Aeromagnetic survey by small unmanned aerial vehicles and plate tectonics of Bransfield Basin in Antarctica

利用小型无人机在南极洲布兰斯菲尔德盆地进行了航磁测量。磁异常是在欺骗岛北半部获得的。这是第一次成功的此类冒险，证明了无人机的空中调查对南极研究调查是有用的。航空测量提供了一种安全、经济的数据采集方法。在乔治国王岛进行了岩石磁学、地质年代学和磁测量研究。结果表明，布兰斯菲尔德盆地具有典型的弧后盆地地质构造特征。

Aeromagnetic survey by small unmanned aerial vehicles (UAV) was carried out at Bransfield Basin, Antarctica. The magnetic anomaly was obtained from the northern half of Deception Island. That was the first successful venture of this kind, demonstrating that airborne surveys by UAV are useful for Antarctic research investigations. Airborne surveys provide a safe and economical approach to data acquisition. Study of rock magnetism, geochronology and magnetic survey was conducted at King George Island. The results showed that Bransfield Basin was formed with a typical characteristic of geological structures of back-arc basin.
