Coastal and Terminus History of the Eastern Amundsen Sea Embayment, West Antarctica, 1972 - 2011

This data set provides a coastline history of the eastern Amundsen Sea Embayment and terminus histories of its outlet glaciers derived from those coastlines. These outlet glaciers include Smith, Haynes, Thwaites, and Pine Island Glaciers. The coastlines were derived from detailed tracing of Landsat imagery between late 1972 and late 2011 (at a scale of 1:50,000). The data set also uses some additional data from other sources. The terminus histories are calculated as the intersections between these coastlines and 1996 flowlines. Data are available via FTP in ESRI shapefile and comma separated value (.csv) formats.本数据集涵盖阿蒙森海海湾（Amundsen Sea Embayment）东部的海岸线演化历史，以及基于上述海岸线提取的该区域外流冰川（outlet glaciers）的终端变化序列。涉及的外流冰川包括史密斯冰川（Smith Glacier）、海恩斯冰川（Haynes Glacier）、思韦茨冰川（Thwaites Glacier）与派恩岛冰川（Pine Island Glacier）。本次研究的海岸线数据通过对1972年末至2011年末的陆地卫星（Landsat）影像开展详细人工追踪获取，解译比例尺为1:50000。本数据集同时整合了其他来源的补充数据。终端变化序列通过上述海岸线与1996年冰川流线的交点计算得到。 本数据集可通过文件传输协议（FTP）获取，数据格式包含ESRI形状文件（ESRI shapefile）与逗号分隔值（.csv）格式。
