Strain fields on the Amery Ice Shelf using GPS

The data sets consist of static and kinematic GPS data collected on the mery Ice Shelf using Leica 399 receivers. Additional GPS data were collected at Beaver Lake, Hamm Peak, Moushino Is., New Year Nunataks, Jetty Peninsula, and Else Platform.Most data are provided in UNIX Z compressed RINEX (Receiver INdependent EXchange) format, as described in the IGS standards - see http://www.igs.org/productsSome data are compressed using the RINEX Hatanaka compression scheme.The standard RINEX file naming convention is used, i.e., an eight digit file name as bbbbddds.yyt, where bbbb refers to a four digit station name, ddd refers to the day number of the year, s refers to a session number and yyt is the file extension number where yy refers to the year and t defines the file type (o for observation file and n for navigation file. d indicates an observation file compressed using the Hatanaka compression scheme). All files are compressed using the UNIX Z compression scheme, as shown by the extension .Z. For example, base0010.98o.Z, base0010.98n.Z, base0010.98d.Z.The files are set out in the following directories on the submitted CD:season1998_1999\amery\amery\camp\beaverGPS data collected at the permanent stations at Casey, Davis and Mawson are available from Geoscience Australia - see http://www.ga.gov.au/geodesy/antarc/antgps.jspThe fields in this dataset are:marker numbermarker nameobserver/agencyapprox positionantennawavelengthGPSAmery ice shelf本数据集包含在埃默里冰架（Amery Ice Shelf）上使用徕卡Leica 399接收机采集的静态与运动学GPS数据。另有在海狸湖（Beaver Lake）、哈姆峰（Hamm Peak）、穆希诺岛（Moushino Is.）、新年冰原岛峰（New Year Nunataks）、码头半岛（Jetty Peninsula）以及埃尔塞平台（Else Platform）采集的额外GPS数据。绝大多数数据采用符合国际GNSS服务（International GNSS Service，IGS）标准的UNIX Z压缩RINEX（接收机独立交换格式，Receiver INdependent EXchange）格式存储，详情可参见http://www.igs.org/products。部分数据采用RINEX Hatanaka压缩方案进行压缩。本数据集采用标准RINEX文件命名约定，即文件名采用8位格式：bbbbddds.yyt，其中：bbbb为4位测站名称，ddd为年积日，s为会话编号，yyt为文件扩展名：yy代表年份，t用于定义文件类型（o为观测文件，n为导航文件，d代表采用Hatanaka压缩方案的观测文件）。所有文件均采用UNIX Z压缩方案，扩展名以.Z标识。示例如下：base0010.98o.Z、base0010.98n.Z、base0010.98d.Z。提交的光盘中，文件存储于以下目录：season1998_1999ameryamerycampeaver。在凯西站（Casey）、戴维斯站（Davis）与莫森站（Mawson）的永久测站采集的GPS数据可从澳大利亚地球科学局（Geoscience Australia）获取，详情可参见http://www.ga.gov.au/geodesy/antarc/antgps.jsp。本数据集包含以下字段： 标记编号 标记名称 观测者/机构 近似位置 天线波长 GPS 埃默里冰架
