Pacific Northwest Coastal Environments: Earthquakes and Sea Level Rise investigates the potential impacts of changes in global sea level by examining historical sea and land levels, projected future levels, and by determining how those changes may affect future tides and storm surges to inform their potential to cause harmful impacts. This region has a unique interaction of land, sea, and tectonics. Climate and tectonic change can initiate issues ranging from an inundation of coastal areas due to a combination of sea level rise, vertical land movement, and potential tsunami. This combination of factors leads to the retreat of coastal shorelines due to erosion caused by both tidal action and wave runup. Specific topics explored in this book include the following: Coastal erosion rates along the Pacific Northwest coastline from Eureka, California to Vancouver Island, British Columbia. Sea cliff retreat mitigation techniques looking at both the advantages and disadvantages of the different techniques. Interaction between subduction zone earthquakes and vertical land movement. Wave characterization in both deep and shallow water. In addition, the book looks at both wave refraction and reflection along the coastline. Tides along the Pacific Northwest coastline and their role in calculating the relative sea level and its effect on coastal erosion.

While the coast of the Pacific Northwest becomes ever more populated and developed, its beaches and cliffs continue to be altered by ocean currents and winter storms. Coastal oceanographer Paul Komar reminds readers of the area's geological and cultural history and the ever-present problem of erosion. He issues an urgent call for changes in shoreline management and attitudes toward development. 41 figures. 20 maps. 112 photos.

“Part field guide, part travel guide, Steelquist writes with the authoritative voice of that friend you want next to you on the trail or in the dunes—the one who knows just where to go for a weekend getaway and what to pack for the Pacific Northwest’s unpredictable weather.” —Portland Monthly Millions of visitors explore the magnificent coastline of the Pacific Northwest and all that it provides—unique plant life, easy-to-find animals, and magical places. The Northwest Coastal Explorer is a fun, engaging, lushly-illustrated guide to the marine life of Oregon, Washington, and British Columbia. Profiles of the flora and fauna include tips on where and how to find them—like the ochre sea stars commonly discovered on exposed rocks and the olive snails found on sandy beaches—while the included getaway guide highlights the best weekend trips for each area.

The Pacific Northwest coast is home to one of the most diverse displays of intertidal marine life in the world, including sponges, clams, snails, crabs, sea stars, sea anemones, jellies, fishes, seaweeds and more. The New Beachcomber’s Guide to the Pacific Northwest is a portable and easy-to-use reference for searching out and identifying the hundreds of species of seashore life found on the beaches of British Columbia, Washington, Oregon, Northern California and Southeast Alaska. Covering the Pacific Northwest’s most common shoreline-dwelling flora and fauna, the guide gives in each entry a detailed description of appearance and habitat accompanied by colour photos for easy identification of any creature you might encounter as you explore your local beach. Simple but essential information on tides and the various habitats within the intertidal zones is also provided to assist beachcombers in exploring safely with minimal ecological impact. The New Beachcomber’s Guide even contains up-to-date descriptions of the best beachcombing sites and when to visit them—you may even find your new favourite exploration grounds! Thoroughly revised and packed with handy and accessible information, this guide belongs in the beach bag or backpack of any avid naturalist, amateur beachcomber or adventurous family.

It can be said that all of human history is environmental history, for all human action happens in an environment—in a place. This collection of essays explores the environmental history of the Pacific Northwest of North America, addressing questions of how humans have adapted to the northwestern landscape and modified it over time, and how the changing landscape in turn affected human society, economy, laws, and values. Northwest Lands and Peoples includes essays by historians, anthropologists, ecologists, a botanist, geographers, biologists, law professors, and a journalist. It addresses a wide variety of topics indicative of current scholarship in the rapidly growing field of environmental history.

Tide gauges show that global sea level has risen about 7 inches during the 20th century, and recent satellite data show that the rate of sea-level rise is accelerating. As Earth warms, sea levels are rising mainly because ocean water expands as it warms; and water from melting glaciers and ice sheets is flowing into the ocean. Sea-level rise poses enormous risks to the valuable infrastructure, development, and wetlands that line much of the 1,600 mile shoreline of California, Oregon, and Washington. As those states seek to incorporate projections of sea-level rise into coastal planning, they asked the National Research Council to make independent projections of sea-level rise along their coasts for the years 2030, 2050, and 2100, taking into account regional factors that affect sea level. Sea-Level Rise for the Coasts of California, Oregon, and Washington: Past, Present, and Future explains that sea level along the U.S. west coast is affected by a number of factors. These include: climate patterns such as the El Niño, effects from the melting of modern and ancient ice sheets, and geologic processes, such as plate tectonics. Regional projections for California, Oregon, and Washington show a sharp distinction at Cape Mendocino in northern California. South of that point, sea-level rise is expected to be very close to global projections. However, projections are lower north of Cape Mendocino because the land is being pushed upward as the ocean plate moves under the continental plate along the Cascadia Subduction Zone. However, an earthquake magnitude 8 or larger, which occurs in the region every few hundred to 1,000 years, would cause the land to drop and sea level to suddenly rise.
