Measurement of natural particulate fallout onto high polar ice sheets

The paper describes specifications for the laboratory, the purification of tap water for use as wash water and in making moderately clean NaCl solutions, the cleaning of glassware, the preparation and cleaning of NaCl solutions, the processing of ice samples, the measurement of electrical conductance, the Goulter particle counter and its use, and some of the underlying principles. The equipment used is identified and some first results obtained on cores from Byrd Station, Antarctica, are presented. (Author).
