A possible correlation of stratigraphic levels between GSDS1 and GSDS2 profiles, using rock magnetic parameters such as S−0.1T ratio, NRM580°C/NRM20°C ratio, and MDFNRM/MDFARM ratio, with the variations of NRM0mT/ARM0mT and NRM40mT/ARM40mT ratios (possible RPI proxies). Upward-pointing arrows in the MDFNRM/MDFARM—depth graph denotes “higher than the value of the data point”. This correlation enables the raw depth of the GSDS2 profile to convert into the GSDS1 depth scale (cmcd), with downward shifts by 1.1 cm for the 7.1–20.3 cm raw depth, by (0.9 + 0.3*x) cm (x, distance between the raw depth and 23.1 cm) for the 23.1–36.3 cm raw depth, and by 5.0 cm for the 38.0–50.0 cm raw depth.
