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.

Maine is known for its rockbound coast and pristine shoreline. Yet there is more to this shore than rocky cliffs. This book describes the origin of the more common "soft coast" of eroding bluffs, sand beaches, and salt marshes. A central theme is the formation of the present shoreline during the current ongoing rise in sea level and the ways in which coastal residents can best cope with the changes to come. Although it is not widely known, Maine is experiencing a rapid, uneven drowning of its shore at the same time that coastal development is at an all-time high. The authors explain how the shoreline is changing and provide a series of highly detailed maps that show the relative safety of particular locations on the coast.Specific guidelines for recognizing various safe and unsafe coastal settings are presented, as are recommendations for sound construction techniques in hazardous coastal areas. Photographs and drawings illustrate the danger of living too near the shoreline, and an up-to-date review of Maine's regulations governing coastal construction is simply and readably described. A bibliography of important coastal literature is also included, as well as a guide to federal, state, and local sources of information.
