Abstract:
The age model for PS69/899-2 (doi:10.1594/PANGAEA.983936) was developed using a combination of stratigraphic markers and Undatable age-depth modeling routine (Lougheed and Obrochta, 2019). Stratigraphic markers employed include TEX86-based SST, RPI, radiocarbon ages on total sedimentary organic matter, and the last occurence datum of the diatom Rouxia leventerae (Zielinski et al., 2002). The TEX86-based SST record from core PS69/899-2 was aligned with the Antarctic temperature stack compiled from ice core data (Parrenin et al., 2013), while the RPI record was aligned with the PISO-1500 paleointensity stack (Channell et al., 2009). Radiocarbon ages were calibrated using the Marine 20 calibration data (Heaton et al., 2023), assuming a marine reservoir age of 1200 years for the Holocene and of 2200 years for glacial periods (Rafter et al., 2022).
