About Us

Established in 1998, Great Pond Foundation leads in estuary science and restoration, using data generated by our programs for informed pond management. Our team builds strong partnerships with neighbors; fostering learning and expertise; and sharing tools and techniques. The coastal ponds of Martha’s Vineyard are globally rare, ecologically fragile, treasures whose preservation and restoration are fundamental to the Island’s long-term sustainability. The Island depends on clean and healthy coastal waters to feed families and support the local economy. These living waters define both the spirit and the character of our community.

Today felt like a safari as we ventured to the heads of coves of #EdgartownGreatPond. We are joined by scientists from @mblwoodshole and @sheriffsmeadow in order to identify and collect #wetland plants and assess how much and what type of #nitrogen they capture. Wetland plants 🌱 may be one of the solutions to combatting nitrogen pollution. Stay tuned 🗓️, results will be coming within the year. Preliminary data 📈 are promising. Wetlands capture both carbon and nitrogen and are good for the ponds💧 and the planet 🌏. Thanks 🙏 to our collaborators and to all those who provided access. #greatpondfoundation #marthasvineyard #greatpnd #pond #natureisthesolution #plants #boat #kayak #science #collaboration

A dead Portuguese man o’ war (Physalia physalis)  has been reported on the Edgartown Great Pond beach 🏖️, to the west of the breach area. These stinging colonial organisms show up in our waters from time to time. They are not jellyfish 🪼 but rather a siphonophore. According to @noaa “Beachcombers be warned⚠️: The stalwart man o’ war may still sting you even weeks after having washed ashore.” #beachcombers #beachcombers #beachlife #southshore #marthasvineyard #mvy #edgartown #edgartowngreatpond #beach #portugesemanofwar #siphonophore
