Marine Chemistry

This book, first of its kind in India is a modest attempt of the author to bridge the gap of a text book on Marine Chemistry for undergraduate (Honours) and post-graduate students of Marine/Ocean Sciences, Earth/Environmental, and Fishery Sciences of the Indian Universities. It is designed in such a way that it can be read on its own or studied as part of any of the above courses. The subject is introduced at a level which can be followed easily by practicing Environmental Scientists and Engineers. The book is intended to provide latest information on chemical processes and distribution of chemical constituents in world oceans with special emphasis on the Indian seas. A multidisciplinary approach is followed in presenting the subject. The book not only deals with the basic principles of chemistry, but also with physico-chemical and biogeochemical processes in the oceans such as transfer of gases across air-sea interface, biogeochemical cycling of nutrients and trace metals, and their involvement in food chain and life processes. Developments on the use of radioactive isotopes as tracers for the study of oceanic processes, geochronology of sediments and growth rates of manganese nodules are presented in a lucid manner. Chemical reactions and mechanism of photosynthesis, interrelationships of organic matter and nutrients with primary production are explained in detail.
