Relationship between magnetic susceptibility and sediment grain size since the last glacial period in the Southern Ocean off the northern Antarctic Peninsula – Linkages between the cryosphere and atmospheric circulation

Abstract Magnetic susceptibility (MS) values in Scotia Sea sediments showed strong correlations to ice core non-sea salt Ca2+ concentration (dust input), which emphasizes the role of atmospheric circulation in the Southern Ocean. As a result, the correlation between these values was suggested as a powerful tool for age reconstruction of marine sediments in the Southern Ocean. However, controls on MS variation in Scotia Sea sediments are not clear. In this study, we documented records of grain size, MS values (10−6 CGS/g) of bulk sediments, and MS values of sand-sized (>63 μm), coarse silt-sized (16–63 μm), and fine sediment fractions (
