THE EFFECT OF PRESSURE ON THE IONIC CONDUCTANCE THROUGH THE UPPER 2000 METERS OF THE OCEAN'S COLUMN.

Abstract

The specific conductivity of 5 different electrolytic solutions over a pressure range of 1 to 200 bars has been measured. The solutions were 0.01N, 0.10N and 1.00N KCl and 2 solutions of sea water. One sea water solution was real sea water, the other artificial. Each solution was tested at 4 temperatures, ranging from 4C to 18C. The pressure caused the specific conductivity of all solutions to increase in a non-linear fashion. First, second and third degree least square curves have been fitted to the data for comparisons. The specific conductivity caused by solution concentration changes during compression has been determined and found to be a significant error source. Explanations are offered to account for the conductivity changes considering the manner in which pressure alters the chemical structure of the solution. The areas discussed are solution concentration, applied voltage, interionic reactions and viscosity. (Author)
