020) in the interval between 10 ka and 14.8 ka. For the older part of the records, we use the chronology of core JM11-FI-19PC which was previously aligned with the North Greenland Ice Core Project (NGRIP) ice core based on tephras, δ18O, magnetic susceptibility, and K/Ti records (Ezat et al., 2014, 2017). To align the chronologies of the presented cores, we used their published planktic δ18O records based on Neogloboquadrina pachyderma (Bakke et al., 2009; Bauch et al., 2001; Ezat et al., 2016; Hoff et al., 2016; Telesiński et al., 2014). We correlated the records using visual tie points as well as the Saksunarvatn ash which is present in cores JM11-FI-19PC and MD99-2284 and the Vedde ash found in JM11-FI-19PC, MD99-2284 and PS1243.
