The Galápagos Islands are renown for their unique flora and fauna, inspiring Charles Darwin in the elaboration of his theory of evolution. Yet in his Voyage of the Beagle, published in 1839, Darwin also remarked on the fascinating geology and volcanic origin of these enchanted Islands. Since then, the Galápagos continue to provide scientists with inspiration and invaluable information about ocean island formation and evolution, mantle plumes, and the deep Earth. Motivated by an interdisciplinary Chapman Conference held in the Islands, this AGU volume provides cross-disciplinary collection of recent research into the origin and nature of ocean islands, from their deepest roots in Earth's mantle, to volcanism, surface processes, and the interface between geology and biodiversity. Volume highlights include: Case studies in biogeographical, hydrological, and chronological perspective Understanding the connection between geological processes and biodiversity Synthesis of decades of interdisciplinary research in physical processes from surface to deep interior of the earth In-depth discussion of the concept of the island acting as a natural laboratory for earth scientists Integrated understanding of the Galápagos region from a geological perspective Collectively, The Galápagos presents case studies illustrating the Galápagos Archipelago as a dynamic natural laboratory for the earth sciences. This book would be of special interest to a multidisciplinary audience in earth sciences, including petrologists, volcanologists, geochronologists, geochemists, and geobiologists.

In this book, Guillermo Paz-y-Miño-C and Avelina Espinosa synthesize the events connecting the accidental discovery of the Galápagos Islands by Tomás de Berlanga in 1535 with Charles Darwin's exploration of the archipelago in 1835, Herman Melville's sketches of The Encantadas, or Enchanted Isles, of 1856, and the geopolitics to control Baltra Island, or "The Rock", where the United States established a military base from 1942 to 1946, during World War II. These themes are intertwined with discussions about the historical cartography of the Galápagos Islands, the geology of the archipelago, the hypotheses about the origins of the Galápagos terrestrial and marine organisms, and comparisons between Galápagos and other archipelagos, particularly Hawai'i. Offering over 250 figures and diagrams, this work will appeal to a broad audience, including professors in academia, college instructors, study-abroad and international field-trip leaders (with destination Galápagos), science writers, and policymakers.

Download In the Footsteps of Darwin Geoheritage Geotourism and Conservation in the Galapagos Islands Book in PDF, Epub and Kindle
This book provides the first-ever overview of and guide to the geological setting and related features of the famous, volcanically active Galapagos Islands, as well as an in-depth analysis of the setting’s relationship to the region’s unique and iconic ecology, and its conservation. Further, it provides an introduction to human settlement and activity on the islands, including the transition from subsistence to a fishing economy and more recently tourism, all in the context of increasingly restrictive conservation regulations. Importantly, the book also explores the development of the concept and practice of sustainable development across the islands as a framework for future economic development, pursuing an approach that reconciles the needs of the resident population with conservation of this fragile environment. The book is intended for a broad readership, from those engaged in geological and ecological studies, college and university educators and conservation practitioners, to more general visitors to the islands.

Ocean island volcanoes constitute some of the most prominent and rapidly-formed features on Earth, and yet they cannot be explained by conventional plate tectonics. Although typically associated with intraplate settings (hotspots), these volcanoes also occur in different geodynamic settings (near mid-ocean ridges). The nature of ocean island magmatism is still the subject of intense debate within the geological community. Traditionally it has been linked to the presence of mantle plumes at depth (e.g. Hawaii), although the interaction with plate tectonics is also recognized to play a significant role (e.g. Azores, Galápagos). Magma compositions may range from basaltic to more differentiated, which consequently is accompanied by striking changes in the eruption style from effusive-dominated to highly explosive volcanism. Understanding how these magmas evolve and how volcanic processes act at ocean island volcanoes are key issues of modern volcanology. Moreover, the growth of ocean island volcanoes from their rise on the seafloor as seamounts, to island emergence and subsequent formation of shield volcanoes (and in some cases large caldera volcanoes) is governed by multiple interrelated changes. It is well known that competing processes model ocean island volcanoes during alternating and/or coeval periods of construction and destruction. The geological evolution of these volcanoes results from the balance among volcanism, intrusions, tectonics, subsidence/uplift, mass wasting, sedimentation, and subaerial and wave erosion. A better knowledge of the interplay between these processes is crucial to obtain a more comprehensive understanding of the evolution of such volcanoes, and to the eventual formulation of a unified model for ocean island evolution. Ocean islands are especially vulnerable to volcanic eruptions and other geological hazards on account of their typical small size, rough topography and isolation, which make risk management and evacuation difficult. Volcanic eruptions, in particular, may have a significant impact on local populations, infrastructures, economy and even on the global climate. It is therefore fundamental to monitor these volcanoes with complementary geophysical, geodetic and geochemical techniques in order to forecast future eruptions and their impacts. However, the assessment of volcanic hazards on ocean islands is challenging due to the large variety of phenomena involved (e.g. lava flows, tephra fallout, pyroclastic density currents, lahars, gas emissions). Different approaches are used to assess volcanic hazards, either based on empirical methods or sophisticated numerical models, focusing on a single phenomenon or the combination of different hazards. This Frontiers Research Topic aims to promote discussion within the scientific community, representing an important step forward in our knowledge of ocean island volcanoes in order to serve as a reference for future research.

Galapagos Giant Tortoises brings together researchers and conservationists to share the most up-to-date knowledge of Galapagos giant tortoises. Despite being icons of the world-famous Galapagos Archipelago and the target of more than 50 years of conservation research and management, Galapagos giant tortoise evolution and much of their ecology remained unknown until recently. This book documents the history, the pressing conservation issues, and success stories recovering several of the 15 different species of Galapagos tortoises from near extinction.The book begins with an overview of the history of the relationship between humans and Galapagos giant tortoises, starting from initial heavy exploitation of tortoises by pirates and whalers, and extending to the start of the modern conservation era in the 1960s. The book then shifts to biology, describing Galapagos tortoise evolution, taxonomy, ecology, habitats, reproduction, and behavior. Next the decades of conservation efforts and their results are reviewed, including issues of captive breeding, invasive species, introduced diseases, and de-extinction, as well as the current status and distribution of every species. The final portion of the book turns to four case studies of restoration, and then looks ahead to the future of all tortoise populations.The latest volume in the Biodiversity of the World: Conservation from Genes to Landscape series, Galapagos Giant Tortoises is a valuable resource for researchers and conservationists, as well as students of biology, wildlife conservation, and herpetology. Provides a comprehensive overview of the Galapagos giant tortoise species as written and edited by the world’s leading experts Presents examples of restoration of tortoise populations following the near extinction of many of them Describes conservation strategies to ensure the full recovery of all extant species Explores recent efforts using replacement tortoises for extinct species to restore island ecosystems

Gullies on Mars resemble terrestrial gullies involved in the transport of abundant material down steep slopes by liquid water. However, liquid water should not be stable at the Martian surface. The articles in this volume present the two main opposing theories for Martian gully formation: climate-driven melting of surficial water-ice deposits and seasonal dry-ice sublimation. The evidence presented ranges from remote-sensing observations, to experimental simulations, to comparison with Earth analogues. The opposing hypotheses imply either that Mars has been unusually wet in the last few million years or that it has remained a cold dry desert – both with profound implications for understanding the water budget of Mars and its habitability. The debate questions the limits of remote-sensing data and how we interpret active processes on extra-terrestrial planetary surfaces, even beyond those on Mars, as summarized by the review paper at the beginning of the book.
