Scattered like dots rising from the deep across vast expanses of the world’s tropical and subtropical oceans, atolls with their turquoise lagoons and reefs teeming with colorful marine life have captured the public imagination.They have also been the homeland of millions of people for millennia as various groups of migrants spread across the far reaches if the Pacific, Indian and Western Atlantic regions.Developed from recently available satellite data, A Global Atlas of Atolls presents high-quality details of 476 atolls across the globe, characterizing aspects of the atoll rim, the lagoon, and their coral reef communities in unprecedented detail.In synthesizing and enhancing understanding of these unique seascapes, this volume provides a distinct compendium of descriptions and images, as well as documentation of the environmental conditions of winds, waves, and tides and a summary of the background literature for each atoll area.There is no comparable work. After an introduction that includes a glossary of terms, each atoll is documented in the form of an atlas written for scientists, but accessible to any diver or reader interested in these spectacular reef-island habitats.This book also describes some current challenges and perspectives on their future.It will be useful as a reference work for marine scientists, while providing a minimum of technical jargon for those who are not scientists, but who enjoy reading about exotic places with unusual attributes.
