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.
