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

这项研究集中于两个主题：最后一次冰川从近海消退到内陆最终融化期间纽芬兰冰盖的动力学；以及纽芬兰周围海平面因冰川消融而波动的历史。将通过检查“纽芬兰数字地貌数据库”和现场绘制冰川地貌图来调查冰川消融动力学。该提案中的一项新举措是将使用多波束声纳绘制的近海海床冰川地貌数据与根据航空照片和卫星图像绘制的陆上地貌数据结合起来。特别令人感兴趣的研究课题是纽芬兰冰帽中以前的冰流的证据，以及冰缘退缩的时间和形态。研究结果将为漂移勘探研究提供新的潜力，并将立即应用于纽芬兰的矿产勘探行业。

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.
