Glaciated Coasts is a collection of articles that deals with shoreline morphologies of glaciated coasts and the processes that formed these coastlines in North America. This book examines nonsandy shorelines and covers a range of geologic and geographic coastal settings in a northern-southern order. This text investigates and compares the glaciated northern shorelines. These shorelines north of the glacial limit are mostly of the primary form in different stages of modification by marine agents. Shorelines are associated with embayments; baymouth barriers in turn enclose embayments. This book describes beaches as having coarse or mixed sediment populations. Most beaches worldwide have gravel clasts that have been rounded and sorted by marine processes. In the southeastern coast of Alaska, active tectonics on a mountainous shoreline is evident. The region also shows emergent and submerging shorelines with a glacial imprint undergoing formation by modern processes. This book also gives examples of gravel beach environments in various coastal settings. This book can prove useful for students of meteorology, oceanography as well as to marine ecologists and biologists. It can also benefit readers whose interest lie with coastal environment or with the general earth sciences.
