Ray Grizzle researches general ecology of marine and estuarine benthic invertebrates. Most of his recent research has involved restoration of oyster reefs and oyster aquaculture in New England, including integrated farming methods for oysters and seaweeds. His laboratory also has participated in a variety of seafloor mapping projects focusing on towed underwater video, but also including sonar and other remote sensing techniques. Other research topics Professor Grizzle is able to speak to include the effects of marine protected areas on seafloor ecology and fisheries, impacts of aquaculture activities on benthic communities, and succession of fouling communities on aquaculture cages.
