Geomorphology of Ulu Peninsula, James Ross Island, Antarctica

This study presents a 1:25,000 geomorphological map of the northern sector Ulu Peninsula, James Ross Island, Antarctic Peninsula. The covers an area c. 250 km2, and documents landforms surficial sediments one largest ice-free areas in Antarctica, based on remote sensing field-based mapping. large-scale landscape features are determined by underlying Cretaceous sedimentary Neogene volcanic geology, which has been sculpted overlying ice masses during glacial periods. Paraglacial periglacial superimposed upon remnant features, reflecting post-glacial evolution landscape. can be broadly separated into three sectors, according to dominant contemporary Earth-surface processes; specifically, glacierised southern sector, paraglacial-dominated eastern periglacial-dominated central/northern sector. provides basis for further interdisciplinary research, insight potential future other parts Peninsula as climate warms.
