Abstract

For the first time, the specific features of snow cover chemistry were studied in the period of its accumulation on Bolshevik Island (the area near the research station Cape Baranov Ice Base). In winter 2018/2019, the specific electric conductance, density, titrated acidity, pH, \({\text{NH}}_{4}^{ + }\), \({\text{NO}}_{3}^{ - }\), \({\text{NO}}_{2}^{ - }\), \({\text{PO}}_{4}^{{3 - }}\), and Si were measured in fresh and compacted snow and, additionally, Na⁺, К⁺, Ca²⁺, Mg²⁺, Cl⁻, and \({\text{SO}}_{4}^{{2 - }}\) were measured in compacted snow. Patterns of variations of fresh and compacted snow characteristics were identified, and the effect of marine and anthropogenic factors was discussed. Snow chemistry on Bolshevik Island was compared with the chemistry of precipitation and snow cover in other background areas of the Russian Federation.

高纬度北极地区积雪的化学特征：塞维利亚泽姆利亚群岛布尔什维克岛巴拉诺夫角

摘要首次研究了布尔什维克岛（巴拉诺夫角冰雪基地研究站附近地区）积雪覆盖层化学的具体特征。在2018/2019年冬季，比电导、密度、滴定酸度、pH值、\({\text{NH}}_{4}^{ + }\),\({\text{NO}}_{3}^{ - }\),\({\text{NO}}_{2}^{ - }\)、\此外，还测量了压实雪中的Na+、К+、Ca2+、Mg2+、Cl-和\({text{SO}}_{4}^{2 - }}。确定了新雪和压实雪特征的变化模式，并讨论了海洋和人为因素的影响。将布尔什维克岛的积雪化学与俄罗斯联邦其他背景地区的降水和积雪化学进行了比较。

期刊介绍： Water Resources is a journal that publishes articles on the assessment of water resources, integrated water resource use, water quality, and environmental protection. The journal covers many areas of research, including prediction of variations in continental water resources and regime; hydrophysical, hydrodynamic, hydrochemical and hydrobiological processes, environmental aspects of water quality and protection; economic, social, and legal aspects of water-resource development; and experimental methods of studies.
