Abstract An isotope–geochemical study was performed on the waters of Abrosimov and Stepovoi bays along the southeastern coasts of the Novaya Zemlya Archipelago. The waters considered were freshened by several sources: the continental river runoff, the regional atmospheric precipitation, and the waters supplied from the archipelago. The contributions of these freshwater constituents appeared to be different for surface and subhalocline waters. It was shown that the surface waters were freshened with the local runoff from the archipelago, whereas those situated under the halocline were affected by a mixture of the Ob and Yenisei waters along with thawed riverine ice. The supply of the constituents mentioned into aquatic areas of the bays was determined by the global circulation of the Kara Sea waters freshened in turn with those of the continental runoff as well.

根据同位素(δD, δ18O)资料研究新地群岛尤日尼岛海湾淡水资源

摘要 对新地岛群岛东南海岸的 Abrosimov 和 Stepovoi 海湾水域进行了同位素地球化学研究。所考虑的水域通过多种来源进行了清新:大陆河流径流、区域大气降水和群岛供水。这些淡水成分的贡献对于地表水和亚盐层水似乎不同。结果表明,地表水因来自群岛的当地径流而变得清新,而位于盐层之下的水则受到鄂毕河和叶尼塞河水以及融化的河流冰的混合物的影响。
