Nantucket Sound

Nantucket Sound is a roughly triangular area of the Atlantic Ocean offshore from the U.S. state of Massachusetts.

Nantucket Sound possesses significant marine habitat for a diversity of ecologically and economically important species.

"The Sound" has particular significance for several federally protected species of wildlife and a variety of commercially and recreationally valuable fisheries.

The Sound is located at a confluence of the cold Labrador Currents and the warm Gulf Stream.

Nantucket Sound has much biological diversity and contains habitats that range from open sea to salt marshes, as well as warm-water beaches on the Cape and Islands coasts.
