项目摘要

Specific objectives:To document and map the landforms and landscapes in Promethei Terra and Deuteronilus Mensae and to assess the case for their formation by wet-based or cold-based glacial processes.To assess whether the Hubbard et al. (2011) model for the formation and movement of glacier-like forms applies to other regions on Mars.This project will examine glacial landscapes on Mars. It will focus on two study regions that reflect some of the most important discoveries of the last 10 years, namely: 1) observations of geologically recent glacial landforms in the mid- to low-latitudes that indicate significant deposition and mobility of ice or ice-rich material (Souness et al. 2012, Milliken et al. 2003); 2) Gamma ray and Neutron Spectrometer data showing high concentration of extant near-surface in certain mid- to low-latitude areas of Mars (Feldman et al. 2011). Taken together, these results suggest a dynamic recent climate, with the role of water in both the solid and liquid state being key. The first area of study will be the mid-latitude region of Promethei Terra, which shows spectral evidence of anomalously high quantities of near-surface water-ice, and contains viscous flow features that closely resemble terrestrial rock-glaciers, as well as possible fluvioglacial landforms. The second area of study will be the mid to high latitude area of Deuteronilus Mensae, which, in contrast to Promethei Terra, is not associated with spectral evidence of water ice, but has abundant evidence of glacier like forms (Squyres 1979, Morgan et al. 2009). A key element of this project will be to investigate and map the meter/decametre scale geomorphology of these areas and to determine whether the spectral signature of high water-ice content has a morphological counterpart. A second aspect of this project could incorporate glacial flow modelling to constrain the duration of activity and amount of debris on these features, or remotely sensed Earth analogue work, depending on the strengths and preferences of the candidate.Specific training will include the use of GIS in planetary data contexts, construction of digital terrain models from orbital and aerial images, planetary mapping techniques and general concepts in martian geomorphology/geology.

具体目标：记录和绘制Promethei Terra和Deuteronilus Mensae的地貌和景观，并评估它们是由湿基或冷基冰川过程形成的。评估Hubbard et al.（2011）关于冰川样形态形成和运动的模型是否适用于火星上的其他地区。这个项目将研究火星上的冰川景观。它将集中在两个研究区域，这些区域反映了过去10年来一些最重要的发现，即：1)在中低纬度地区对地质上最近的冰川地貌的观测表明冰或富冰物质的显著沉积和流动（Souness et al. 2012, Milliken et al. 2003）；2)伽马射线和中子星数据显示，在火星的某些中低纬度地区，现存的近地表生物浓度很高（Feldman et al. 2011）。综上所述，这些结果表明了一个动态的近期气候，而水在固态和液态的作用都是关键。第一个研究区域将是普罗米修斯Terra的中纬度地区，该地区显示出异常大量的近地表水冰的光谱证据，并包含与陆地岩石冰川非常相似的粘性流动特征，以及可能的河流冰川地貌。第二个研究区域将是Deuteronilus Mensae的中高纬度地区，与Promethei Terra相比，该地区与水冰的光谱证据无关，但有大量冰川形式的证据（Squyres 1979, Morgan et al. 2009）。该项目的一个关键要素将是调查和绘制这些地区的米/十米尺度地貌图，并确定高水冰含量的光谱特征是否具有形态学对应。该项目的第二个方面可以结合冰川流动模型，以限制活动的持续时间和这些特征上的碎片数量，或遥感地球模拟工作，这取决于候选人的优势和偏好。具体训练将包括在行星数据背景下使用地理信息系统、从轨道和航空图象建立数字地形模型、行星制图技术和火星地貌/地质学的一般概念。
