The dynamics of the development of the Lena polynya forming in the Laptev Sea and its impact on navigation conditions in the Arctic, in the Laptev Sea, is investigated. The hypothesis is tested that the timing of polynya may have a significant impact on its average growth rate. The results of the GLORYS12v1 global reanalysis and standard methods of mathematical statistics were used in this test. The validity of the hypothesis was confirmed by the example of the section of the polynya located at the mouth of the major navigable channel of the Lena delta Bykovskaya. Stable tendencies of changing the dates of the polynya formation towards earlier dates in the modern period have been revealed. A high probability of improvement of navigation conditions is observed in this region in 2020-2040. However, with further warming of the Siberian climate, the opposite process is possible - the freezing of the polynya that formed too early, which will lead to a colder climate in the region and deterioration of navigation conditions. The selection of general routes for ships in the areas where the polynya is spreading will contribute to more intensive and safer navigation. For this purpose, accurate forecasts of its size and position are required. The relevance of research results for ship traffic forecasting and plans for the use of icebreaker escorts for vessels is noted.

The paper considers the problems and features of the functioning of the energy complex in the regions of the Russian Arctic under the influence of global climate change. Particular attention is paid to new ideas and developments intended for practical use in developing measures to adapt to the adverse effects of climate change. The issues of optimising the composition and structure of the energy economy of the Arctic territories in the areas of permanent residence, reducing the burden on natural ecosystems, and risks in the field of sustainable economic and social development of the Arctic region are discussed. The ways are proposed for developing new approaches to the formation of a strategy for the development of the region’s energy infrastructure under the influence of climatic and environmental factors on the natural environment. The mechanisms of the impact of changes in the climatic characteristics of the region on the operating conditions and the efficiency of energy facilities of the fuel and energy complex are determined. The degree of this dependence was studied for different types of infrastructure facilities of the fuel and energy complex. The data on the assessment of the impact of global climate change on the infrastructure of the fuel and energy complex and the possibilities for its adaptation, which include: the implications for power generation facilities; impact on energy transportation; problems of thawing permafrost and solifluction; climate impact on energy consumption and socio-economic effects; the role of distributed energy and renewable energy in adaptation to climate change. It is shown that for the territories of the Russian Arctic with isolated energy supply, the development of energy-efficient systems and renewable energy will reduce climate risks for sustainable growth. Not only of this power sector but the whole economic complex of the region due to both their better adaptation to the effects of climate change and the reduction of technogenic greenhouse gas emissions, which are one of the main factors of these changes.

The movement of icebergs in the Laptev Sea off the coast of the Severnaya Zemlya archipelago in spring of 2018 was analyzed using satellite observations in visible spectral band. As is shown in the article the data of radiometers installed on the Landsat-8 and Sentinel-2 satellites allow monitoring of iceberg drifting in spring period in the above Arctic region. Thus, in March-April 2018, the total amount of icebergs detected near the archipelago was 4917. 4161 icebergs were in the landfast ice, 722 ones were drifting with the ice fields, and the other 32 were aground in ice fields. The average length of the icebergs was equal to 88 m; the largest of the recognized icebergs was located in the landfast ice near the ice shelf of the Matusevich fjord and it was 1240 m in length. The maximum speed of drift of the icebergs, as determined by the satellite data, was equal to 29.5 km/day. This was estimated for the situation when the speed of the near-water (surface) wind reached 20 m/s and larger. The purpose of the work was to study drifting of icebergs in order to define more exactly dynamics of the iceberg movement in this poorly known area of the Arctic. It is found that in a case of the consolidated ice cover the drift speed of ice fields with the icebergs involved depends on the driving wind force and direction. According to mean speeds of movement all icebergs were separated into three groups: the icebergs of the coastal zone with velocities smaller 1 km/day; the icebergs of the transition zone at speeds of 1.3 to 1.6 km/day; and the icebergs of the transit zone with speeds larger 2 km/day. The characteristics of the iceberg drifts obtained on the basis of daily satellite monitoring can be used in regional iceberg drift models to ensure safe economic activity on the Arctic shelf. Also, they can find application in engineering calculations in the design of infrastructure facilities on the shelf of the Arctic seas.
