The TIDE Project

The TIDE project is long-term experimental ecology at the scale of the ecosystem and unique in the world.  We use an ecosystem-level approach to understand the effects of eutrophication and altered food webs on saltmarsh ecosystems in the Plum Island Estuary, Massachusetts.  We are unique because we are the only experiment in the world to maintain a long-term (10 years as of 2014), landscape-level (6 ha per plot) fertilization manipulation. The project was refunded by NSF in 2019 to study how the marsh recovers after cessation of the nutrient press.
