Abstract. In Antarctica, the presence of sea ice not only plays a critical role in climate system but also contributes to enhancing stability floating shelves. Hence, investigating past ice-proximal conditions, especially across glacial–interglacial cycles, can provide crucial information pertaining variability and deepen our understanding ocean–ice–atmosphere dynamics feedback. this study, we apply multiproxy approach, combination with numerical modeling, explore environmental variability....
Abstract. In Antarctica, the presence of sea ice in front shelves promotes their stability and prevents risk catastrophic collapse as witnessed recent events along Antarctic Peninsula. Investigating past ice-proximal sea-ice conditions, especially across glacial-interglacial cycles, can provide crucial information pertaining to variability deepen our understanding ocean-ice-atmosphere dynamics feedbacks. this study, we apply a multiproxy approach, analyzing novel biomarker IPSO25 (a...
The age model of marine sediment core PS118_63-1 was first established using a comparative analysis between the XRF-Ti record with EDML δ 18 O (Supplementary Fig. S1).Furthermore, MIS 5/6 boundary is identified by biostratigraphic marker Rouxia leventerae (ca.130 ka BP; Zielinski et al., 2002).Since <1% relative abundance found at depth 6.19 m (0.6%), we estimated last occurrence to be around 6.2 m.Planktic foraminifera were also selected for AMS 14 C-dating Table S1) Mini Carbon Dating...
Antarctic sea ice plays a crucial role in buttressing shelves, enhancing their stability, and protecting them from potential catastrophic collapse &#8211; significance underscored by recent calving events along the Peninsula. Presence or absence of Southern Ocean, details its distribution patterns, therefore have relevance far beyond realm high latitudes Hemisphere. Investigating past sea-ice conditions proximity to changes over time, particularly across glacial-interglacial cycles, is...
