Na+ activity as measured in natural waters, humid soils and vegetation in the area around Fiskenæsfjorden (Qeqertarssuatsiait kangerdluat), southern West Greenland

Abstract

In order to gain some knowledge of the regional distribution of sodium and of the release of sodium from silicate rocks under sub-arctic conditions, Na+ activity has been measured by means of a selective glass-electrode on a variety of naturally occurring substances in the Fiskenæsfjorden area. The technique employed is rather similar to that used for pH measurements; results are therefore expressed as pNa, being the negative logarithm of the Na⁺ activity.
