<p>Dr. Jenn Dijkstra is a Research Associate Professor the Center for Coastal and Ocean Mapping. Dr. Dijkstra was the University member representative on the New Hampshire commission for Coastal Marine Natural Resources and Environment. She is the chair of the Diving Control Board.</p>

<p>Broadly, we characterize the benthic environment (seafloor, including foundation and non-native species, and demersal fishes) communities using a combination of remote sensing (e.g., active acoustics (echosounders), unmanned aerial imagery, ground-truth, photogrammetry) and in-situ observations (diver surveys) and experiments. We study communities that span the deep sea to kelp forests and warm water coral reefs. This includes the study of changes in community composition, biogenic structure of reefs (temperate and coral), and relationships between bathymetry and species composition.</p>
