The book "Oceanology (in engineering)" by G. Smirnova is a unique and fascinating study that opens to the reader the exciting world of oceans and seas, viewed through the prism of engineering sciences. This work will be a real discovery for those who are interested not only in natural phenomena, but also in how these phenomena can be used in engineering practice. In his book, Smirnov brilliantly combines scientific facts and engineering approaches, which makes the material accessible and understandable to a wide audience. Oceanology, as a science that studies oceans and marine ecosystems, encompasses many aspects, from the physics and chemistry of marine waters to the biology of marine organisms and the geology of the seabed. The author focuses on how this knowledge can be applied to solve urgent problems, such as environmental protection, the development of new technologies for resource extraction and the creation of sustainable systems for the operation of marine spaces. The book will be of interest to both students and graduate students studying engineering and natural sciences, as well as professionals working in the field of marine engineering, ecology and resource management. It will also attract the attention of readers interested in environmental issues and sustainable development, because Smirnov raises important questions about the impact of human activity on the oceans and the need to protect them. The topics covered in the book cover a wide range of issues, from climate change and its impact on sea level to technologies used to monitor the state of the oceans. Smirnov not only shares his knowledge, but also invites readers to think about how we can use this knowledge to create a safer and more sustainable future. The book makes you think about how important it is to take care of natural resources and how engineering solutions can help with this. Style G. Smirnov is distinguished by clarity and logical presentation, which makes complex concepts accessible to understanding. He masterfully uses real-life examples, which allows the reader to better absorb the material and see its practical application. Smirnov is also known for his other works, in which he explores various aspects of engineering and ecology, which confirms his status as an expert in this field. If you are looking for a book that will not only expand your knowledge of the oceans, but also inspire you to new ideas and solutions, “Oceanology (in engineering)” will be an excellent choice. This work will be a real guide to the complex but fascinating world of marine research, offering readers a unique opportunity to look at the oceans in terms of engineering and science. Do not miss the chance to immerse yourself in this exciting topic and discover new horizons of knowledge.
