Regional distribution of chemical tracers in snow cover along the route from S16 to Dome Fuji Station, east Dronning Maud Land, Antarctica
We show and discuss the regional distributions of Cl^-, Na^+, SO_4^2,NO_3 and ^7Be concentrations in snow cover along the route from S16 to Dome Fuji Station in east Dronning Maud Land, Antarctica. The concentrations of Cl and Na^+ at the coast exponentially decreased with distance from the coast up...
