The purpose of this book is to bring together in one volume a comprehensive body of work regarding the creation of underwater archaeological preserves, parks, and trails throughout the world. The book relates the continuing progress made by agencies and institutions that have sponsored these kinds of projects for over twenty years, as well as by those just beginning to introduce the concept in their region. Themes discussed in this work include historic preservation, tourism, education, and recreation, to name a few. This volume should be considered a primer for underwater archaeologists, both professional and avocational, and submerged cultural resource managers who wish to embark on encouraging and enhancing public access to suitable underwater archaeological sites. Additionally, this compilation will be of relevance to anyone interested in this concept as a form of historic preservation and, as a sort of travel guide, to those intent on descending into the water to visit the relics or to those wishing to learn more about a region's maritime cultural legacy.
