Deglacial ice dynamics glacio-isostatic adjustments and relative sea-level history in Newfoundland

This research focuses on two themes: the dynamics of the Newfoundland ice cap during the last glaciation from retreat offshore to final melting in the interior; and the history of sea-level fluctuations around Newfoundland in response to deglaciation. Deglacial dynamics will be investigated through examination of the "Digital Landforms Database of Newfoundland" and field mapping of glacial landforms. A new initiative in this proposal is to combine glacial landform data from the seabed offshore, mapped using multibeam sonar, with landform data onshore, mapped from aerial photographs and satellite imagery. Topics of particular research interest are the evidence for former ice streams in the Newfoundland ice cap and the timing and configuration of ice-marginal retreat. Results should provide new potential for drift prospecting studies and will have immediate application to the mineral exploration industry in Newfoundland.
