"Marine photosynthesis provides for at least half of the primary production worldwide..." Photosynthesis in the Marine Environment constitutes a comprehensive explanation of photosynthetic processes as related to the special environment in which marine plants live. The first part of the book introduces the different photosynthesising organisms of the various marine habitats: the phytoplankton (both cyanobacteria and eukaryotes) in open waters, and macroalgae, marine angiosperms and photosymbiont-containing invertebrates in those benthic environments where there is enough light for photosynthesis to support growth, and describes how these organisms evolved. The special properties of seawater for sustaining primary production are then considered, and the two main differences between terrestrial and marine environments in supporting photosynthesis and plant growth are examined, namely irradiance and inorganic carbon. The second part of the book outlines the general mechanisms of photosynthesis, and then points towards the differences in light-capturing and carbon acquisition between terrestrial and marine plants. This is followed by discussing the need for a CO2 concentrating mechanism in most of the latter, and a description of how such mechanisms function in different marine plants. Part three deals with the various ways in which photosynthesis can be measured for marine plants, with an emphasis on novel in situ measurements, including discussions of the extent to which such measurements can serve as a proxy for plant growth and productivity. The final chapters of the book are devoted to ecological aspects of marine plant photosynthesis and growth, including predictions for the future.

Without light there would be no life in the sea. Since the seas were the cradle for the evolution of all life forms, the theme of this book is central to our understanding of the interaction between living organisms and their environments. To express the breadth of research in this area, leading experts in topics as diverse as satellite imagery and molecular biology have contributed to this collection of essays on light and life in the sea, first published in 1990. Intended for all with an interest in the marine environment, this book aims to present the reader with a sampler of the exciting research that is underway and to provide an introduction to its broad compass.

This summarises the latest advances in the physiological and ecological responses of marine species to a wide range of potential stressors resulting from current anthropogenic activity, and provides a perspective on future outcomes for some of the most pressing environmental issues facing society today.

The oceans cover more than 70% of the earth's surface to an average depth of almost 4000 metres. It is therefore not surprising that exchanges that occur between ocean and atmosphere exert major influences on the global climate. In addition, there is great variety within the expanses of the ocean, including large temperature differences, and enormous biodiversity brought about by the great chemical diversity within the marine environment. Written by international experts in the field, Chemistry in the Marine Environment offers a multidisciplinary and authoritative review of this important topic. Included is a review of the opportunities and challenges in developing new pharmaceuticals from the sea and an examination of contamination and pollution in the marine environment, which is a cause of great concern world-wide. The international perspective of this book will engage the interest and attention of a wide readership, from chemical oceanographers to policymakers, from students in environmental science to those in oceanography programmes.

Since the first edition of Nitrogen in the Environment published in 1983, it has been recognized as the standard in the field. In the time since the book first appeared, there has been tremendous growth in the field with unprecedented discoveries over the past decade that have fundamentally changed the view of the marine nitrogen cycle. As a result, this Second Edition contains twice the amount of information as contained in the first edition. This updated edition is now available online, offering searchability and instant, multi-user access to this important information. *The classic text, fully updated to reflect the rapid pace of discovery*Provides researchers and students in oceanography, chemistry, and marine ecology an understanding of the marine nitrogen cycle*Available online with easy access and search - the information you need, when you need it

This book provides an introduction to recent analytical and experimental studies of plant growth in the sea. The physiology and ecology of marine plants are, therefore, emphasized.
