The White Sea System . T. 3. Scattered sedimentary material of the hydrosphere, microbial processes and pollution”, created by the team of authors, is a unique and in-depth study devoted to the ecology and hydrology of the White Sea. This third volume is part of an extensive project that covers diverse aspects of the ecosystem, and addresses critical issues relating to sedimentary materials, microbial processes, and aquatic pollution. The book analyzes in detail the processes taking place in the hydrosphere and their impact on the ecosystem of the White Sea. The authors investigate how scattered sedimentary material interacts with microbial communities, as well as how these interactions can be disrupted as a result of anthropogenic exposure.. The reader will be able to learn about how pollution arising from economic activities affects the biological diversity and health of marine ecosystems. This study not only deepens our understanding of the complex interrelationships in nature, but also raises important questions about the conservation and sustainable development of marine resources. The book will be of interest to a wide range of readers: from undergraduate and graduate students studying ecology and hydrology, to professionals in the field of environmental protection and biology. It will also attract the attention of researchers working in the field of marine ecology, and anyone interested in the problems of water pollution and the conservation of natural resources. The age category of readers is not limited here, since everyone who seeks to understand the complex processes occurring in nature will find something useful and fascinating in this book. Topics raised in the book are relevant and important in light of contemporary environmental challenges. Considering microbial processes, the authors emphasize their importance for maintaining ecosystem sustainability and the health of marine life. In the face of global climate change and increasing anthropogenic pressures on nature, such studies are becoming especially important. The White Sea System can serve as a basis for further research and discussion on how we can minimize negative impacts on the environment and preserve unique ecosystems. The style of the authors is distinguished by scientific rigor and accessibility of the presentation, which makes the material understandable and interesting for a wide audience. Each section of the book is filled with relevant data and examples, which allows the reader not only to immerse himself in the topic under study, but also to see its practical application. The previous volumes of the series have already touched upon important aspects of ecology and hydrology, and the third volume continues this tradition by deepening knowledge about the White Sea and its ecosystem. If you are looking for books on ecology, hydrology or marine research, then the White Sea System T. 3" will be a great addition to your library. It will not only enrich your knowledge, but also inspire further research and care for our planet. Read, explore and discover the amazing world that lurks beneath the surface of the waters of the White Sea!
