Margin Migration Rates and Dynamics: Siple Coast Ice Streams

Abstract: This product, based on prior data collected under NSF-OPP grant 8716604 (Echelmeyer and Harrison) and NSF-OPP grant 9117911 (Harrison), includes ice velocity data between stations S17 and UpB on the Upper Whillans Ice Stream, Siple Coast, West Antarctica, from January 1994 to January 1995. Velocities were measured using a total station, a surveying instrument that combines a digital theodolite and an Electronic Distance Measuring (EDM) device to measure horizontal and vertical angles, slope, and horizontal and vertical distances. Data are in ASCII and Excel formats, and are available via FTP.摘要：本数据集基于两项由美国国家科学基金会极地项目办公室（NSF-OPP）资助的前期采集数据，分别为编号8716604（Echelmeyer与Harrison主持）以及编号9117911（Harrison主持）的项目。数据集涵盖1994年1月至1995年1月期间，西南极洲锡普尔海岸上惠兰斯冰流（Upper Whillans Ice Stream）S17与UpB测站之间的冰流速数据。流速数据通过全站仪（total station）测得，该测量仪器集成了数字经纬仪与电子测距（Electronic Distance Measuring, EDM）装置，可同步测量水平角、垂直角、坡度以及水平与垂直距离。本数据集采用ASCII与Excel格式存储，可通过FTP获取。
