From existing methods of studying of a relief of a bottom in the seas and oceans are most widely applied: a regional echo sounding (on extended transitions between oceanographic stations) and work on detailed ranges. On rather small areas (from first hundreds to several thousand km2) complication and a variety of forms of a bottom surface, a variety of lithological formations and bedrocks gives the chance to define researches. In produced article results of researches of a relief of a bottom on two differently-great ranges of a northwest part of Black sea are described. At repeated processing of primary materials of an echo sounding corrective amendments in earlier compounded bathymetrical and geomorphological maps are introduced. Survey sea-bottom profiles are resulted. These materials in aggregate with the published geologo-geophysical data demonstrate that heterogeneity morphostructures in the studied area was formed with the assistance of several difficult interreacting relief-formation processes
