Intellectual Merit: The PIs propose a two-year project to map the distribution of climate-sensitive landforms throughout Northern Victoria Land between the Convoy Range and Cape Adare. This work will produce geospatial products to aid their geomorphic work on ice sheet stability and landscape evolution. Specifically, the PI will investigate the potential for extensive surface melting and ice-sheet retreat with modest warming in areas north of the Convoy Range in Northern Victoria Land. The hypothesis is that if key landform elements of the Dry Valleys assemblage are lacking in NVL it suggests a major variation in current climate conditions, and perhaps changes in climate evolution. The proposed work will also benefit the broader research community, as it will demonstrate the potential for using geospatial imagery in geomorphic research and produce geospatial products that can be used by other researchers. Broader impacts: This work will help the research community better leverage the investment being made in the Polar Geospatial Center (PGC) and will help further demonstrate the significance of satellite imagery for doing ?virtual? field work in the Polar regions. More effective use of satellite imagery by field scientists in Antarctica will help reduce the logistical footprint on the Continent. The proposed research will support one graduate student at Boston University who will be trained in image analysis, map production, Antarctic geomorphology, and geospatial technologies. The proposed work will help to forge stronger links between PGC and Boston University?s Digital Image Analyses Lab (DIAL).

智力优势：PI提出了一个为期两年的项目，以绘制整个北方维多利亚土地之间的康诺利山脉和阿代尔角气候敏感的地形分布。这项工作将产生地理空间产品，以帮助他们在冰盖稳定性和景观演变方面的地貌工作。具体来说，PI将调查北方维多利亚地康诺利山脉以北地区大范围表面融化和冰盖退缩的潜力。假设是，如果关键的地形要素的干谷组合是缺乏在NVL，它表明在目前的气候条件下的一个重大变化，也许在气候演变的变化。拟议的工作还将使更广泛的研究界受益，因为它将展示在地貌研究中使用地理空间图像的潜力，并制作可供其他研究人员使用的地理空间产品。更广泛的影响：这项工作将有助于研究界更好地利用极地地理空间中心（PGC）的投资，并将有助于进一步证明卫星图像的重要性。虚拟？在极地进行实地考察。南极实地科学家更有效地利用卫星图像将有助于减少对南极大陆的后勤影响。拟议的研究将支持波士顿大学的一名研究生，他将接受图像分析、地图制作、南极地貌学和地理空间技术方面的培训。 拟议中的工作将有助于PGC和波士顿大学之间建立更紧密的联系？数字图像分析实验室（DIAL）。
