This landmark publication takes the 50th anniversary of the publication of the seminal paper by the Danish scientist, Einer Steemann Nielsen, as an occasion to assess the development, present state and future of the major aspects in freshwater and marine plankton productivity. Each chapter of this important work has been written by internationally-acknowledged experts in the subject, and the whole has been carefully drawn together and edited to provide a book that is an essential tool and reference for all aquatic scientists.The book takes ascending temporal and spatial size scale as its framework - covering molecular to geological scales. Chapters include reviews of physiology and biochemistry, measurement of phytoplankton productivity, the supply and uptake of nutrients, variability in processes and production, the evolution of the carbon cycle, and ecosystems. The subject is set in context with a chapter covering the work of Steemann Nielsen, whose work inspired the last 50 years of aquatic productivity studies. Historical aspects are discussed together with thought-provoking assessments of modern technological approaches and where future research emphasis should be focussed.Phytoplankton Productivity provides, in one book, cutting edge reviews and key facts on the subject, making it a vital information source for marine and freshwater biologists, oceanographers, ecologists, environmental scientists and plant scientists. Copies should also be available in libraries of any research establishment and university as a reference for students, wherever these subjects are studied and taught.Also available from Blackwell PublishingAquatic PhotosynthesisP.

Sea ice, which covers up to 7% of the planet’s surface, is a major component of the world’s oceans, partly driving ocean circulation and global climate patterns. It provides a habitat for a rich diversity of marine organisms, and is an extremely valuable source of information in studies of global climate change and the evolution of present day life forms. Increasingly sea ice is being used as a proxy for extraterrestrial ice covered systems. Sea Ice provides a comprehensive review of our current available knowledge of polar pack ice, the study of which is severely constrained by the logistic difficulties of working in such harsh and remote regions of the earth. The book’s editors, Drs Thomas and Dieckmann have drawn together an impressive group of international contributing authors, providing a well-edited and integrated volume, which will stand for many years as the standard work on the subject. Contents of the book include details of the growth, microstructure and properties of sea ice, large-scale variations in thickness and characteristics, its primary production, micro-and macrobiology, sea ice as a habitat for birds and mammals, sea ice biogeochemistry, particulate flux, and the distribution and significance of palaeo sea ice. Sea Ice is an essential purchase for oceanographers and marine scientists, environmental scientists, biologists, geochemists and geologists. All those involved in the study of global climate change will find this book to contain a wealth of important information. All libraries in universities and research establishments where these subjects are studied and taught will need multiple copies on their shelves.

The growth of interest in community work during the seventies was very marked. But while much had been written on the actual practice of community work, there was for too long a lack of British material on the vital subjects of useful theory, training and the development of skills. In this title, originally published in 1977, the authors brought together for the National Institute for Social Work experienced teachers and practitioners of community work in an integrated and carefully structured textbook which would further understanding of the means through which community workers develop their knowledge and skills; it would be widely welcomed by all those involved in aspects of community work – as teachers, students, practitioners, supervisors and as local authority training officers. The first part of the book has four chapters on the principle means through which community workers develop their skills within their employing agencies. Part two deals with theories and the contribution made to community work by the social sciences, group work, research methods and management and planning studies. The last part of the book contains three papers which examine the major problems and issues in the placement, learning experiences and assessment of students on field work.

Since the late 1960s, community work had emerged in its own right as an occupation with an increasingly important contribution to make both to ways of thinking within the field of social policy, and to day-to-day social work practice and the resolution of pressing community issues. Its practitioners had grown in numbers and experience, while community work ideas and methods continued to influence developments in a variety of other ‘neighbouring’ occupations. Originally published in 1980, the editors of this NISW collection suggest that if community workers are to remain effective, then they must stay on the boundaries of the agencies that employ them and of the groups with whom they work. This theme of the ‘boundary nature’ of community work is examined in detail in the Introduction and is subsequently taken up by the other contributors to the book.This title is organised under three main headings – a survey section on the history, philosophy and theories of community work in the United Kingdom; a series of case studies that suggest the diversity of the interests of community work; and an analysis of the growth of community work as an occupation and the spread of its influence through related professions and disciplines. This mix of theory, practice and analysis made the book of special importance both to practising community workers and to community work teachers and students at the time. In addition, the book would have been of direct interest to community oriented administrators, professionals, teachers and students in other human service fields such as health, education, housing, planning and the personal social services, as well as to elected members and administrators in central and local government more generally. It will now be welcomed by anyone who seeks a critical account of the historical activities of community work, written by experienced practitioners and teachers.

Originally published in 1976, the aim of this book was to understand the contribution of community work to meeting some of the problems to be found in many of Britain’s inner city neighbourhoods. It describes the community work process and the tasks, roles and skills of the professional community worker as he interacts with neighbourhood groups and service agencies. The author also indicates some of the strengths of collective action and its likely benefits and costs to those who participate. The book includes an examination of how to effect changes in the delivery of services from statutory and voluntary agencies, as well as an assessment of the community project of which the author was a staff member. The book is a contribution to the theory of community work and practice, and it is based upon the experience of those who worked in, and used, the Southwark Community Project, established by the National Institute for Social Work. It was written for practitioners, teachers and students of community work, as well as for other closely involved in community affairs such as teachers, playground workers, planners and social workers.

