Sean Conway was stuck in a life dead end of his own making when he heard about a round the world cycling race. He was immediately inspired – but it was a huge undertaking and he’d hardly been on a bike in years. Could he really cycle all the way round the world, solo and unsupported? Six months later, after completing a punishing training schedule and packing up everything he owned into boxes, Sean was in Greenwich Park on the start line of the adventure of a lifetime. Soon he was way ahead of schedule, averaging 180 miles per day, and on course to break the round the world cycling record. But then disaster struck, and Sean was forced to confront the possibility that he may not be able to complete the race... In the course of his 16,000-mile journey, Sean travelled the famous pan-American highway across the Atacama Desert, outran tornados, relied on fellow travellers to ferry water across the Australian outback, and inadvertently joined a cycle club in Mumbai. He learnt things about himself he didn’t know and rediscovered a spirit of adventure that changed everything. This is a book about an amazing and sometimes incredibly difficult journey, but it’s also a book about never giving up when there’s an opportunity to follow your dreams.

Nonliving organic matter (NLOM) comprises the bulk of the organic carbon stored in the terrestrial biosphere and a major part of the organic carbon in the sea. Organic substances, which include litter, marine detritus, dissolved organic matter, and soil organic matter, have diverse effects on the Earth’s biogeochemical processes and serve as a major reservoir of biospheric carbon, which can be transformed to carbon dioxide, methane, and other "greenhouse" gases. Given this broad spectrum of effects, efforts to adapt to or perhaps benefit from global change require a better understanding and an ability to predict the role of NLOM in the global environment. The overall objective of this volume is to provide experimental and modeling strategies for the assessment of the sensitivity of the global carbon cycle to changes in nonliving organic pools in terrestrial and aquatic ecosystems. The discussions in this volume consider how best to characterize and quantify pools and fluxes of NLOM, the role of NLOM cycling on a global scale, human and climatic perturbations of interactions between NLOM and nutrients, and biological, chemical, and physical processes that control the production and degradation of NLOM, with an emphasis on processes that affect the persistence of NLOM in the environment. One of the most unique aspects of this volume is that it represents extensive exchanges between leading international scientists from both aquatic and terrestrial backgrounds. It will be of particular interest to organic geochemists, microbiologists, ecologists, soil scientists, agricultural scientists, marine chemists, limnologists, and modelers. Goal of this Dahlem Workshop: to devise experimental and modeling strategies for assessment of the sensitivity of the global carbon cycle to changes in nonliving organic pools.

A new section of short reviews called 'Frontiers' was introduced within the Elsevier journal Earth and Planetary Science Letters (EPSL) in 2002 under the Editorship of Alex Halliday from ETH Zurich, Switzerland. These high profile Frontiers articles are written by leading experts and published as the opening pages to regular issues of EPSL. The reason for this development is that the Editors of EPSL believe there is an important niche to be filled with fast communications that bring the scientific community up-to-speed on interesting new areas of science. Frontiers articles are therefore specifically intended for the non-specialist earth and planetary science readership. In order to reach a broader readership, those without subscriptions to the journal, Frontiers articles will now also be published in a new book series, the EPSL Frontiers series. Volume 1 will contain all 2002 and 2003 Frontiers articles. Future volumes will contain one year of articles each.

Introduction to Geomicrobiology is a timely and comprehensive overview of how microbial life has affected Earth’s environment through time. It shows how the ubiquity of microorganisms, their high chemical reactivity, and their metabolic diversity make them a significant factor controlling the chemical composition of our planet. The following topics are covered: how microorganisms are classified, the physical constraints governing their growth, molecular approaches to studying microbial diversity, and life in extreme environments bioenergetics, microbial metabolic capabilities, and major biogeochemical pathways chemical reactivity of the cell surface, metal sorption, and the microbial role in contaminant mobility and bioremediation/biorecovery microbiological mineral formation and fossilization the function of microorganisms in mineral dissolution and oxidation, and the industrial and environmental ramifications of these processes elemental cycling in biofilms, formation of microbialites, and sediment diagenesis the events that led to the emergence of life, evolution of metabolic processes, and the diversification of the biosphere.

Providing a guide for marine conservation practice, Marine Conservation takes a whole-systems approach, covering major advances in marine ecosystem understanding. Its premise is that conservation must be informed by the natural histories of organisms together with the hierarchy of scale-related linkages and ecosystem processes. The authors introduce a broad range of overlapping issues and the conservation mechanisms that have been devised to achieve marine conservation goals. The book provides students and conservation practitioners with a framework for thoughtful, critical thinking in order to incite innovation in the 21st century. "Marine Conservation presents a scholarly but eminently readable case for the necessity of a systems approach to conserving the oceans, combining superb introductions to the science, law and policy frameworks with carefully chosen case studies. This superb volume is a must for anyone interested in marine conservation, from students and practitioners to lay readers and policy-makers." —Simon Levin, George M. Moffett Professor of Biology, Department of Ecology & Evolutionary Biology, Princeton University

Minerals existed long before any forms of life, playing a key role in the origin and evolution of life; an interaction with biological systems that we are only now beginning to understand. Exploring the traditional strand of mineralogy, which emphasises the important mineral families, the well-established analytical methods (optical microscopy and X-ray diffraction) and the dramatic developments made in techniques over recent decades, David Vaughan also introduces the modern strand of mineralogy, which explores the role minerals play in the plate tectonic cycle and how they interact with the living world. Demonstrating how minerals can be critical for human health and illness by providing essential nutrients and releasing poisons, Vaughan explores the multitude of ways in which minerals have aided our understanding of the world. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

For the past three decades, it has been possible to measure the earth's static gravity from satellites. Such measurements have been used to address many important scientific problems, including the earth's internal structure, and geologically slow processes like mantle convection. In principle, it is possible to resolve the time-varying component of the gravity field by improving the accuracy of satellite gravity measurements. These temporal variations are caused by dynamic processes that change the mass distribution in the earth, oceans, and atmosphere. Acquisition of improved time-varying gravity data would open a new class of important scientific problems to analysis, including crustal motions associated with earthquakes and changes in groundwater levels, ice dynamics, sea-level changes, and atmospheric and oceanic circulation patterns. This book evaluates the potential for using satellite technologies to measure the time-varying component of the gravity field and assess the utility of these data for addressing problems of interest to the earth sciences, natural hazards, and resource communities.
