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.

这项研究的重点是两个主题：纽芬兰冰帽的动态在最后一次冰期从离岸撤退到最后融化的内部;和纽芬兰周围的海平面波动的历史，以应对冰川消退。将通过审查“纽芬兰数字地形数据库”和实地绘制冰川地形图来调查冰川消退动态。 该提案中的一项新举措是将利用多波束声纳绘制的近海海底冰川地貌数据与利用航空照片和卫星图像绘制的陆上地貌数据相结合。 特别感兴趣的研究课题是在纽芬兰冰帽和冰边缘撤退的时间和配置前冰流的证据。 结果应提供新的漂移勘探研究的潜力，并将立即应用于纽芬兰省的矿产勘探行业。
