Dr. Michael Z. Li
Conduct research in marine geology, sedimentology, and sediment transport
Current research and/or projects
Dr. Michael Li is a marine geologist and sedimentologist at the Geological Survey of Canada - Atlantic (GSCA), Dartmouth, Nova Scotia. Dr. Li is currently involved in research on wave and current processes, seabed erosion and sediment transport, and how these contribute to the nature and distribution of geohazards in the Canadian Beaufort Sea, Bay of Fundy, Scotian Shelf and Baffin Bay. His research interests have centered on three main areas: (1) wave, current and sediment transport processes in the bottom boundary layer; (2) nearbed hydrodynamics, seabed scouring, and mobility of bedforms as marine geohazards; and (3) regional hydrodynamics and sediment transport processes on continental shelves and in coastal environments through the development and application of physical and numerical models.
Research and/or project statements
- Lead scientist on investigations of oceanographic processes and seabed erosion and sediment transport as potential geohazards to oil and gas developments in the Beaufort Sea
- Project leader of a study investigating site-specific assessment of seabed stability, tidal current and sediment transport processes, and morphodynamics of large bedforms for safe and responsible development of tidal energy in the Bay of Fundy
- Led a study of seabed erosion and sediment transport during storms as well as the distribution, characteristics and mobility of bedforms on Grand Banks, to facilitate hydrocarbon developments and cross-shelf pipeline routing in the region
- Led a research component on the nearbed wave-current processes and sediment transport magnitude and frequency on the slope and upper-slope canyons of the eastern Canada margin contributing to the geoscience knowledge of geohazards and seabed constraints for safe and effective exploration and production of oil in deep-water offshore Newfoundland and Labrador.
- Project leader of the Geoscience for East Coast Offshore Developments (GECOD) project that provided sound regional knowledge of surficial geology, geohazards, foundation conditions, and other geological impediments for the safe, cost-effective, and responsible development of east coast offshore resources.
Professional activities / interests
- Provide scientific leadership in developing and maintaining cutting-edge instrumentation and computer models for sediment dynamics research
- Served as vice chair and chair and is presently the past chair of the Marine Geoscience Division of the Geological Association of Canada
- Supervisor of a post-doctoral researcher and committee member for several graduate students at Dalhousie University and University of New Brunswick
