Efforts of domestic and foreign scientists in Black sea execute huge volume of geologo-geophysical researches. Thus, always the special attention was given to studying of a bottom relief. The productive part of these works reflected in the published cartographical documents, monographies and numerous articles. Therefore, now we have possibility on bathymetric and to other charts of a seabed to receive general idea about various relief-forming processes. In this aspect, the special importance is acquired by detailed researches of a bottom relief on complex ranges with use of a wide spectrum of oceanographic methods. Based on materials of an echo sounding measurement of the different areas, made bathymetric, geomorphologic chart, schemes and survey profiles of a bottom relief, which can be a reliable basis for the further possible constructions. In given article observed a bottom relief and geomorphologic features of the Bulgarian range. Thus, the published data on seismoacoustic profiling, sampling of a bottom ground etc. were considered. In that case, repeated processing received before materials of an echo sounding measurement on a shelf, in aggregate with orography of an adjoining land, have allowed generalize and analyze in a bit different aspect a structure of a shelf and the upper part of a continental slope. Their binding border is the shelf edge, which formation and development occurred in close interaction of endogenous and exogenous relief forming factors. It is most visually shown in morphometric data of the shelf edge in a projection to a vertical plane. At such construction most accurately traced the neotectonics role in morphological transformation of an external zone of a continental shallow. Authors consider such method productive, perspective and evident. It can be used at the morphostructural analysis of extended forms of a relief: ridges, ledges, canyons and other forms subject to influence of vertical neotectonic movements.
