"Sea level is rising, and yet Americans continue to develop beaches with little regard. In this volume, a group of coastal geologists discusses the startling saga of ten U.S. East and Gulf Coast shoreline communities (plus Puerto Rico and some western Europe strands) and the problems created by their inevitable interaction with natural processes in this highly dynamic geologic environment. The authors discuss the geologic context of the hazards of each site as the history of societal responses and their environmental impacts. Response to the natural coastal processes that threaten lives and buildings is carried out in a context of local, state and national politics with fixed short-term engineering solutions (beach replenishment, seawalls) generally favored over longer-term approaches (moving back, prohibition of seawalls). This essential GSA Special Paper foreshadows the impending rise of sea level and the myriad of shoreline responses and political controversies it will provoke."--Publisher's description.

At the coast all is not what it seems. Decades of beachfront development have seen a variety of efforts to stabilize the shoreline to protect ill-placed beachfront property, both from shoreline erosion and from storm damage. Both of these problems become increasingly critical in a time of rising sea level. Many natural beaches are backed by sea walls, while others have been transformed by whole series of groynes, offshore breakwaters and a plethora of other schemes. Many recreational beaches are actually artificial replicas of the real thing, emplaced to protect badly placed infrastructure and maintained only through ongoing costly beach nourishment. However, all of these attempts to stabilize the shoreline are far from benign. Degradation and even complete loss of the all important recreational beach sometimes results from seawall emplacement. Increasingly, the choice of shoreline stabilization approach will depend upon plans for future response to rising seas which in many cases may involve retreat from the shoreline rather than holding the line. This book explores, through a series of case studies from around the globe, the pitfalls of shoreline stabilization and provides a ready reference for those with an interest in shoreline management. It is particularly timely in a time of global change.

We live in a world where the loss of sea ice and thawing of coastal grounds in the north, and renewed marine transgression and an increase in the frequency of extreme weather events globally, are becoming commonplace. This volume presents a timely examination of coasts, the geological environment at particular risk, as global warming brings on this new reality. In 23 papers, low lying, mainly siliciclastic coasts are reviewed, described and analysed, under a variety of climates in quasi-stable tectonic settings along passive, trailing-continental edges from Polar Regions to the Tropics. Examples include coast of the Arctic seas, temperate to tropical eastern shores of the Americas, western Portugal, Mediterranean, Persian Gulf, South Africa and Australia. The entire coastal zone (landscape) is considered ranging from geophysical processes and products to biological entities including the adaption of Native People in various climatic zones. Knowledge of the state of the coasts now, and how the coastal plain has evolved since Late Pleistocene, is crucial for any realistic planning for the future.

Measuring sea-level change – be that rise or fall – is one of the most pressing scientific goals of our time and requires robust scientific approaches and techniques. This Handbook aims to provide a practical guide to readers interested in this challenge, from the initial design of research approaches through to the practical issues of data collection and interpretation from a diverse range of coastal environments. Building on thirty years of international research, the Handbook comprises 38 chapters that are authored by leading experts from around the world. The Handbook will be an important resource to scientists interested and involved in understanding sea-level changes across a broad range of disciplines, policy makers wanting to appreciate our current state of knowledge of sea-level change over different timescales, and many teachers at the university level, as well as advanced-level undergraduates and postgraduate research students, wanting to learn more about sea-level change.

The Last Beach is an urgent call to save the world's beaches while there is still time. The geologists Orrin H. Pilkey and J. Andrew G. Cooper sound the alarm in this frank assessment of our current relationship with beaches and their grim future if we do not change the way we understand and treat our irreplaceable shores. Combining case studies and anecdotes from around the world, they argue that many of the world's developed beaches, including some in Florida and in Spain, are virtually doomed and that we must act immediately to save imperiled beaches. After explaining beaches as dynamic ecosystems, Pilkey and Cooper assess the harm done by dense oceanfront development accompanied by the construction of massive seawalls to protect new buildings from a shoreline that encroaches as sea levels rise. They discuss the toll taken by sand mining, trash that washes up on beaches, and pollution, which has contaminated not only the water but also, surprisingly, the sand. Acknowledging the challenge of reconciling our actions with our love of beaches, the geologists offer suggestions for reversing course, insisting that given the space, beaches can take care of themselves and provide us with multiple benefits.

