Over the past decade, there has been a rapid increase in industrialization and human population growth along marine and coastal area of the world. This increase does much to further the well-being of the people and it also leaves severe impacts on coastal and marine environment. Approaching environmental science from a marine and coastal water perspective requires comprehensive background in the issues of geology, chemistry, biology, and in many cases atmospheric science to prevent and minimize adverse impacts of different types of pollution. This book is focused on environmental issues which include assessment of environmental impact and analysis of the different types of pollution and their effects on the coastal and marine environment. Moreover, it is provided for students and scientists in marine environment and/or ecosystem ecology, and some basic knowledge of marine biological research. Because of the diversity of illustrations and tabular information used in the examples of marine and coastal water studies, as well as the comprehensive bibliographic sources. I hope that, this book to be interesting and useful for reader, and I welcome your comments and feedback.
