Research Description:
My research over the past decade has focused on the application of acoustic survey methods (multibeam sonar, sidescan sonar, single beam acoustics) for studying, mapping and monitoring benthic ecosystems. My work focuses on using environmental data sets (primarily derived from acoustic sources) to improve our understanding of the spatial ecology of the seafloor. My current research is focusing on extracting quantitative data from acoustic backscatter from multibeam sonar systems for use in species, community and habitat distribution modeling. Other research interests: Benthic monitoring methodology; Seafloor habitat modeling; Hard-substrata ecology; the ecology of artificial reef.
