'Seawater' has been substantially updated in this second edition to take account of recent developments in marine science. Sections dealing with difficult physical and chemical concepts have been developed on the basis of feedback from the first edition, making this an ideal learning tool for oceanography students.

Chapter 1 summarizes the special properties of water and the role of the oceans in the hydraulic cycle. The distribution of temperature and salinity in the oceans and how they influence water density and movements is then discussed. Light and sound in seawater are considered next, along with some uses of acoustics. These are followed by an examination of the composition and behaviour of dissolved constituents, including such topics as residence times, the control of pH, and redox relationships.
Finally, the history of seawater and its role in global cycles is reviewed, with special reference to climatic change and the CO2 problem.

The Great Ice Age documents and explains the natural climatic and palaeoecologic changes that have occurred during the past 2.6 million years, outlining the emergence and global impact of our species during this period. Exploring a wide range of records of climate change, the authors demonstrate the interconnectivity of the components of the Earths climate system, show how the evidence for such change is obtained, and explain some of the problems in collecting and dating proxy climate data.
One of the most dramatic aspects of humanity's rise is that it coincided with the beginnings of major environmental changes and a mass extinction that has the pace, and maybe magnitude, of those in the far-off past that stemmed from climate, geological and occasionally extraterrestrial events. This book reveals that anthropogenic effects on the world are not merely modern matters but date back perhaps a million years or more.

Many campus universities are now adopting and adapting distance education for some of their activities. Sir John Daniel discusses the changing role of distance education and training and how to gain a competitive advantage. The central question of the book is how the knowledge media can contribute to the renewal of universities, particularly through the further development of distance learning. Part of the book examines universities that have risen to the challenges of cost and accessibility by using technology in its widest sense.

The editors charged contributors to examine individual aspects of policy and practice considering, inter alia, three sub-themes. The first is the competence-based approach and its implementation; the second is an exploration of who are the winners and losers as government has placed national economic development at the heart of its policies and programmers for education and training. A third theme is the process of change and intervention itself. While apparent in all the chapters, it is most easily traced in the case studies where policies initiated at national level by government and other bodies are modified by factors in the local context and are implemented in ways which are acceptable to individual organizations. The New Training Initiative made competence-based qualifications a key component of its agenda for improving Britain's VET performance. This has now emerged as the pervasive influence on both VET policy and practice and, features with different degrees of optimism and unease in several chapters.

This book looks at how molecules react, and how the feasibility and outcome of chemical reactions can be predicted. Beginning with an introduction to the concept of an activity series of metals, Metals and Chemical Change then introduces chemical thermodynamics (enthalpy, entropy and free energy) and applies the concept to both inorganic and organic elements. A Case Study on batteries and fuel cells is also included. The accompanying CD-ROM includes video sequences of the reactions of metals with water, acid and aqueous ions, and gives the reader an opportunity to make experimental observations and predictions about chemical behaviour. A comprehensive Data Book of chemical and physical constants is included, along with a set of interactive self-assessment questions. The Molecular World series provides an integrated introduction to all branches of chemistry for both students wishing to specialise and those wishing to gain a broad understanding of chemistry and its relevance to the everyday world and to other areas of science. The books, with their Case Studies and accompanying multi-media interactive CD-ROMs, will also provide valuable resource material for teachers and lecturers.

This undergraduate teaching text and accompanying Periodic Table DVD, provides an introduction to the transition metals. The first two chapters introduce the reader to the chemistry of the first-row transition elements in different oxidation states, in particular +2 and +3 and their relative stability, largely using interactive activities and video on the DVD. This is followed by a study of coordination chemistry and the stability of complexes. Later chapters look at theories of metal-ligand bonding, in particular the way models can be used to rationalise many of the properties of transition metals and their compounds, such as colour, magnetism and stereochemistry. Starting with the simple, yet powerful crystal field approach, the book finishes with a largely pictorial treatment of molecular orbital theory. The text also includes interactive activities on the accompanying Periodic Table DVD, in-text questions with answers, full colour diagrams and revision exercises on an associated website www.rsc.org/metalsandlife

This book pursues possible strategies for synthesising mainly organic compounds, particularly those of interest to the health sector and related industries. Topics covered include addition reactions of aldehydes and ketones; the use of organometallic reagents to form carbon-carbon bonds (eg Grignard reagents); and radical reactions, including selectivity and chain reactions. Retrosynthetic analysis is introduced as a strategy for developing syntheses, along with biochemical pathways. Mechanism and Synthesis concludes with a Case Study on polymers, which demonstrates how chain reactions can be used to build up useful materials with specific properties, such as contact lenses.

Chemical Kinetics and Mechanism considers the role of rate of reaction. It begins by introducing chemical kinetics and the analysis of reaction mechanism, from basic well-established concepts to leading edge research. Organic reaction mechanisms are then discussed, encompassing curly arrows, nucleophilic substitution and E1 and E2 elimination reactions. The book concludes with a Case Study on Zeolites, which examines their structure and internal dimensions in relation to their behaviour as molecular sieves and catalysts. The accompanying CD-ROM contains the ""Kinetics Toolkit,"" a graph-plotting application designed for manipulation and analysis of kinetic data, which is built into many of the examples, questions and exercises in the text. There are also interactive activities illustrating reaction mechanisms.

The three-dimensional aspects of molecular shape can be crucial to both properties and reactions. The Third Dimension explores the arrangements of atoms in molecules and in different types of solids. Initial chapters describe the common crystal structures and how they are related to close-packed arrangements of ions. Metallic, ionic, molecular and extended covalent crystals are covered; major types of crystal defects are also discussed. The book then introduces isomerism, and explores the stereochemical consequences of the tetrahedral carbon atom. Chirality is also investigated. The book concludes with a Case Study on Liquid Crystals, which describes structures, properties and applications. As visualisation in 3D is an important part of this book, the accompanying CD-ROMs provide video material, interactive questions and exercises using models to aid understanding of crystals, organic molecules and stereochemistry. All necessary programs are provided.

Why do molecules adopt particular shapes? What determines the physical and chemical properties of a material? Molecular Modelling and Bonding answers these questions by introducing the ideas behind molecular and quantum mechanics, using a largely non-mathematical approach. Atomic and molecular orbitals, computational chemistry and bonding in solids are also discussed. A Case Study, Molecular Modelling in Drug Design, explores ways in which computer modelling, in conjunction with experimental techniques, is used to design new drugs. The accompanying CD-ROM illustrates applications of molecular and quantum mechanics, and includes many of the structures and orbitals illustrated in the text. It provides the programs necessary to view orbitals and 3D structures.

Alkenes and Aromatics examines the reaction mechanisms associated with carbon-carbon double bonds, and then goes on to look at aromatic substitution (nitration, halogenation, sulfonation and Friedel Crafts reactions). The formation and reactions of diazonium ions are also discussed. This knowledge is then applied to the synthesis of pseudoephedrine, highlighting the key aspects of synthesis, such as yields, stereochemistry and reaction conditions. A Case Study on the organic chemical industry completes the book, providing a background as to why understanding organic reactions is so important.
