Nantucket Sound Won’t Stay a National Treasure Without Your Support

The Alliance to Protect Nantucket Sound is a non-profit environmental organization dedicated to the permanent preservation of Nantucket Sound.


Nantucket Sound faces many threats: coastal erosion, diminished water quality, habitat degradation, and industrial development, among others.


The Alliance is seeking federal legislation to permanently protect and preserve Nantucket Sound as well as safeguard traditional uses like fishing and recreation.


The goal of the Alliance to Protect Nantucket Sound’s education program is to spread awareness of the importance of Nantucket Sound, its unique environmental, historic and economic values, and the need to protect it for future generations.

A National Treasure

Nantucket Sound is the body of water between Cape Cod and the islands of Martha’s Vineyard and Nantucket. The Sound includes 750 square miles of federal and state waters that possess significant marine habitat for a diversity of ecologically and economically important species.
