The book “The weighted substance of the White Sea and its granulometric composition”, created by the team of authors, is a unique study that immerses the reader in the world of marine science and ecology. This publication will be especially interesting to those who are fond of oceanography, ecology, geology and biology of the seas. It is suitable for both undergraduate and graduate students, as well as professionals working in the field of marine research. The book focuses on the White Sea, a unique body of water that plays an important role in the ecosystem of Northern Europe. The authors carefully examine the composition of the suspended substance that is in the water and its granulometric composition, which allows a deeper understanding of the dynamics of the marine environment and its impact on biological processes. This study not only expands our knowledge of the White Sea, but also raises important questions about the state of the environment and the changes occurring in marine ecosystems. The book begins with an introduction to the geographical and climatic features of the region, which helps the reader to better understand the context of the research. Then the authors move on to methods of data collection and analysis, which makes the text not only informative, but also practical. Readers will be able to see how the research was conducted, what technologies were used and what conclusions were made on the basis of the data obtained. This makes the book useful not only for theorists, but also for practitioners working in the field of ecology and environmental protection. The topics raised in the book address not only scientific aspects, but also broader issues such as the impact of human activities on marine ecosystems, climate change and its implications for marine life. The authors emphasize the importance of sustainable resource management and the need to protect unique ecosystems such as the White Sea. This makes the book relevant and important for anyone interested in environmental issues. The style of the authors is characterized by scientific rigor and accessibility of the presentation, which allows the reader to easily assimilate complex concepts. The book is replete with graphs, tables and illustrations, which makes the material more visual and understandable . The team of authors consists of experienced researchers and scientists, which gives the work additional value and authority. Among other well-known works of the authors are works devoted to the ecology of other seas and oceans, which emphasizes their experience and deep knowledge in this field. This book will be an excellent addition to the library of anyone interested in marine sciences, ecology and environmental protection. It can be useful for both students and professionals working in the field of marine research, as well as for anyone who wants to better understand how marine ecosystems function and what challenges they face in the modern world. If you are looking for a book that will not only expand your knowledge of the White Sea, but also make you think about the future of our planet, then the “Weighed Matter of the White Sea and its granulometric composition” is exactly what you need. Do not miss the opportunity to immerse yourself in the fascinating world of marine research and learn more about how we can preserve unique ecosystems for future generations.
