Earth's Early Atmosphere and Oceans, and The Origin of Life


Book Description

This book provides a comprehensive treatment of the chemical nature of the Earth’s early surface environment and how that led to the origin of life. This includes a detailed discussion of the likely process by which life emerged using as much quantitative information as possible. The emergence of life and the prior surface conditions of the Earth have implications for the evolution of Earth’s surface environment over the following 2-2.5 billion years. The last part of the book discusses how these changes took place and the evidence from the geologic record that supports this particular version of early and evolving conditions.




Ocean-Atmosphere Interactions of Gases and Particles


Book Description

The oceans and atmosphere interact through various processes, including the transfer of momentum, heat, gases and particles. In this book leading international experts come together to provide a state-of-the-art account of these exchanges and their role in the Earth-system, with particular focus on gases and particles. Chapters in the book cover: i) the ocean-atmosphere exchange of short-lived trace gases; ii) mechanisms and models of interfacial exchange (including transfer velocity parameterisations); iii) ocean-atmosphere exchange of the greenhouse gases carbon dioxide, methane and nitrous oxide; iv) ocean atmosphere exchange of particles and v) current and future data collection and synthesis efforts. The scope of the book extends to the biogeochemical responses to emitted / deposited material and interactions and feedbacks in the wider Earth-system context. This work constitutes a highly detailed synthesis and reference; of interest to higher-level university students (Masters, PhD) and researchers in ocean-atmosphere interactions and related fields (Earth-system science, marine / atmospheric biogeochemistry / climate). Production of this book was supported and funded by the EU COST Action 735 and coordinated by the International SOLAS (Surface Ocean- Lower Atmosphere Study) project office.




Atmospheric Evolution on Inhabited and Lifeless Worlds


Book Description

A comprehensive and authoritative text on the formation and evolution of planetary atmospheres, for graduate-level students and researchers.




Atmosphere—Ocean Dynamics


Book Description

Atmosphere-Ocean Dynamics deals with a systematic and unified approach to the dynamics of the ocean and atmosphere. The book reviews the relationship of the ocean-atmosphere and how this system functions. The text explains this system through radiative equilibrium models; the book also considers the greenhouse effect, the effects of convection and of horizontal gradients, and the variability in radiative driving of the earth. Equations in the book show the properties of a material element, mass conservation, the balance of scalar quantity (such as salinity), and the mathematical behavior of the ocean and atmosphere. The book also addresses how the ocean-atmosphere system tends to adjust to equilibrium, both in the absence and presence of driving forces such as gravity. The text also explains the effect of the earth's rotation on the system, as well as the application of forced motions such as that produced by wind or temperature changes. The book explains tropical dynamics and the effects of variation of the Coriolis parameter with latitude. The text will be appreciated by meteorologists, environmentalists, students studying hydrology, and people working in general earth sciences.




The Chemistry of Life’s Origins


Book Description

This volume contains the lectures presented at the second course of the International School of Space Chemistry held in Erice (Sicily) from October 20 - 30 1991 at the "E. Majorana Centre for Scientific Culture". The course was attended by 58 participants from 13 countries. The Chemistry of Life's Origins is well recognized as one of the most critical subjects of modem chemistry. Much progress has been made since the amazingly perceptive contributions by Oparin some 70 years ago when he first outlined a possible series of steps starting from simple molecules to basic building blocks and ultimate assembly into simple organisms capable of replicating, catalysis and evolution to higher organisms. The pioneering experiments of Stanley Miller demonstrated already forty years ago how easy it could have been to form the amino acids which are critical to living organisms. However we have since learned and are still learning a great deal more about the primitive conditions on earth which has led us to a rethinking of where and how the condition for prebiotic chemical processes occurred. We have also learned a great deal more about the molecular basis for life. For instance, the existence of DNA was just discovered forty years ago.







Atmosphere, Ocean and Climate Dynamics


Book Description

For advanced undergraduate and beginning graduate students in atmospheric, oceanic, and climate science, Atmosphere, Ocean and Climate Dynamics is an introductory textbook on the circulations of the atmosphere and ocean and their interaction, with an emphasis on global scales. It will give students a good grasp of what the atmosphere and oceans look like on the large-scale and why they look that way. The role of the oceans in climate and paleoclimate is also discussed. The combination of observations, theory and accompanying illustrative laboratory experiments sets this text apart by making it accessible to students with no prior training in meteorology or oceanography.* Written at a mathematical level that is appealing for undergraduates andbeginning graduate students* Provides a useful educational tool through a combination of observations andlaboratory demonstrations which can be viewed over the web* Contains instructions on how to reproduce the simple but informativelaboratory experiments* Includes copious problems (with sample answers) to help students learn thematerial.




An Ocean of Air


Book Description

The science and history of what lies between us and space: “I never knew air could be so interesting.” —Bill Bryson, New York Times bestselling author of The Body: A Guide for Occupants A flamboyant Renaissance Italian discovers how heavy our air really is (the air filling Carnegie Hall, for example, weighs seventy thousand pounds). A one-eyed barnstorming pilot finds a set of winds that constantly blow five miles above our heads. An impoverished American farmer figures out why hurricanes move in a circle by carving equations with his pitchfork on a barn door. A well-meaning inventor nearly destroys the ozone layer (he also came up with the idea of putting lead in gasoline). A reclusive mathematical genius predicts, thirty years before he’s proven right, that the sky contains a layer of floating metal fed by the glowing tails of shooting stars. We don’t just live in the air; we live because of it. It’s the most miraculous substance on earth, responsible for our food, our weather, our water, and our ability to hear. In this exuberant book, science writer Gabrielle Walker peels back the layers of our atmosphere with the stories of the people who have uncovered its secrets. “A sense of wonder . . . animates Ms. Walker’s high-spirited narrative and speeds it along like a fresh-blowing westerly.” —The New York Times “A fabulous introduction to the world above our heads.” —Daily Mail on Sunday “A lively history of scientists’ and adventurers’ exploration of this important and complex contributor to life on Earth . . . readers will find this informative book to be a breath of fresh air.” —Publishers Weekly




The World is Blue


Book Description

"... [L]egendary marine scientist Sylvia Earle portrays a global ecosystem on the brink of irreversible environmental crisis unless we act immediately. A Silent Spring for our era, this eloquent, urgent, fascinating book reveals how the past 50 years of destructive--and ever accelerating--oceanic change threaten the very existence of life on Earth." -- back cover.
