The purpose of the article is to identify regional features of the Arctic States of the Eastern hemisphere. The Arctic region has enormous geopolitical and economic potential, and in the twenty-first century it is becoming one of the main objects of conflict of interests of the leading powers of the modern world. In their research, the authors used experimental-theoretical methods, as well as system analysis, logical and historical methods. The results of the analysis of the literature used, actual data, and research searches have shown that the key element in determining the region is its borders. There are many definitions of the Arctic, but due to the Northern features, none of them fully corresponds to the tasks of state regulation of territories. Along with the General assessment of the region and space, the article analyzes in detail various approaches to determining the borders of the Arctic region of all the countries participating in the Eastern hemisphere: Denmark, Russia, Finland, Sweden, and Iceland. A retrospective analysis of the existing definitions for a wide range is carried out. The conclusions summarize that among the Arctic countries, the astronomical approach in combination with the administrative and political definitions of the participating countries themselves prevails, which begins to form trends towards changing approaches to the Arctic as a whole.

Findlay Creek is a small, coldwater stream which was crossed by a natural gas pipeline using conventional open-cut techniques in late August 1992. Pipeline crossing activities included the removal of a beaver dam which was located along the proposed alignment, the installation of a temporary road crossing, and the actual pipeline installation. A monitoring study was initiated to examine the impacts of pipeline construction on this stream including changes in the physical and biological regimes of the aquatic ecosystem. Results of this study indicate that the dramatic sediment loads (suspended sediment levels of up to 3000 mg/L) caused by pipeline construction were sufficient to cause changes to the channel morphology as well as the fish and invertebrate communities. By twelve weeks post-construction, partial recovery of habitats and aquatic communities was apparent. Changes to the physical channel parameters and the stream population structure documented in this study suggest that impacts to Findlay Creek were localized, and full recovery was documented in affected areas by the one year post construction sampling period. This study concurs with other research investigating the impacts of pipeline construction, in that impacts on the aquatic fauna appear to be localized in extent and short term in duration.
