“…As ice thickness in the Arctic rivers tends to decrease with ongoing climate warming (Vuglinsky and Valatin, 2018) and projected increasing snowfall (e.g., Callaghan et al, 2011), the proportion of serpentine ice to bedfast ice area will likely increase, resulting in increased winter water flow beneath the ice (Gurevich, 2009;Tananaev et al, 2016), positive mean annual temperatures at a greater area of the riverbed and consequent talik growth. Sensitivity analysis of the model used in our study shows that even 5 cm of snow on the river ice can reduce the ice thickness at the end of the season by up to 30 cm, affect the thermal properties of the sub-river sediment, and cause talik growth (Supplementary Figure S5).…”

Arctic deltas and their river channels are characterized by three components of the cryosphere: snow, river ice, and permafrost, making them especially sensitive to ongoing climate change. Thinning river ice and rising river water temperatures may affect the thermal state of permafrost beneath the riverbed, with consequences for delta hydrology, erosion, and sediment transport. In this study, we use optical and radar remote sensing to map ice frozen to the riverbed (bedfast ice) vs. ice, resting on top of the unfrozen water layer (floating or so-called serpentine ice) within the Arctic’s largest delta, the Lena River Delta. The optical data is used to differentiate elevated floating ice from bedfast ice, which is flooded ice during the spring melt, while radar data is used to differentiate floating from bedfast ice during the winter months. We use numerical modeling and geophysical field surveys to investigate the temperature field and sediment properties beneath the riverbed. Our results show that the serpentine ice identified with both types of remote sensing spatially coincides with the location of thawed riverbed sediment observed with in situ geoelectrical measurements and as simulated with the thermal model. Besides insight into sub-river thermal properties, our study shows the potential of remote sensing for identifying river channels with active sub-ice flow during winter vs. channels, presumably disconnected for winter water flow. Furthermore, our results provide viable information for the summer navigation for shallow-draught vessels.

“…The observed changes in the parameters of the ice regime on Lake Morskie Oko were typical of the vast majority of rivers and lakes of the northern hemisphere at the time (Anderson et al 1996;Kuusisto and Elo 1998;Magnuson et al 2000;Yoo and D'Odorico 2002;Huntington et al 2003;Marszelewski and Skowron 2006;Jiang et al 2008;Stonevicius et al 2008;Klavins et al 2009;Pawłowski 2017;Vuglinsky 2018). Regarding the start and end dates of ice phenomena and ice cover, more evident changes in the end dates (springtime) resulted from an exceptionally clear and statistically significant increase in the temperature in April and May, reaching up to 0.7°C per 10 years (Pociask-Karteczka and Choiński 2012).…”

“…Increasing winter temperatures are modifying the winter water regimes of rivers and lakes, as was distinctly manifested in the 20 th century, but also from the mid-19 th century (e.g. Magnuson et al 2000;Huntington et al 2003;Marszelewski andSkowron 2006, Jiang et al 2008;Stonevicius et al 2008;Klavins et al 2009;Takács et al 2012;Vuglinsky 2018). The ice season is becoming shorter and the maximum observed ice thickness is decreasing.…”

Changes in the course of ice phenomena on Morskie Oko in the Tatra Mountains from 1963 to 2012 and the implications for tourism

The article presents changes in the course of ice phenomena on Lake Morskie Oko over 50 years. It comprises detailed data of the course of the main parameters of ice regime of the lake in the years 1963–1970. Such a reference period yielded substantial differences in the obtained values of trends in comparison with the period 1971–2010, which is most common in literature. The trends obtained differed substantially from those describing the years 1971–2010, and the change in the parameters – scaled to a year of the analysed period – was about half the size. Attention was also drawn to the practical aspect of the changes in the duration and thickness of ice cover on the lake. In the years 1963–2012 the period of safe movement on the frozen lake was reduced by only 10 days.

“…Важным следствием текущей климатической изменчивости является сокращение периода ледостава и уменьшение толщины льда на озерах умеренной и арктической зон (Magnuson et al, 2000;Korhonen, 2006;Vuglinsky and Valatin, 2018;Sharma et al, 2019;Solarski and Rzętała, 2020). Тенденция сокращения продолжительности ледостава отмечена и на озерах Карелии (Efremova et al, 2013) и Финляндии (Korhonen, 2006).…”

This article investigates regularities of thermal and ice regimes of three small lakes of Karelia under current climatic conditions. Data of measurements of water temperature at autonomous stations and results of numerical calculations of the dates of ice-on and ice-off and the thickness of ice in these lakes using the one-dimensional parameterized model FLake in the anomalously warm winter season of 2019-2020 are analyzed. Data obtained are compared with long-term values over 1994-2019. The dates of the ice-on and ice-off on the lakes were quite close; however, on two larger lakes, intermediate ice destruction was observed at the beginning of winter, due to which the duration of the ice season differed between lakes by two weeks. The winter months of 2019-2020 were 6.4-9.4 ° C warmer than the baseline, which was reflected in a noticeably smaller ice thickness on the lakes compared to previous years of measurements (40-48 cm at the end of March 2020 compared to the values in mid-April in 1994-2004 - 65-85 cm and in 2005-2018 - 50-65 cm). The decrease in ice thickness contributed to an early onset (mid-March) and long duration (more than five weeks) of spring subglacial convection. The model calculation, taking into account the atmospheric impact based on the ERA-5 re-analysis, reproduced the main features of the ice regime of the lakes, including the intermediate destruction of ice at the beginning of winter on two larger lakes. Significant regression relationships have been obtained between the dates of ice-on and ice-off on Lake Vendyurskoe, the dates of the onset and duration of spring under-ice convection, and the characteristics of the regional climate of southern Karelia (air temperature and the number of days with thaw in winter and spring months) for 1994-2020. The relationship between the dates of ice-on and the water temperature in the lake in winter is shown.
