The proposal seeks the logistical support to install and operate an ELF/VLF receiver system on the USAP's ship "Nathaniel B. Palmer" for measuring whistler "one-hop" signals injected in the Earth's magnetosphere by the High-frequency Active Auroral Research Program (HAARP) ionospheric heater facility, funded by the Office of Naval Research and deployed in Gakona Alaska. During its annual austral summer traverses between Christchurch and McMurdo Station, "Nathaniel B. Palmer" passes through a region that is geomagnetically conjugate to the HAARP location. During the ship's traverses through the ~300-km long conjugate area (at ~1000 km south-east of New Zealand), the HAARP facility in Alaska will operate at full-power, launching ELF/VLF waves into the magnetosphere, which then propagate along the geomagnetic field lines to the southern hemisphere, being amplified along their wave due to cyclotron resonance interactions with energetic electrons of the magnetospheric plasma. The intellectual merit of the proposed program lies in the importance of understanding how the artificially-induced magnetospheric waves might trigger particle emissions and loss processes from the Earth's radiation belts, both during quiet and geomagnetically disturbed periods. The broader impacts resulting from the proposed activity will include better understanding of energetic electron radiation in near-Earth space, which is detrimental to electronics on orbiting satellites, and the possible mitigation of effects of high-energy radiation via wave-particle interactions.

该提案寻求后勤支持，以在USAP的船舶“Nathaniel B”上安装和操作ELF/VLF接收器系统。Palmer”，用于测量高频主动极光研究计划（HAARP）电离层加热器设施注入地球磁层的哨声“单跳”信号，该设施由海军研究办公室资助，部署在阿拉斯加州的Gakona。在一年一度的南半球夏季穿越基督城和麦默多站之间，“纳撒尼尔B。帕尔默”通过一个地区，是地磁共轭的HAARP位置。在飞船穿越约300公里长的共轭区域（位于新西兰东南约1 000公里处）期间，阿拉斯加的HAARP设施将以全功率运行，向磁层发射极低频/甚低频波，然后这些波沿着地磁场线传播到南半球，由于回旋共振与磁层等离子体的高能电子相互作用，这些波沿沿着被放大。拟议方案的智力价值在于了解在平静期和地磁扰动期，人工诱发的磁层波如何可能触发地球辐射带的粒子排放和损失过程。拟议活动产生的更广泛影响将包括更好地了解近地空间高能电子辐射，这对轨道卫星上的电子设备有害，以及可能通过波粒相互作用减轻高能辐射的影响。
