This book written by famous scientist and professional astronomer J. B. Zirker is dedicated to the ocean waves, including tsunamis, stormy ocean waves and ripples, and the book is aimed at any interested persons including surfers and ocean scientists. The book is very hard to put down. It presents a very fascinating reading for them and is considered a great one for the oceanography classes, especially at undergraduate level.

The author has provided an up-to-date and quite comprehensive account of the matters whose complexity is commonly very hardly appreciated by non-professionals in the field and non-scientists. The deep insights, comprehensive narratives and historic perspectives included to the publication do not contain any single equation and presence of graphics has been kept to a minimum, making the volume very reader-friendly and being the reason why the title has been recognized as a very remarkable achievement.

We would say that this book may already be used as a standard textbook for the ocean as well as weather forecasters, scientists, plus climate modelers and students. The author has applied a very fresh look to the ocean waves and also provided the theory with numerous illustrations to make the content more accessible for everyone.

The book opens with the introductory chapter providing some general information, followed by the chapters that have been dedicated to the movement of the sea water and plants forming the plankton. Then there are several chapters dealing with the seasons at sea, various animals of the plankton etc. Separate chapters have been included addressing the vertical migration, marine life in the sea depths, photophores, fisheries and other aspects.

Numerous plates are there at the end of the title, including both black-and-white and color, accompanied by the comprehensive glossary of terms that have been used throughout the document. The author, A. Hardy, has expressed his wish to draw the careful attention of the readers of this volume, especially of non-professionals and non-scientists, to the glossary, because of the simple, concise and easily understandable explanations of the specific terminology that the author had to use.

Talking about the zoologists, the author would like to emphasize that the book will be very useful due to the amount of the information that is very difficult to find in other publications. That is the reason why this volume is so popular among the people involved in the field of marine science and we recommend it to everyone.

As it is clear from the title, the book is dedicated to the ecology of the sea shores. It has been specifically designed to be used by the students at graduate students as well as the students at upper-graduate level plus the professionals who are engaged in the management and research  related to the coastal zones.

The content of the book has been arranged in seven parts; the first part provides readers with some introduction to the ecology of the sea shores, and it also sets the scene for the remaining chapters of the publication. The second chapter of the book is dealing with the zonation patterns and the basic causes, together with the key components of the marine fauna, special habitats and other relevant matters.

The following chapter is covering the physicochemical environment and general biota. Then, there are two large sections of the volume dealing with the microbial ecology, detritus and nutrient cycles in the eco-systems in question. The remaining parts of the title address the existing ecological niches , maintenance/establishment of various zonation patterns, predation, disturbance and other factors determining the distribution and diversity, plus production of consumers, energy flow and flood webs, examples of the models of ecosystems, new network analysis techniques, comparison of the ecosystems etc.

We know that humans have influenced the environment in many ways in the past, but since the industrial revolution and even more during the "great acceleration in the human enterprise" following World War IT, humans have assumed the role of a dominating force in changing the biosphere, geosphere, atmosphere, hydro- and cryosphere and hence affecting crucial functioning of the whole Earth system...

This publication prepared by a team of experts in marine science was released to provide the industry and all interested people with a platform allowing for the presentation of both regional and global perspectives of the experiences on responses to global changes to address the key issues, for example the increasing need for water, supply variability, environmental flows and other related aspects.

The content of the book will help readers to build the required links between policy/science and practice in the field of management and governance of the water resources. The book also addresses the latest technological and institutional innovations and also identifies the keys in which the research activities could assist the practice and policy related to the sustainable freshwater management. The proper management of the fresh water is considered one of the most important challenges to reach the sustainability within the global environment.

More than a century ago, B. Helland-Nanses and I. Snadstrom and proposed a method of computing the ocean currents on the basis of the water density distribution. Later, this method became known as the dynamic method for computing elements of the ocean currents, or hydrological data analysis method.

This is the indirect method and fully bases on the theoretical assumption that the coriolis force and horizontal pressure gradient are in equilibrium in the steady state below the mixed layer of the ocean surface. The velocities of the current are calculated by means of the dynamic method. The present volume is the author's attempt to properly justify the method referred to above, theoretically and also to shed some light on the nature of currents calculated/computed using this method.

It also examines the importance of the depth of reference surface and the accuracy of the computations. In addition, the book contains the descriptions of the structure of the gradient component of a wind-driven current velocity.

However, the author of the title does not attempt to provide a thorough treatise on the method in question, but is rather trying to analyze some of the important aspects of the theoretical principles of the dynamic method together with the possible practical applications, using the ocean currents theory.

The nice and interesting publication offered here, was compiled by an excellent team made of truly recognized industry experts working in the field of marine science and has actually been dedicated to the submarine mass movements considered critically important part of the turbidity.

The opening section of the volume explains the basic nature of the submarine mass movements including the triggers and also mechanics, plus major geo-technical properties - among the issues that have been covered within present section there are advanced dynamic testing of the soil, self-organizing maps, submarine slope failure, mass wasting dynamics, micaceous sand, drag forces acting on the suspended pipelines and lines laid on the sea floor, subaqueous deposits, control of the slope destabilization, shear rupture propagation etc.

The second section is mainly focusing on the analysis of the several real-life case studies plus the assessment of hazards involved - it covers such topics as the mass-transport deposit, submarine mass transport, sediment redistribution and mass wasting in particular geographic areas, risk analysis conducted for the submarine mudslides induced by hurricane-wave effect, gas-generated pore pressure, slope instability, morphodynamic instability and numerous specific topics that would otherwise be very difficult to find in any other publication.​

Nowadays, marine debris that are discharges from the vessels and other source, including the trash as well as the lost fishing gear, is seriously contributing to the ongoing spoiling of the beaches and fouling of the seafloor and surface waters; in addition to that, it causes significant harm to the marine mammals and other negative effects.

Regretfully, the existing domestic laws and international conventions that are intended to provide the due control of the discharge of marine debris, have not been too successful, and one of the reasons for that was that the laws provided little incentive to the changes in the behavior.

The authors of the present publication have made an attempt to properly identify the established ways of reduction of the wastes, decrease in the disposal of waste at marine ports, and also to strengthen the whole regulatory framework towards a zero-discharge in the environment of the sea. The progress in this field will mainly depend on a commitment to the sustained funding and also on the appropriate support.

The relevant authorities should target research in order to get to the sound understanding of the sources, associated fates and potential impacts of marine debris by means of the planning and prioritization of the related activities, and also provide the required support to the establishment of the rigorous protocols allowing to monitor at a broad variety of scales.

According to the author, his original  intention was that this volume would serve several different purposes, including giving readers an overall picture of the several aspects of charting and surveying and, at the same time, going a bit deeper into those of the subjects which commonly seem to require some additional attention, or are in need of a more modern approach.

Also, where deemed desirable, several completely new subjects have been introduced. In the meantime, it was considered a necessity not to overlook simpler methods and less complicated equipment, as not every survey ship possesses the modern equipment for the electronic data processing on board with all required instruments recording on-line. When writing this volume, the author hoped that it would assist hydrographic as well as all other marine surveyors facing with the difficulties when establishing an efficient hydrographic office and performing effective surveys for their country; who are often required to provide guidance to younger officers, not having readily available sophisticated data collection and further processing devices.

As declared by W. Langeraar, the author, a serious need exists for a title not only discussing the latest equipment and all associated methodologies, but which is also covering less complicated instruments and methods...
