Dr. Donya Frank-Gilchrist presents at the Marine and River Dune Dynamics Conference in Rennes, France

Dr. Donya Frank-Gilchrist of the USGS St. Petersburg Coastal and Marine Science Center attended the Marine and River Dune Dynamics Conference (MARID), held April 3-5, 2023, that helped facilitate knowledge exchange with scientists across the world specializing in bedform dynamics in marine, riverine, and subaerial environments across a wide range of scales from small sand ripples to large dunes. MARID facilitates communication between scientists across various disciplines to improve our understanding of bedform dynamics in various environments and across a wide range of spatial and temporal scales with a focus on societal implications. 

At the conference, she presented collaborative research from USGS and the U.S. Naval Research Laboratory Ocean Sciences Division on a novel phenomenon of sediment transport: vortex trapping of sand grains by oscillatory flows over ripples. They also learned from other scientists on the state-of-the-art discoveries regarding bedform dynamics in the nearshore.
