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.

本研究集中于两个主题：末次冰期期间纽芬兰冰盖从离岸退缩到内部最终融化的动力学过程；以及纽芬兰附近海平面波动的历史，以应对冰川消融。通过对“纽芬兰数字地貌数据库”和冰川地貌的实地测绘，将研究冰川消融动力学。该提案中的一项新举措是将来自海底的冰川地貌数据（使用多波束声纳绘制）与岸上的地貌数据（使用航空照片和卫星图像绘制）结合起来。特别感兴趣的研究主题是纽芬兰冰帽中以前冰流的证据以及冰边缘退缩的时间和结构。结果将为漂移找矿研究提供新的潜力，并将立即应用于纽芬兰的矿产勘探工业。
