The proposal seek support to measure the attenuation and reflection properties of the Ross Ice Shelf at radio frequencies between 100 MHz and 1 GHz in the vicinity of McMurdo Station. This information is vital to the development of the ARIANNA high energyneutrino concept, which utilizes the Ross Ice Shelf and requires a medium with low losses of radio signal strength due to absorption and good reflection from the ice-water interface. As with any detector that involves the use of a naturally occurring medium, its physical properties dictate the viability of the idea. Several potential sites for ARIANNA are identified and it is proposed to measure the ice electromagnetic properties at one or more of these locations. It is anticipated that final site selection for the tests will depend on detailed discussions with the Office of Polar Programs.

该提案寻求支持，以测量麦默多站附近罗斯冰架在100兆赫至1千兆赫无线电频率上的衰减和反射特性。这一信息对于发展阿里安纳高能中微子概念至关重要，该概念利用罗斯冰架，并需要一种由于吸收和冰水界面良好反射而使无线电信号强度损失低的介质。与任何涉及使用天然存在的介质的探测器一样，它的物理特性决定了这个想法的可行性。确定了几个潜在的地点为ARIANNA，并建议在这些位置中的一个或多个测量冰的电磁特性。预计测试的最终地点选择将取决于与极地计划办公室的详细讨论。
