Beschreibungen/Notizen

• 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.
