NANTUCKET SOUNDKEEPER
The Nantucket Soundkeeper program provides for the long-term protection and preservation of Nantucket Sound. Designated the official steward of the Sound by the Waterkeeper Alliance in 2009, the Soundkeeper program aims to preserve the water's unique qualities through advocacy and public education.
The mission of Nantucket Soundkeeper is to serve as the advocate for the marine waters bounded by Cape Cod, Nantucket and Martha’s Vineyard. Our motto is "Protect Today, Preserve Forever."
Through water quality monitoring, educational programs and outreach to the local community, our goal is to inform the citizens of Cape Cod and the Islands about how to become stewards of the Sound and to advocate for its long-term protection.
The cold Labrador Current and warm Gulf Stream converge in Nantucket Sound, bringing together northern and southern species of marine life and creating an extreme richness of biological diversity and productivity.
