The Grizzle Laboratory

Our home is the University of New Hampshire's Jackson Estuarine Laboratory, an off-campus research facility located on the shore of the Great Bay Estuary. Most of our work deals with the ecology of invertebrates living on the seafloor, including those in estuarine and shallow continental shelf habitats. Since 2000, a major effort has been oyster reef restoration projects ranging from small experimental "mini-reefs" to full-scale restoration of natural reefs. Recently, we have conducted research projects on integrated farming methods for oysters and seaweeds, and the roles that oyster farms as well as natural reefs play in nutrient processing. Our capabilities also include: seafloor mapping using towed underwater video systems, sonar, and satellite imagery; assessing the effects of marine protected areas on seafloor ecology; assessing the impacts of aquaculture activities on benthic communities; characterizing the succession of fouling communities on marine aquaculture cages, particularly in the context of anti-fouling properties of coatings and paints; and developing new methods for quantifying oyster reef water filtration rates. In addition to New Hampshire, we have been involved in research and contract projects in New York, North Carolina, South Carolina, Georgia, Florida, and the United Arab Emirates.

We regularly partner with scientists from other institutions, and it is these collaborations that allow us to maintain capabilities across a wide range of coastal issues and research topics.
