Summary
In this paper, we examine the character of non-uniqueness in the conductivity modelling problem for a spherically symmetric earth in order to show that methods, for determining upper and lower bounds on the possible range of values for electrical conductivity as a function of depth, must be developed before a better picture of conductivity within the earth can be obtained.
