This volume offers a treatment of radiative transfer theory in a format tailored to the specific needs of optical oceanography, with applications to real problems. It develops the basic theory and reviews the current literature. Numerical methods for solving radiative transfer equations are then detailed, with equations describing transpectral effects, internal surfaces, and surface effects. Equations governing the propagation of visible light across air-water surfaces and within water bodies are also explained.

An examination of the lingering effects of a hydroelectric power station on Pimicikamak sovereign territory in Manitoba, Canada. The child of South Asian migrants, Kazim Ali was born in London, lived as a child in the cities and small towns of Manitoba, and made a life in the United States. As a man passing through disparate homes, he has never felt he belonged to a place. And yet, one day, the celebrated poet and essayist finds himself thinking of the boreal forests and lush waterways of Jenpeg, a community thrown up around the building of a hydroelectric dam on the Nelson River, where he once lived for several years as a child. Does the town still exist, he wonders? Is the dam still operational? When Ali goes searching, however, he finds not news of Jenpeg, but of the local Pimicikamak community. Facing environmental destruction and broken promises from the Canadian government, they have evicted Manitoba’s electric utility from the dam on Cross Lake. In a place where water is an integral part of social and cultural life, the community demands accountability for the harm that the utility has caused. Troubled, Ali returns north, looking to understand his place in this story and eager to listen. Over the course of a week, he participates in community life, speaks with Elders and community members, and learns about the politics of the dam from Chief Cathy Merrick. He drinks tea with activists, eats corned beef hash with the Chief, and learns about the history of the dam, built on land that was never ceded, and Jenpeg, a town that now exists mostly in his memory. In building relationships with his former neighbors, Ali explores questions of land and power?and in remembering a lost connection to this place, finally finds a home he might belong to.

A graceful, elegant account even when reporting on the hard truths of a little-known corner of the world.” —Kirkus Reviews “[Ali’s] experiences are relayed in sensitive, crystalline prose, documenting how Cross Lake residents are working to reinvent their town and rebuild their traditional beliefs, language, and relationships with the natural world. . . . Though these topics are complex, they are untangled in an elegant manner.” —Foreword Reviews (starred review)

Several general books are available on ultraviolet light and its applications. However, this is the first comprehensive monograph that deals with its application to water and wastewater treatment. There is a rapidly growing interest in using UV light in water sanitation due to the increased knowledge of the potential health and environmental impacts of disinfection byproducts. Ultraviolet Light in Water and Wastewater Sanitation integrates the fundamental physics applicable to water and wastewater sanitation, the engineering aspects, and the practical experience in the field. The text analyzes the concerns associated with this application of UV light and brings together comprehensive information on the presently available UV technologies applicable to water and wastewater treatment including: lamp technologies, criteria of evaluation and choice of technology; fundamental principles; performance criteria for disinfection; design criteria and methods; synergistic use of UV and oxidants (advanced oxidation); and functional requirements and potential advantages and drawbacks of the technique. Ultraviolet Light in Water and Wastewater Sanitation is the only treatise currently available combining fundamental knowledge, recommendations for design, evaluations of performance, and future prospects for this application. Water and wastewater treatment professionals, water utility employees, governmental regulators, and chemists will find this book an essential and unique reference for a technology which has received growing regulatory acceptance.

The New York Times–bestselling author’s memoir of diving in the Caribbean offers “in precise, lucid, prose, the marvels of the sea bottom” (New Yorker). Author Stephen Harrigan spent months diving on the coral reefs of Grand Turk Island in the Caribbean. In this evocative account, he describes his many explorations, both personal and natural. Though he is there to learn about the history of the coral reef, Harrigan freely admits that his true motivation is to become, at least for a time, his “underwater self.” “Moving, intelligent and, in the best sense, literary. . . . Stephen Harrigan is anchored in reality; he knows that the environment he's describing is in serious jeopardy. At the same time, he has made this book sparkle with his remarkable ability to discuss the metaphysical and spiritual aspects of underwater exploration without ever sounding saccharine or murky.” —New York Times Book Review
