Processed line aeromagnetic data over the Recovery Lakes region and interior Dronning Maud Land, East Antarctica (2013)

Long-range airborne geophysical measurements were carried out in the ICEGRAV campaigns (2010-2013), covering hitherto unexplored parts of interior East Antarctica and part of the Antarctic Peninsula. The airborne surveys provided a regional coverage of gravity, magnetic and ice-penetrating radar measurements for major Dronning Maud Land ice stream systems, from the grounding lines up to the Recovery Lakes drainage basin, and filled in major data voids in Antarctic data compilations.We present here the processed line aeromagnetic data collected using scintrex cesium magnetometers mounted on the BAS aerogeophysical equipped Twin Otter. Data are provided as XYZ ASCII line data.本数据集依托ICEGRAV科考计划（2010-2013年）开展长距离航空地球物理测量，覆盖了迄今尚未勘探的南极东部内陆区域以及南极半岛部分区域。本次航空测量覆盖了毛德皇后地 (Dronning Maud Land) 主要冰流 (ice stream) 系统的重力、磁法及冰穿透雷达数据的区域范围，测量区间从冰架接地线延伸至复苏湖 (Recovery Lakes) 流域，填补了南极地球物理数据汇编中的主要数据空白。本次公开的为经预处理的航线型航空磁测数据，其采集工作由搭载于英国南极调查局 (British Antarctic Survey, BAS) 航空地球物理改装型双水獭 (Twin Otter) 飞机的斯坎特雷克斯 (Scintrex) 铯磁力仪 (cesium magnetometer) 完成。数据集以XYZ格式ASCII航线数据文件形式提供。
