What We Do

The Popponesset Water Stewardship Alliance was formed in 2021 with the goal of addressing environmental issues facing coastal Nantucket Sound areas via citizen science projects and outreach education initiatives. We are currently studying the impacts of invasive seaweed species along coastal areas in Mashpee and Barnstable, Massachusetts, the causes and species involved in periodic jellyfish blooms, and how anthropogenic nutrient enrichment may be impacting Nantucket Sound’s coastal waters.

The ocean is the lifeblood of our world… if we were to lose some of our favorite beaches to overbuilding and pollution, then how would we feel? It’s become a case of not knowing what you’ve got until it’s gone. But by no means is it too late.
