Research at Undergraduate Institutions: Development of an On-line GIS Repository of Geological Data from the Ford Ranges, Marie Byrd Land, & Application to Cenozoic Paleogeogra

知识价值：这项工作将创建一个基于地理信息系统的福特山脉地质数据集存储库，这些数据集将通过互联网以地理信息系统和交互式网络格式提供。拟议的项目将把地质研究成果与南极地理空间信息中心提供的世界观图像和高分辨率TMA摄影相结合。该项目的目标是：1)开发一个基于互联网的地质数据共享系统；2)将这些数据与高分辨率摄影和图像相关联，将分析范围从岩石暴露区域扩展到完全冰川覆盖的区域；3)为本科生提供一个令人兴奋的环境，在这个环境中，他们可以获得GIS的基本技能和分析经验，同时了解物理化学原理。本研究将使用地理信息系统（GIS）对南极西部气候、冰盖或构造具有重要意义的地质冰川环境进行调查和解释，并通过对已发表的地质文献的深入研究进行补充，通过这些研究，学生将学会批判性思考，解决问题，并通过方法和数据集进行实验，以找到当代科学问题的解决方案。这些地质数据和基岩物理参数的编纂是ANTscape和南极气候演化科学家对过去古地形进行定量分析所需要的，并可作为不断改进的气候演化和冰盖模型的输入数据。更广泛的影响：作为这项工作的一部分，三名攻读高级论文的本科生将在探索南极气候演变的研究问题时熟练掌握地理信息系统。这项工作将使科学界能够访问来自西南极洲福特山脉的地质数据的在线存储库，这些数据将被放置在卫星图像提供的更大的地理空间框架中。对选定地区和时间间隔的古海拔的解释将广泛用于气候/冰盖建模者和冰川地质学家。岩石学、地质年代学和构造数据对于固体地球科学家在冈瓦纳前吸积边缘的部分进行工作将是有价值的。

Intellectual Merit: This work will create a GIS-based repository of geological data sets from the Ford Ranges that will be made available via the Internet in both GIS and interactive web format. The proposed project will integrate the products of geological research with WorldView imagery and high resolution TMA photography available from the Antarctic Geospatial Information Center. The aims of the project are: 1) to develop an internet-based system for sharing of geological data, 2) associate these data with high resolution photography and imagery to extend analysis from areas of rock exposure to completely glaciated areas, and 3) to provide undergraduates with an exciting context in which to acquire fundamental skills and analytical experience in GIS together with an understanding of physical-chemical principles. The research will use GIS for inquiry and interpretation of a geological-glacial setting that has significance for climate, ice sheet, or tectonics in West Antarctica, augmented by in-depth study of published geological literature, through which students will learn to think critically, problem-solve, and experiment with methods and data sets in order to find solutions to contemporary scientific questions. This compilation of geological data and bedrock physical parameters is needed for the quantitative analysis of past paleotopography by ANTscape and Antarctic Climate Evolution scientists, and may be used as input data for continually more refined climate evolution and ice sheet models.Broader impacts: As part of this work three undergraduates pursing senior theses will develop proficiency in GIS while exploring research questions about Antarctic climate evolution. This work will enable the scientific community to access an on-line repository of geological data from the Ford Ranges, West Antarctica that will be placed within the larger geospatial framework offered by satellite imagery. Interpretations of paleoelevations for selected regions and time intervals will be of broad use for climate/ice sheet modelers and glacial geologists. Petrological, geochronological, and structural data will be of value for solid earth scientists conducting work in segments of the former accretionary margin of Gondwana.
