“…The method was tested under semi-natural conditions. In case of real freezing on the underlying surface, the freezing time also includes the time of flooding, spreading over the ice surface, the time of water cooling to the crystallization temperature, the time of solidification and the time of cooling of newly frozen ice or its cold accumulation [7][8][9][10].…”

In the domain of hydrotechnical structures, novel methods are emerging to increase ice thickness, notably in the context of ice islands. The layer-by-layer freezing process serves as a cornerstone, where freezing time determines efficacy. The article explores diverse freezing techniques, their stages, and implications. Layer-by-layer freezing entails water pouring, followed by freezing after each layer. Augmentations involve introducing ice rubble and inclined plane freezing. Sprinkling accelerates freezing through water droplet adhesion. The block method uses extracted ice blocks, creating vertical surfaces without formwork. Volumetric freezing involves pipelines and refrigerants. One method blends ice rubble with additives for versatility. Combined methods expedite construction, especially for substantial projects. These techniques cater not only to ice island creation but also to temporally reviving deteriorating structures such as moorage contractions.

“…The Arctic Sea Route, often referred to as the Northern Sea Route, has long remained shrouded in a frozen silence, a pristine expanse of ice and cold, largely impassable for all but the most robust icebreakers and adventurers. Calculation of ice load become a special subject, and evolve a lot in recent years [1][2][3][4]. Yet, in recent years, this icy realm has undergone a staggering transformation, heralding a new era in both the geopolitical landscape and global commerce.…”

The Arctic Sea Route, also known as the Northern Sea Route, is experiencing profound changes due to the effects of climate change. This transformation is opening up new economic opportunities and geopolitical challenges, all while raising significant environmental concerns. The diminishing sea ice, thinning ice cover, and the development of new routes have reduced shipping distances, making this once largely impassable region increasingly accessible for global commerce. Economic implications include reduced shipping distances, expanded trade opportunities, and the potential for resource extraction, particularly for oil, gas, minerals, and fisheries. Geopolitically, the region is witnessing a complex interplay of cooperation and competition among Arctic states, with implications for international relations and territorial claims. Environmental risks, such as oil spills and habitat disruption, are significant, while infrastructure development and technological advancements are reshaping the logistics of Arctic navigation. The Arctic Sea Route's future hinges on how the international community addresses these multifaceted impacts, striking a balance between economic interests, environmental preservation, and peaceful cooperation in the face of shifting global dynamics and the urgent need to combat climate change.

“…The Arctic, a region of ecological significance, is undergoing a profound transformation as a result of climate change-induced shifts in its ice dynamics. This transformation, marked by unprecedented reductions in sea ice extent, thickness, and multi-year ice, underscores the urgent and far-reaching consequences of global warming on this delicate polar environment [1][2][3][4][5][6].…”

The Arctic, a region of ecological and climatic significance, is undergoing unprecedented ice changes due to climate change. This transformation, marked by rapid reductions in sea ice extent, thickness, and the persistence of multi-year ice, has far-reaching consequences for ecosystems, biodiversity, and global climate patterns. This article examines the historical perspective of the Arctic's ice dynamics, revealing a oncestable environment now in the throes of rapid change. The current state of Arctic ice is analyzed, emphasizing alarming reductions observed through satellite imagery and the implications for rising sea levels and disrupted ecosystems. Rooted in the causes of Arctic ice changes, primarily driven by the greenhouse gas effect, the article underscores the urgent need for global mitigation efforts. Scientific research and models provide critical insights, enhancing our understanding of the complex interactions driving these changes. Mitigation and adaptation strategies are discussed as essential components of a holistic approach, emphasizing the interconnectedness of the Arctic's fate with global efforts to address climate change. The exploration of Arctic ice changes serves as a call to action for international collaboration, sustainable practices, and a shared commitment to preserving the delicate balance of our planet's climate.
