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

智力优势：这项工作将建立一个以地理信息系统为基础的福特山脉地质数据集储存库，通过因特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产品与南极地理空间信息中心提供的WorldView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系统，用于共享地质数据，2）将这些数据与高分辨率摄影和图像相关联，以将分析从岩石暴露区域扩展到完全冰川化区域，以及3）为本科生提供一个令人兴奋的背景，以获得GIS的基本技能和分析经验，并了解物理化学原理。该研究将使用GIS对南极洲西部的气候，冰盖或构造具有重要意义的地质冰川环境进行查询和解释，通过对已出版的地质文献的深入研究，学生将学会批判性地思考，解决问题，并尝试方法和数据集，以找到当代科学问题的解决方案。地质数据和基岩物理参数的汇编是需要过去的古地形定量分析的ANTscape和南极气候演变的科学家，并可能被用作输入数据不断更精细的气候演变和冰盖models.Broader影响：作为这项工作的一部分，三个本科生追求高级论文将开发GIS的熟练程度，同时探索有关南极气候演变的研究问题。这项工作将使科学界能够利用来自西南极洲福特山脉的地质数据联机储存库，这些数据将被置于卫星图像提供的更大的地理空间框架内。对选定区域和时间间隔的古海拔解释将广泛用于气候/冰盖建模者和冰川地质学家。岩石学，年代学和结构数据将是有价值的固体地球科学家进行工作的冈瓦纳前增生边缘的片段。

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.