The World of the Salt Marsh is a wide-ranging exploration of the southeastern coast—its natural history, its people and their way of life, and the historic and ongoing threats to its ecological survival. Focusing on areas from Cape Hatteras, North Carolina, to Cape Canaveral, Florida, Charles Seabrook examines the ecological importance of the salt marsh, calling it “a biological factory without equal.” Twice-daily tides carry in a supply of nutrients that nourish vast meadows of spartina (Spartina alterniflora)—a crucial habitat for creatures ranging from tiny marine invertebrates to wading birds. The meadows provide vital nurseries for 80 percent of the seafood species, including oysters, crabs, shrimp, and a variety of finfish, and they are invaluable for storm protection, erosion prevention, and pollution filtration. Seabrook is also concerned with the plight of the people who make their living from the coast’s bounty and who carry on its unique culture. Among them are Charlie Phillips, a fishmonger whose livelihood is threatened by development in McIntosh County, Georgia, and Vera Manigault of Mount Pleasant, South Carolina, a basket maker of Gullah-Geechee descent, who says that the sweetgrass needed to make her culturally significant wares is becoming scarcer. For all of the biodiversity and cultural history of the salt marshes, many still view them as vast wastelands to be drained, diked, or “improved” for development into highways and subdivisions. If people can better understand and appreciate these ecosystems, Seabrook contends, they are more likely to join the growing chorus of scientists, conservationists, fishermen, and coastal visitors and residents calling for protection of these truly amazing places.

This sobering examination of climate-change and the disastrous effects of rising sea levels explains what must be done to avoid the worst outcomes. By the end of this century, hundreds of millions of people living at low elevations along coasts will be forced to retreat to higher and safer ground. Because of sea-level rise, major storms will inundate areas farther inland and will lay waste to critical infrastructure, such as water-treatment and energy facilities, creating vast, irreversible pollution by decimating landfills and toxic-waste sites. Retreat from a Rising Sea explains in gripping terms what rising oceans will do to coastal cities—detailing the specific threats faced by Miami, New Orleans, New York, and Amsterdam. This policy-oriented book then lays out the drastic actions we must take now to remove vulnerable populations. Aware of the overwhelming social, political, and economic challenges that would accompany effective action, the authors consider the burden to the taxpayer and the logistics of moving landmarks and infrastructure, including toxic-waste sites. They also show readers the alternative: thousands of environmental refugees, with no legitimate means to regain what they have lost. The authors conclude with effective approaches for addressing climate-change denialism and powerful arguments for reforming U.S. federal coastal management policies.

Take this book to the beach; it will open up a whole new world. Illustrated throughout with color photographs, maps, and graphics, it explores one of the planet’s most dynamic environments—from tourist beaches to Arctic beaches strewn with ice chunks to steaming hot tropical shores. The World’s Beaches tells how beaches work, explains why they vary so much, and shows how dramatic changes can occur on them in a matter of hours. It discusses tides, waves, and wind; the patterns of dunes, washover fans, and wrack lines; and the shape of berms, bars, shell lags, cusps, ripples, and blisters. What is the world’s longest beach? Why do some beaches sing when you walk on them? Why do some have dark rings on their surface and tiny holes scattered far and wide? This fascinating, comprehensive guide also considers the future of beaches, and explains how extensively people have affected them—from coastal engineering to pollution, oil spills, and rising sea levels.

This book presents chapters, written by leading coastal scientists, which collectively depict the current understanding of the processes that shape barrier islands and barrier spits, with an emphasis on the response of these landforms to changing conditions. A majority of the world’s population lives along the coast at the dynamic intersection between terrestrial and marine ecosystems and landscapes. As narrow, low-lying landforms, barriers are especially vulnerable to changes in sea level, storminess, the geographic distribution of grass species, and the rate of sand supply—some barriers will undergo rapid changes in state (e.g., from landward migrating to disintegrating), on human time scales. Attempts by humans to prevent change can hasten the loss of these landforms, threatening their continued existence as well as the recreational, financial and ecosystem service benefits they provide. Understanding the processes and interactions that drive landscape response to climate change and human actions is essential to adaptation. As managers and governments struggle to plan for the future along low-lying coasts worldwide, and scientists conduct research that provides useful guidance, this volume offers a much-needed compilation for these groups, as well as a window into the science of barrier dynamics for anyone who is generally interested in the impacts of a changing world on coastal environments.
