Abstract:
Global informations about the Earth (such as its mass and its moment of 
inertia) can be extracted  from gravitational measurements. Propagation 
of seismic waves allow us to infer properties of the  crust, the mantle 
and the outer core. The inner core, however, cannot be tested directly, 
as seismic  waves cannot cross the liquid outer  core. Neutrinos can be 
used to measure the Earth's density profile by  means of electroweak  
interactions only, thus giving an independent  and complementary  
picture of the Earth. I will show the first sensitive neutrino Earth 
tomography result to date using one year of IceCube atmospheric 
neutrinos data, and discuss the future prospects
