25+ Years of Seafloor Mapping for Ecological Purposes
Department of Biological Sciences
University of New Hampshire
This presentation will be aimed at graduate students. I will briefly describe several studies I have been involved with over the years that have centered on mapping the seafloor to discern ecological processes, concluding each with questions that are still unanswered. Topics that will be covered include: the ecology of oyster reefs in Florida, how a fishing closure affected seafloor habitats in the Gulf of Maine, mapping methods and restoration of oyster reefs in New Hampshire, and mangrove and coral habitats in the United Arab Emirates.
Ray Grizzle is a Research Professor in the Department of Biological Sciences. His research program focuses on the ecology of benthic invertebrates, including those living in estuarine and shallow continental shelf habitats. Recent and current projects include bottom habitat mapping of estuarine and shallow shelf environments, the impacts of open ocean aquaculture activities on benthic communities, the ecology and culture of bivalve mollusks, and oyster reef restoration. His research also includes development of towed underwater videography for seafloor mapping and habitat characterization, and in situ fluorometry to quantify the effects of shellfish reefs on water quality.
