The data on engineering and ecologicall surveys on the land and sea sections of the gas pipeline “DzhubgaLazarevskoye-Sochi” are summarized for the years 2002–2008. They include geoecological testing and assessment of soil, subsoil, surface and groundwater contamination. Oceanographic surveys, sampling of water and bottom sediments, a complex of chemical and analytical studies of samples on shipboard and in stationary laboratories along the sea gas pipeline were performed. Special attention was paid to the study of heavy metals of the first class of hazard in the components of the natural environment. Some regularities of their distribution in the marine environment were revealed. The work performed in the coastal waters of the Caucasian coast elucidated that technogenic influence in this region is a factor that determines the geoecological situation on the shelf in many respects. The ecological and geological situation of the Black sea marine environment in the area of the gas pipeline has been assessed.

Keywords: the Black sea, shelf, gas pipeline “Dzhubga-Lazarevskoye-Sochi", engineering and environmental surveys, sea water and bottom soils, heavy metals and arsenic
