Electroconductivity of fallen and drifting snow at Syowa Station, Antarctica
Samples of fallen snow, drifting snow and deposited snow were obtained at Syowa Station from April 2003 to October 2006. Electroconductivity of the meltwater was measured. The electroconductivities of the samples for the fallen snow under weak wind condition were mostly below several tens of μS cm,...
