Processed ice shelf base picks from airborne radar depth sounding across the Pine Island Glacier Ice Shelf (2010-2011)

In 2011, aerogeophysics data were acquired over Pine Island Glacier, West Antarctica on a grid comprising 30 transverse lines across the glacier, each around 20 km long, and with a spacing of roughly 500 m between the lines. The orientation of the lines was selected to be perpendicular to the surface features visible in satellite images in the central part of the ice shelf. Elevation of the ice‐surface directly beneath the aircraft was simultaneously measured using a nadir‐pointing laser altimeter. We present here the processed bed elevation picks from airborne radar depth sounding collected using the BAS PASIN radar system. Data are provided as XYZ ASCII line data.2011年，科研人员在西南极洲派恩岛冰川（Pine Island Glacier）布设测网开展航空地球物理数据采集工作，该测网包含30条横跨冰川的横向测线，单条测线长度约20千米，测线间距约500米。测线方位选取为垂直于冰架中部卫星影像中可见的地表特征。同时，采用天底指向激光测高仪同步测量了飞机正下方的冰面高程。本数据集提供了基于BAS PASIN雷达系统采集的航空雷达冰厚测深数据经处理后得到的冰床高程拾取结果。数据以XYZ格式ASCII行数据形式提供。
