We are proud of the interdisciplinary research that has been generated at Beaubassin since our beginnings in 2009. More than 75 students have enhanced their education through research opportunities at Beaubassin. Countless others have visited the site as part of educational field trips or events by Ducks Unlimited Canada. These students have been from primarily Maritime Universities such as Acadia University, Université de Moncton, University of New Brunswick and Mount Allison University. 

Beaubassin research is broad in scope, highlighting the rich history and ecology of the area and the many opportunities it presents to those interested in understanding human interaction with environment.
