🌊 Sediment transport + biofilm + EPS = a fascinating Virtual Science Talk this month!
Dr. Stephanie Dohner (US Naval Research Lab) and Dr. Judy Yang (U of Minnesota) are teaming up on November 19 to talk about how tiny microbes and vegetation influence massive coastal processes. bit.ly/EPSP_NOV25
Two scientific talk abstracts on a blue background with wavy topographic patterns. Top abstract titled 'EPS, EPS, every where: Noncohesive seabed evolution with ecosystem impacts' describes how exopolymeric substances (EPS) in marine environments contribute to carbon sequestration and sediment transport, focusing on biocohesion and bioturbation impacts on sediment mobility and seabed roughness through in situ and laboratory experimentation. Bottom abstract titled 'Multiscale Fluid, Sediment, and Biota Interactions in Aquatic Ecosystems' discusses using microfluidic and flume experiments to investigate biofilm dynamics, sediment transport, and hyporheic exchange, revealing how microbes and vegetation influence sediment stability, geomorphic evolution, and pollutant transport for erosion control, water quality, and ecosystem health. Bottom section contains partial speaker biographies.
