Book Description
Baja California is an improbably long and narrow peninsula. It thrusts out like a spear, parting the Mexican mainland from the Pacific Ocean. In his third installment on the Gulf of California’s coastal setting, expert geologist and guide Markes E. Johnson reveals a previously unexplored side to the region’s five-million-year story beyond the fossil coral reefs, clam banks, and prolific beds of coralline algae vividly described in his earlier books. Through a dozen new excursions, in Baja California’s Coastal Landscapes Revealed, Johnson returns to these yet wild shores to share his gradual recognition of another side to the region. Johnson reveals a geologic history that is outside the temporal framework of a human lifetime and scored by violent storms. We see how hurricanes have shaped coastal landscapes all along the peninsula’s inner coast, a fascinating story only possible by disassembling the rocks that on first appraisal seem incomprehensible. Looking closely, Johnson shows us how geology not only helps us look backward but also forward toward an uncertain future. The landscape Johnson describes may be apart from the rest of Mexico, but his expert eye reveals how it is influenced by the unfolding drama of Planet Earth’s global warming.

Book Description
Hilltops surrounded by farmland in southern Wisconsin turn out to be the eroded remnants of an ancient archipelago. An island in the Yellow Sea where Korean tourists flock is the peak of a flooded mountain rising from a drowned continental shelf. From a mountaintop shrine to Genghis Khan in Inner Mongolia, the silhouette of a Silurian seascape can be spotted. On the shores of Hudson Bay, where polar bears patrol the Arctic tundra, a close look unveils what was a tropical coastline encrusted with corals nearly 450 million years ago. The geologist Markes E. Johnson invites readers on a journey through deep time to find the traces of ancient islands. He visits a dozen sites around the globe, looking above and below today’s waterlines to uncover how landscapes of the past are preserved in the present. Going back 500 million years to the Cambrian through the Pleistocene 125,000 years ago, this book reconstructs how “paleoislands” appeared under different climatic conditions and environmental constraints. Finding vestiges of prehistoric ecologies, Johnson emphasizes the complexity of island ecosystems and the importance of preserving these significant sites. Inviting and accessible, this book is a travelogue that takes readers through time as well as space. Islands in Deep Time shares the adventure of exploring striking locations across geologic eras and issues a passionate call for their conservation.

Book Description
This book provides an overview of major changes in mainland China since the start of the modern era in 1900, as leaders grappled with how to harness natural resources requiring equal development in the pure and applied sciences based on fundamentals in geology. On one hand, China was put on the global stage with discovery of Peking Man fossils in the 1920s but has continued to win global acclaim for more recent discoveries of feathered dinosaurs and the earliest examples of metazoan life. At the same time, China struggled against outside exploitation to take full control of its own mineral and oil reserves -which today are increasingly imported from abroad to maintain oil and steel production through the Belt and Road initiative. The book concludes with a a discussion of what the ‘Chinese Dream’ may mean in comparison to what many in the United States consider as a birthright with the ‘American Dream’.

Book Description
The Gulf of California is one of the most beautiful places in the world, but it is also important to earth and marine scientists who work far beyond the area. In text and an accompanying CD-ROM with stunning satellite images, this atlas captures the dynamics of natural cycles in the fertility of the Gulf of California that have been in near-continuous operation for more than five million years. The book is designed to answer key questions that link the health of coastal ecosystems with the regionÕs evolutionary history: What was the richness of ÒfossilÓ ecosystems in the Gulf of California? How has it changed over time? Which ecosystems are most amenable to conservation? With an emphasis on the intricate workings of the Gulf, a team of scientists led by Markes E. Johnson and Jorge Ledesma-V‡zquez explores how marine invertebrates such as corals and bivalves, as well as certain algae, contribute to the operation of a vast Òorganic engineÓ that acts as a significant carbon trap. The Atlas reveals that the role of these organisms in the ecology of the Gulf was greatly underestimated in the past. The organisms that live in these environments (or provide the sediments for beaches and dunes) are mass producers of calcium carbonate. Until now, no book has considered the centrality of calcium carbonate production as it functions today across multiple ecosystems and how it has evolved over time. An important work of scholarship that also evokes the regionÕs natural splendor, the Atlas will be of interest to a wide range of scientists, including geologists, paleontologists, marine biologists, ecologists, and conservation biologists.

Book Description
Baja California: wild, desolate, and a treasure-house of geological wonders. Along its ancient shorelines, careful observers can learn much about how the Gulf of California came into existence and what the future of the Baja California peninsula might be. For those who wish to unlock the mysteries of Baja California, geologist Markes Johnson offers the key. He has taken a body of technical research on the geology and paleontology of the region and made it accessible in plain language for anyone who visits the peninsula, whether for study or recreation. His book teaches general concepts in coastal geomorphology and tectonics, as well as the basic geological and natural history of the Gulf of California, in a conversive, intellectually stimulating fashion. Johnson's guide takes the form of six day-long hikes in the area of Punta Chivato on the east coast of the southern Baja California peninsula. Punta Chivato is presented as a microcosm of the entire region; it can enable visitors to better understand major themes in the natural history of the Gulf of California and its geological past. All of the hikes begin at the southeast corner of the Punta Chivato promontory and loop out in different directions. Each circuit is designed to minimize overlap with adjacent hikes and to maximize the visitor's exposure to instructive variations in the landscape. Each chapter features additional reflections on a geologist of another time and place who has advanced the field in a way that elucidates the material covered in that chapter. Through these asides, readers will learn the basic lessons about how geologists read the secrets hidden in landscapes. Discovering the Geology of Baja California invites visitors to these shores to explore not only rocks and fossils but also the continuum of past ecosystems with the ecology of the present. It offers both an unparalleled guide to a remote area and a new understanding of life caught in an endless cycle of change.

Book Description
The Pacific of the early eighteenth century was not a single ocean but a vast and varied waterscape, a place of baffling complexity, with 25,000 islands and seemingly endless continental shorelines. But with the voyages of Captain James Cook, global attention turned to the Pacific, and European and American dreams of scientific exploration, trade, and empire grew dramatically. By the time of the California gold rush, the Pacific's many shores were fully integrated into world markets-and world consciousness. The Great Ocean draws on hundreds of documented voyages--some painstakingly recorded by participants, some only known by archeological remains or indigenous memory--as a window into the commercial, cultural, and ecological upheavals following Cook's exploits, focusing in particular on the eastern Pacific in the decades between the 1770s and the 1840s. Beginning with the expansion of trade as seen via the travels of William Shaler, captain of the American Brig Lelia Byrd, historian David Igler uncovers a world where voyagers, traders, hunters, and native peoples met one another in episodes often marked by violence and tragedy. Igler describes how indigenous communities struggled against introduced diseases that cut through the heart of their communities; how the ordeal of Russian Timofei Tarakanov typified the common practice of taking hostages and prisoners; how Mary Brewster witnessed first-hand the bloody "great hunt" that decimated otters, seals, and whales; how Adelbert von Chamisso scoured the region, carefully compiling his notes on natural history; and how James Dwight Dana rivaled Charles Darwin in his pursuit of knowledge on a global scale. These stories--and the historical themes that tie them together--offer a fresh perspective on the oceanic worlds of the eastern Pacific. Ambitious and broadly conceived, The Great Ocean is the first book to weave together American, oceanic, and world history in a path-breaking portrait of the Pacific world.
