This book introduces the variety of research skills necessary for integrated environmental science, which are applicable to atmospheric, oceanic, terrestrial, and biota studies. The surface environment of the earth is a complex system consisting of atmospheric, oceanic, and terrestrial regions as well as the biota therein, all of which interact with one another to various extents. The integration of research disciplines including earth science, biology, chemistry, physics, and social science is a core of environmental science. It encourages students and early-career scientists to take a broad view of the whole environmental system. Detailed practical information for the field or laboratory work in this book helps students and scientists to plan research strategy for their own scope and interests. In addition, this book is also useful for professionals to teach field and laboratory work in environmental science to students. This book is based on the environmental summer school program organized by the Institute of Nature and Environmental Technology, Kanazawa University, in Japan.
