Usage the method of Human Impact Assessment (HIA) for estimation of coastal local municipalities allows evaluating the nature-ecological state / environmental situation of coastal local municipality, given an opportunity to show the hierarchy of municipalities and determining the HIA, vulnerability and opportunity for their future development. In the paper, the indicator method of HIA for estimation of coastal local municipalities and their main assumptions are formulated. Due to the HIA analysis, the list of factors of estimation of the nature-ecological state / environmental situation of coastal local municipality was obtained. For each selected factor the method of indicator value calculation, as well as computation of value of the integrative indicator of the nature-ecological state for coastal local municipality (or HIA estimation value for coastal local municipalities) as average of indicators, is proposed. Application of the method is considered for coastal local municipalities of the Leningrad Oblast and St. Petersburg. Based on the indicators and integrative indicator values the recommendations to reduction of human impact for coastal local municipalities are made.

The temporal structure of the iceberg hazard in the central part of the Barents Sea is studied. Using the concept of iceberg activity for risk-management purposes is suggested and the values to measur

Alternative routes of the Russian section of the Nord Stream 2 gas pipeline were studied using environmental criteria. The planned anthropogenic impact was assessed making use of a complex of biotic and abiotic parameters of marine ecosystems allocated in the zones of influence. On land the water protection zones and coastal protective strips of water bodies, specifically protected natural areas, cultural heritage sites, settlements' infrastructure and land transport routes were allocated. The offshore zone of the pipeline includes the navigable routes, anchorages, areas of dangerous navigation and limited access due to the Navy activities, areas of intersection with the existing marine infrastructure (cables and pipelines), fishing areas, areas of dangerous exogenous geological processes and hydrological phenomena (degassing of gas-saturated deposits, ice plowing of the bottom, erosion activity of bottom currents, slope and coastal processes). The results of environmental risk assessment for alternative versions of the Nord Stream 2 route (Russian section) in standard mode and in case of potential accidents are presented.
