A method based on the application of the iodine-131 isotope was used for investigation of turbulent diffusion in the sea. A special appratus constructed for the purpose in 1956 was utilized for measurements conducted in the Black Sea on the basis of which the numerical values of turbulent diffusion factors were determined. The tracers were observed with the aid of recorders consisting of Geiger-Muller counters which made it possible to determine the concentration of radioactive element in a definite solid angle. The operation of the appratus is illustrated by graphs and the methods of recording calculation and verification of the results are elucidated by mathematical formulae based on tests.
