Detection of a waveguide in the basement of the northwestern shelf of the Black Sea according to the results of reinterpretation of the DSS materials of profiles 26 and 25

Detection of a waveguide in the basement of the northwestern shelf of the Black Sea according to the results of reinterpretation of the DSS materials of profiles 26 and 25

Results of reinterpretation of DSS materials along the profiles worked out within north-western shelf of the Black Sea near 45 years ago are given. Those are two seismic profiles crossed the shelf area: latitudinal DSS Profile 26 (Zmiyinyi Island - Tarkhankut Peninsula) and Profile 25, which crosses...
