Natural features of the development of the licensed areas of Surgutneftegaz OAO in the Nenets Autonomous District of Arkhangelsk Region

Authors: A.Yu. Solodovnikov, A.M. Soromotin (Tyumen Branch of SurgutNIPIneft)
The stability of tundra ecosystems of the Nenets autonomous district within seven license areas of Surgutneftegaz OAO is considered. The results of ranking of tundra ecosystems by the resistance to mechanical stress are given. Data of investigations of the current background level of pollution of surface water, sea-floor sediments and soils are presented. It is concluded that the pollution of surface waters and soils can be caused not only by anthropogenic impacts, but also natural factors; pollution of sea-floor sediments does not exceed permissible levels.
