Abstract

Interpreting the dynamics and history of ice shelves is important for evaluating the response of ice sheets to climatic and oceanographic changes. Ice shelves have received considerable attention in the Antarctic Peninsula, as they have undergone sequential, rapid col-lapse (Vaughan & Doake 1996; Morris & Vaughan 2003; Cooke et al. 2005; Cook & Vaughan 2010), following a long period during which their grounding-lines had been stable (Rebesco et al. 2014). A detailed understanding of ice-shelf character and behaviour is therefore of immediate interest, yet the geological record of ice shelves is largely unknown. Geological and structural glaciological data can provide vital information concerning the evolution of ice shelves over time. However, apart from a few examples of moraines produced by floating glacier ice in the Canadian Arctic Archipelago
