Atmospheric neutrinos for investigation of Earth interior

The neutrino experiment IceCube at South pole can distinguish between Bulk Silicate Earth model and Hydridic Earth model predictions about inner Earth density by using neutrino absorption tomography. The result can be obtained during less than 10 years of operation. The experiment PINGU at South pole can check the Hydridic Earth model predictions about Earth core electron density by using neutrino oscillation tomography. The result will be obtained for the time of operation much shorter than 10 years. The combination of IceCube and PINGU results will give the information about the Earth core chemical element composition.
