This Volume belongs to a series on Oceanography. It is designed so that it can be read on its own, or used as a supplement in oceanogrphy courses. After a brief introduction to sea-floor sediments, the book shows how the activities of marine organisms cycle nutrients and other dissolved constituents within the oceans, and influence the rates at which both solid and dissolved material is removed to sediments. It goes on to review the carbonate system and shows how sediments that come from continental areas may be transported to the deep sea, explores what sea-floor sediments have taught us about the history of the oceans, and describes the biological and chemical processes that continue long ...
This is the fourth Volume of the six Volume Open University set. Each Volume is used by students as a relevant part of the Open University course in the UK, but designed so that it can equally be used as an individual text book. This Volume describes waves, their measurement and characteristics, their behaviour in shallow water and unusual waves. It also considers mainly theoretical aspects of sediment movement and deposition of currents, wave estuaries, and the interaction of waves, tides and river flow in deltas. Concludes with a look at shelf-sea processes and their mineral resources. Each Volume in this set is well laid out and copiously illustrated with full colour photographs, graphs and graphics. Questions to help develop arguments and/or understanding can be found in the text and at the end of each chapter, with worked answers provided at the back of each Volume. Each chapter also concludes with a summary to help consolidate understanding before the next chapter is begun.
This is an invaluable textbook, prepared by the Open University team and designed so that it can be read on its own or as part of the OU course. This second edition has been fully revised and updated including new colour illustrations increasing the striking spread of full colour diagrams throughout the book. The clarity of the text has been improved, providing comprehensive coverage of the evolution of ocean basins and their structure in a clear, concise manner aimed specifically at the student market.In this second edition the technological advances in fields as diverse as:- deep-towed instruments for `sniffing' hydrothermal plumes- mapping the sea-floor by sophisticated sonar techniques -...
This book introduces the inter-disciplinary study of childhood and youth and the multi-agency practice of professionals who serve the needs of children, young people and their families. Exploring key theories and central ideas, research methodology, policy and practice, it takes a holistic, contextual approach that values difference and diversity. It examines concepts such as identity, representation, creativity and discourse and issues such as ethnicity, gender and the ′childhood in crisis′ thesis. Furthermore, it challenges opinion by exploring complex and controversial modern-day issues, and by engaging with a range of perspectives to highlight debates within the field.
Investigating Psychology uses a small selection of classic studies to introduce students to a variety of research methods used by psychologists and to the different approaches to the study of mind and behaviour: the emphasis is on how psychologists carry out their investigations and why.
"Book 2 Time series covers methods for analysing data collected over time, and forecasting future values using exponential smoothing and ARIMA models." -- The Open University course webpage.
The first two chapters outline the causes of circulation patterns in the atmosphere and oceans, emphasizing the interactions between them. Chapter 3 deals with the surface circulation (including mesoscale eddies), using a minimum of mathematics. Chapter 4 reviews the history of ideas about ocean circulation (with special reference to the North Atlantic gyre), and Chapter 5 describes the major current systems at high and low latitudes. The final Chapter returns to the theme of ocean-atmosphere interaction, especially the global transport of heat and freshwater, and the formation of sub-surface water masses.Fully illustrated in four coloursFully illustrated in four colours
Seawater: Its Composition, Properties and Behaviour provides a comprehensive introduction to marine science. This book is divided into seven chapters. Chapter 1 summarizes the special properties of water and the role of the oceans in the hydrological cycle. The distribution of temperature and salinity in the oceans and their combined influence on density, stability, and vertical water movements are discussed in Chapters 2 to 4. The fifth chapter describes the behavior of light and sound in seawater and provides examples of the application of acoustics to oceanography. Chapter 6 examines the composition and behavior of the dissolved constituents of seawater, covering minor and trace constituents and major ions, as well as dissolved gases and biologically important nutrients. Residence times, speciation, and carbonate equilibria are also deliberated. The last chapter provides a short review of ideas about the history of seawater, involvement of the oceans in global cycles, and their relationship to climatic change. This publication is beneficial to oceanographers and marine biologists, including students that are interested in marine science.

There is an enormous variation in how cardiovascular diseases affect people's lives. This is reflected in this book, which uses case studies to describe how cardiovascular diseases can affect individuals.Chapters 1 and 2 are concerned with introducing cardiovascular dieases and normal physiology of the heart and circulation. Chapters 3 and 4 look at cardiovascular diseases in the context of the risk factors, social distribution and methods of preventing these dieases. Chapter 5 looks more closely at the disease process at the vascular level whilst chapters 6 and 7 look at the different conditions that can lead to heart failure, and introduces the different diagnostic tests which can help to differentiate each condition. The remaining chapters of the book are concerned with the various ways in which cardiovascular disease may be treated, including medical management and the surgical treatments for angina, breathlessness and heart attacks.This book also considers what it means to live with cardiovascular disease, and examines lifestyle changes, practical considerations and the psychological implications of having heart disease.
