- Аннотация: Veniamin Fedorovich Perov, who was a researcher at the Khibiny Station of the Faculty of Geographyof Moscow State University, discovered very small glaciers in Khibiny Mountains in 1958. He described four glaciers. They were not studied until 2005, when our research began. We used field observations, drilling, GIS, and remote sensing methods to ascertain the glacier structure and estimate the change in their geometry for 60 years. Snow-ice formations were drilled through, ice cores were collected, and geochemical and isotope-oxygen analyses were performed for the first time. The thickness of the ice cores varied from 0.2 to 1.6 m. Our research has shown that the glaciers remain relatively stable in area despite a weak trend toward shrinkage. According to the analysis of climate changes in the Khibiny Mountains, the snowfall decreased there in theearly 2000s; the maximum snow thickness at the meteorological site of the Khibiny station was 55 cm in the winter of 2002/2003. This may be the cause of the shrinkage of the glaciers by more than two times during these years. However, the snowfall increased after 2007. A snow thickness maximum of 180 cm was recorded in 2020, which was the maximum value over the observation period (1984–2020). According to the literature data, the annual average temperature on the plains of the Kola Peninsula has attained 2.3 ± 1°C over the past 50 years; however, the warm-period average temperature has not increased. We believe that this fact, along with the increase in the snowfall amount in recent years, determine the quite stable state of snow-ice formations in the Khibiny, which are more resistant to global warming than mountain glaciers.
