“…The observed oscillation in the sea ice coverage can be explained by changes in the severity of different winters during the period of this study (Kouraev et al, 2004). The dependence of the ice regime to the air temperature was also shown in other studies (e.g., Baklagin, 2019). A gradual west/southwards gradience was observed in the time of the sea ice formation in the NCS.…”

To understand the spatial and temporal variations in the extent and timing of sea ice in the Caspian Sea (CS), 15 years of sea ice presence and its phenology (freeze-up, break-up, and duration) were studied in the Northern CS (NCS) for a period from 2004 to 2018. This study indicated that the percentage of sea ice covered area in the CS showed fluctuations ranging from 54.2% in 2004 to more than 89% in 2006 and 2008. This study, furthermore, found regional differences within the NCS in sea ice phonological features during 2004 to 2018. Specifically, earlier sea ice formation, later ice melt, and longer ice periods were observed in the eastern than the western NCS. Noticeable interannual changes were also observed in the timing and duration of the NCS ice (2004-2018). However, most parts of the NCS did not show significant trends (P>0.05) in the formation, decay, and duration of sea ice and their interannual variability. The observed spatial and temporal patterns in the CS ice can have implications for phytoplankton blooms and higher trophic levels, such as fish and endangered Caspian seal populations and merits further investigation.

The paper presents the spatial and temporal regularities of the course of ice processes in the White Sea, derived from satellite data observations for the period 2004-2020. The dependences, defining indicative dates of the White Sea ice regime of air temperature regime over its water area are given, which can be used for diagnostic and prognostic purposes. It is noted that the connection with the Barents Sea has a significant impact on the course of the ice regime of the White Sea, in particular, on the beginning freeze-up phase and the beginning break-up phase. Comparative analysis of seasonal variations in ice coverage in the White Sea indicates that the course of the ice regime in recent years generally corresponds to how it happened in the second half of the XX century, however, a decrease in average values of ice coverage by 3-7% was recorded throughout the entire period of ice phenomena, which is in line with the global warming trend. Also, the results of the effects of abnormally warm winter on the formation of the White Sea ice regime of 2019-2020 are presented.
