Ice-Penetrating Radar Data Across Siple Coast Grounding Lines

Abstract: These data consist of ice-penetrating radar data collected on the ground across the grounding line near Siple Dome during the 2006 and 2007 Antarctic summer field seasons. Primarily, the data consist of low-frequency radar data (2 MHz, approximately 50 meter resolution) in order to observe deep internal layers and the ice-bed interface. The data set also contains one file with high-frequency (100 MHz, approximately 1 meter resolution) radar data, for a sub-region of one of the low-frequency radar profiles. Coincident kinematic GPS data were also collected to correct the radar data for topography along each profile. Radar profiles are typically approximately 20 km in length with the grounding line crossed centrally where possible.

Data are available via FTP in Matlab (.mat) format.

摘要：本数据集涵盖2006年与2007年南极夏季野外考察期间，沿西普尔穹顶（Siple Dome）附近的冰架接地线区域开展地面观测所采集的冰穿透雷达（ice-penetrating radar）数据。数据集核心为低频雷达数据（2 MHz，分辨率约50米），用于探测深部内部冰层与冰床界面。此外，数据集还包含一份针对单条低频雷达剖面的子区域的高频雷达数据文件，其工作频率为100 MHz，分辨率约1米。同步采集的运动学GPS（kinematic GPS）数据可用于校正各雷达剖面沿程的地形偏差。雷达剖面长度通常约为20千米，且尽可能在剖面中心位置穿过冰架接地线。

本数据集可通过FTP协议获取，文件格式为Matlab（.mat）。
