TALDICE-1 age scale of the Talos Dome deep ice core, East Antarctica
A new deep ice core drilling program, TALDICE, has been successfully handled by a European team at Talos Dome, in the Ross Sea sector of East Antarctica, down to 1620m depth. Using stratigraphic markers and a new inverse method, we produce the first official chronology of the ice core, called TALDIC...
