Geomorphology of Stansbury Peninsula, Nelson Island, Antarctic Peninsula

The proglacial landscapes of Antarctica offer critical insights into past and ongoing deglaciation processes and the impacts of climate change. This study presents the first geomorphological map of the proglacial part of Stansbury Peninsula (Rip Point) and Cariz Cabo Cape in the northern part of Nelson Island. We identify and characterise a variety of glacial, proglacial, paraglacial, and periglacial landforms using high-resolution drone imagery, fieldwork, and geological data. The defined landforms presented reflect a complex interplay of erosional and depositional processes shaped by multiple glacial advance-retreat cycles since the Last Glacial Maximum, with evidence for significant glacial activity during the Holocene. The presence of hyaloclastite and crystalline erratic boulders further contributes to the reconstruction of glacial dynamics in the region. Our findings provide a crucial dataset and baseline for studies on future Antarctic deglaciation, periglacial processes, and the expansion of proglacial landscapes driven by ongoing climate change.