Originally published in 1983, The Making of Community Work is the outcome of a two-year study of community work in the United Kingdom. The main purpose of the study was to review the development of community work, and to suggest some of the issues in practice and training that might be important in the 1980s. Much of the first part of the book is taken up with the emergence of community work as an occupation; David Thomas tries to clarify its contribution to a number of political and social processes, and to define community work in a way which distinguishes it from other kinds of interventions. The second part of the book deals with training, research, literature and employment in community work; it includes a review of college and field-based training opportunities, and a critical discussion of the state of theory and ideology in the occupation.It was hoped it would be an important source of ideas and inspiration for the years ahead. It was the first major review of community work since its re-discovery in the 1960s; it will still be of interest to all those involved in community work, or wishing to understand its influence on other professions. The book was intended for fieldworkers, administrators, policy-makers, trainers and students in community work and in related occupations and disciplines. Thomas presents his ideas clearly, and his ability to look critically at some of the basic assumptions in community work makes for stimulating and enjoyable reading.

Originally published in 1986, White Bolts, Black Locks was a major contribution to the national debate about racism, racial justice and the relationships between the white and black British. It examines the participation of black people in community activities, and the effects on that participation of personal and institutional forms of racism. This thought-provoking and readable book has much to say to white and black professionals who work together, for the author describes the way in which ‘white speak’ and ‘black speak’ are used to build self-protective stockades.David Thomas explores the idea of community capability, and how black and white neighbours try to live together and improve their livelihood. He presents stimulating material about neighbourhoods, and suggests why they must be given more recognition as a proper part of the social structure.The book will still be of historical interest to practitioners, volunteers and local residents working in urban neighbourhoods, and to students in social work, community development, politics, sociology and social policy and administration. It is a book that should not be ignored by anyone with an interest in the significance of neighbourhood processes and development.

Over the past 20 years the study of the frozen Arctic and Southern Oceans and sub-arctic seas has progressed at a remarkable pace. This third edition of Sea Ice gives insight into the very latest understanding of the how sea ice is formed, how we measure (and model) its extent, the biology that lives within and associated with sea ice and the effect of climate change on its distribution. How sea ice influences the oceanography of underlying waters and the influences that sea ice has on humans living in Arctic regions are also discussed.  Featuring twelve new chapters, this edition follows two previous editions (2001 and 2010), and the need for this latest update exhibits just how rapidly the science of sea ice is developing. The 27 chapters are written by a team of more than 50 of the worlds’ leading experts in their fields. These combine to make the book the most comprehensive introduction to the physics, chemistry, biology and geology of sea ice that there is.This third edition of Sea Ice will be a key resource for all policy makers, researchers and students who work with the frozen oceans and seas.

Arctic EcologyThe Arctic is often portrayed as being isolated, but the reality is that the connectivity with the rest of the planet is huge, be it through weather patterns, global ocean circulation, and large-scale migration patterns to name but a few. There is a huge amount of public interest in the 'changing Arctic,' especially in terms of the rapid changes taking place in ecosystems and exploitation of resources. There can be no doubt that the Arctic is at the forefront of the international environmental science agenda, both from a scientific aspect, and also from a policy/environmental management perspective.This book aims to stimulate a wide audience to think about the Arctic by highlighting the remarkable breadth of what it means to study its ecology. Arctic Ecology seeks to systematically introduce the diverse array of ecologies within the Arctic region. As the Arctic rapidly changes, understanding the fundamental ecology underpinning the Arctic is paramount to understanding the consequences of what such change will inevitably bring about.Arctic Ecology is designed to provide graduate students of environmental science, ecology and climate change with a source where Arctic ecology is addressed specifically, with issues due to climate change clearly discussed. It will also be of use to policy-makers, researchers and international agencies who are focusing on ecological issues and effects of global climate change in the Arctic.

New edition of the leading resource on the Arctic and Southern Oceans with contributions from the world’s experts on sea ice Sea Ice delivers insights into the very latest understanding of sea ice dynamics, how we measure (and model) its extent, the ecosystems that depend on sea ice, and the effect of climate change on its distribution. The book also discusses how sea ice influences the oceanography of underlying waters and the influence that sea ice has on the world’s climate. This newly revised and updated Fourth Edition looks at ice-based food webs and the impact on global geopolitics as well as changes in human activity in the Arctic. Written by a team of more than 80 of the world’s leading experts from 13 countries, Sea Ice includes information on: Sea ice thickness distribution and snow and surface processes on sea iceThe short-term and long-term dynamics of Arctic versus Antarctic Sea iceCurrent methods of satellite remote sensing of sea iceThe ecology of sea ice, from microbes to mammals to marine birdsThe cycling of contaminants across the ocean-sea ice-atmosphere interfaceIn its new edition, Sea Ice remains the leading multidisciplinary resource on the subject for all policy makers, researchers, and students with an interest in the polar regions and their role in the world’s oceanic systems.

Two thirds of our planet is covered by oceans and seas. Over recent decades developments in ocean science have dramatically improved our understanding of the key role oceans play in the Earth System, and how vital they are for regulating global climate. Humans depend on the oceans for many resources, but at the same time their impacts on the marine systems around the world are of increasing concern. Introducing Oceanography has been written by two leading oceanographers to provide a succinct overview of the science of the study of the seas for students and for the interested adult wanting a topical guide to this enormous and complex subject. The initial chapters describe the oceans and the forces at work within them. The authors then discuss the effects of light, the chemistry of the seas and the food web before surveying biological oceanography in the main oceanic regions. The final chapter looks at the methodology of ocean study. Copiously illustrated, this book is intended for those whose interest in oceanography has been stimulated, perhaps by media coverage of declining resources or climate change and who want to know more. Technical terms are kept to a minimum and are explained in a glossary.
