Application of the Method of Ion-Selective Electrodes in Exploration Work on the Sea Shelf

Summary The paper provides information on the application of the method of ion-selective electrodes in geological exploration on the sea shelf. Currently, much attention is paid to the search for hydrocarbons in marine areas. In this regard, the authors propose a measurement method with paired, spaced electrodes of the "same name" (Cu-Cu), similar to the method of measuring the EP gradient (natural electric field). Ion-selective electrodes are able to respond to the concentration (activity) of the main ions in complex solutions in the presence of other ions. The paper presents the main problems of using this method, found a number of solutions associated with these restrictions and described further prospects for the development of this method.
