Messages for modern times – left behind by ice sheets and embedded in ice shelves John England has been studying glacial and postglacial environmental change across the Canadian Arctic Archipelago for over 40 years. Recent research supported by his NSERC Northern Research Chair has led to new discoveries concerning environmental change at high latitudes. To illustrate this, John will tie together several new themes that his research group is focussing on: A fundamental reinterpretation of the history of the northwest Laurentide ice Sheet including the northeast limit of Beringia and the resubmergence of the Bering Strait. Documentation of a former ice shelf that formed catastrophically during the deglaciation of the northwest Laurentide Ice Sheet, and its relevance to both the demise of the ice sheet and as an analogue for modern day west Antarctica under a warming global climate. The recent documentation of the age of the extant sea-ice ice shelves on Ellesmere Island that constitutes the most resistant core of the diminishing modern Arctic Ocean sea ice regime.
