Spatial variability of chemical tracers in surface snow along the traverse route from the coast to 1000 km inland at east Dronning Maud Land, Antarctica
We measured the spatial variability of Cl(-), Na(+), SO(2-)4, NO(-)3 and (7)Be concentrations in snow cover along the traverse 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...
