Abstract: Geomorphometric modeling and mapping of ice-free Antarctic areas can be applied for obtaining new quantitative knowledge about the topography of these unique landscapes and for the further use of morphometric information in Antarctic research. Within the framework of a project of creating a physical geographical thematic scientific reference geomorphometric atlas of ice-free areas of Antarctica, we performed geomorphometric modeling and mapping of five key coastal oases of Enderby Land, East Antarctica. These include, from west to east, the Konovalov Oasis, Thala Hills (Molodezhny and Vecherny Oases), Fyfe Hills, and Howard Hills. As input data, we used five fragments of the Reference Elevation Model of Antarctica (REMA). For the coastal oases and adjacent ice sheet and glaciers, we derived models and maps of eleven, most scientifically important morphometric variables (i.e., slope, aspect, horizontal curvature, vertical curvature, minimal curvature, maximal curvature, catchment area, topographic wetness index, stream power index, total insolation, and wind exposition index). In total, we derived 60 maps in 1:50,000 and 1:75,000 scales. The obtained models and maps describe the coastal oases of Enderby Land in a rigorous, quantitative, and reproducible manner. New morphometric data can be useful for further geological, geomorphological, glaciological, ecological, and hydrological studies of this region. Show Chinese abstract

Abstract: 地貌计量建模和无冰南极地区的制图可用于获取关于这些独特景观地形的新定量知识，并用于南极研究中的进一步地貌计量信息。 在创建无冰南极地区物理地理主题科学地貌计量图集的项目框架内，我们对埃默里地的五个关键沿海绿洲进行了地貌计量建模和制图。 这些绿洲从西向东依次为科诺瓦洛夫绿洲、塔拉山（摩洛迪奇尼和韦切尼绿洲）、菲夫山和霍华德山。 作为输入数据，我们使用了南极参考高程模型（REMA）的五个片段。 对于沿海绿洲及其相邻的冰盖和冰川，我们推导出了十一项最重要的科学地貌计量变量模型和地图（即坡度、坡向、水平曲率、垂直曲率、最小曲率、最大曲率、汇水区、地形湿润指数、河流动力指数、总辐射量和风暴露指数）。 总共生成了60幅1:50,000和1:75,000比例尺的地图。 所得模型和地图以严格、定量和可重复的方式描述了埃默里地的沿海绿洲。 新的地貌计量数据可能对该地区的地质学、地貌学、冰川学、生态学和水文学研究有帮助。
