Ellen Kenchington, PhD
Dr. Kenchington's role is to provide scientific advice on issues related to benthic species and habitats both nationally and internationally. Her research focuses on the benthic ecology of the continental shelf and slopes, biodiversity, impacts of fishing and climate change on benthic communities, and population genetics of marine organisms. Outcomes of her research contribute to identification of vulnerable marine ecosystems (VMEs), ecologically or biologically significant areas (EBSAs), marine protected area selection and design, and sustainable fishing practices.
Current research and/or projects
As a benthic ecologist, Dr. Ellen Kenchington studies the organisms which live on or in the seafloor. She works to deepen our understanding of their relationship with the sediment and the seabed structure they are found on, as well as the overlying water masses which may control their distributions. Her research takes place primarily on the continental shelves and slopes and in water depths of up to 3,000 meters or more. The research relies on large-scale habitat mapping, seabed mapping and water mass characteristics to be able to predict the distribution of organisms important in the marine ecosystem, such as deep-water coral and sponge beds. Domestically she has provided scientific support for the Policy for Managing the Impact of Fishing on Sensitive Benthic Areas and contributed to the establishment of the first area closure under that policy. Recently she has been working to establish benthic biodiversity monitoring sites in the Canadian Arctic in support of the Arctic Council’s Circumpolar Biodiversity Monitoring Plan and to model benthic species distributions in the northwest Atlantic.
Watch as Ellen explains her work in understanding organisms that live in deep waters.
