24 Radio Wish List? Pingers—Deployable--(air, water, ice interface) complicates optics. Permanent dedicated antennas at various depths. Special boreholes to 1000 meters. (both items are perishable opportunities which vanish when the IceCube string deployments stop. Ice Characteristics: Index, Absorption Lengths, with respect to temperature (depth), density, and frequency. Testbed—surface and meters deep, test firn-drill technology
