“…Since the winter of 1978-1979, the satellite data is used to determine the characteristics of the ice cover and to identify ice features 1 . Since the beginning of the 2000s, the exploration and development of oil deposits on the Caspian shelf caused detailed studies of the stamukhi parameters, grounding process, internal structure (Mironov, Porubaev 2005) and their effect on the seabed (Nepomenko, Popova 2018), modeling (Andreev, Ivanov 2012) and detailed ice monitoring (Frolov et al 2009). Later Ogorodov and Arkhipov (2010) deteceted the impact of stamukhi and ice ridges on the seabed at depths of up to 12 m using slide-scan sonar survey.…”

The Caspian Seaseasonal ice cover develops each winter despite of it being in mid-latitudes. Increasing development of oil and gas fields challenges researchers to ensure operational safety. TheCaspian Seahas seen significant water level fluctuations in its recent history. And in the same time, it is vulnerable to effects of climate change. Extensive studies on ice conditions conducted in the region don’t provide insights on influence of these factors in combination to describe ice cover behavior and ice features distribution. We classify winter seasons of theNorthern Caspianby their severity calculating the cumulative freezing-degree days (CFDD). Ice charts based on aerial reconnaissance with support of the OSI-450 reanalysis provided data on the ice coverage, the timing of ice formation and destruction, the duration of the ice seasons from 1979 to 2015. We analyzed the stamukhi distribution on theNorthern Caspianfrom aerial reconnaissance for 1973–1980 and satellite imagery deciphering for 2013–2019 periods along with sea level dynamics. We found out that the amount of severe and moderate winters reduces while mild winters number increases. This leads to a decrease in the mean ice area and ice duration at theNorthern Caspian. Comparison of two periods with different sea levels and ice coverage showed that both factors affect the distribution of stamukhi by depth and distance to coast in theNorthern Caspian. Comparison of stamukhi locations in moderate winter seasons showed that their distribution is determined by the area of ice cover. In case of similar ice conditions, the stamukhi distribution is determined by sea level. The zone of their highest concentration shifts along with the coastline offset.

“…Past studies on Caspian sea-ice include investigations of sea-ice ridging, rafting, ice pile-up and hummocks through modelling and observations (Frolov et al, 2009;Bailey et al, 2010;Klyachkin, 2011;Andreev and Ivanov, 2012). Ocean and atmospheric variables of the Caspian have also been modelled with sea-ice used as a boundary condition (Ibrayev et al, 2009;Syed et al, 2010;Semenov et al, 2012;Kitazawa and Yang, 2012).…”
