Geomorphic map of Rauer Group

The GIS data was produced following a three week expedition to the region onboard the Alfred Wegener Institute research vessel Polarstern (cruise ANT-XXIII/9) in 2007, and subsequent analysis of aerial and field photography on return to Australia. The results are discussed in the expedition report and the following manuscripts. Cosmogenic exposure samples that will further constrain the age of ice retreat in the region are expected to be finalised during 2012. The data are intended to accompany existing polygons that detail the lakes, bedrock and penguin breeding sites (i.e. areas of biogenic sediment) from the area that are already present in the AAD digital database.

本地理信息系统（GIS）数据采集自2007年搭载阿尔弗雷德·魏格纳研究所（Alfred Wegener Institute）“极星号（Polarstern）”研究船开展的为期三周区域科考航次（ANT-XXIII/9航次），并于返回澳大利亚后对航拍及实地摄影资料进行后续分析处理后生成。相关研究成果已在本次科考报告及后续发表的多篇学术论文中予以阐述。用于进一步限定该区域冰川消退年代的宇宙成因暴露样品，预计将于2012年完成最终分析。本数据集旨在配套澳大利亚南极局（AAD）数字数据库中已有的区域矢量多边形数据，后者详细标注了该区域的湖泊、基岩及企鹅繁殖地（即生物沉积分布区）。如需获取更多信息，请查阅下载包中的Word文档。
