Long Island Sound consists of a diverse collection of unique marine, estuarine, and terrestrial ecosystems located in one of the most densely populated regions in the United States. The Sound and its coastlines are home not only to myriad species of plants and animals--from shorebirds and turtles to whales, seals, and fish--but also to more than twenty million people.

Until now there has been no one-stop reference for those interested in exploring the Sound's rich natural history. Author, photographer, and scientific illustrator Patrick Lynch has filled this gap. Brimming with maps, photographs, and drawings, Lynch's guide introduces readers to the full breadth of the Sound's environs from shorelines to deepest waters. With coastal areas at particular risk from climate change and pollution, his timing couldn't be better. Whether readers are interested in the area's geology and meteorology, its history of human intervention, or simply locating nature reserves and bird sanctuaries, they're sure to find Lynch's compendium indispensable.
