Great Lakes coasts are dynamic systems shaped by hydrological, morphodynamic, ecological, lithological, and anthropogenic processes across hours to millennia. Variations in nearshore bathymetry and shoreline morphology govern how waves, water-level fluctuations, ice, aeolian transport, and climate variability drive coastal change, ecosystem resilience, and hazard exposure. Despite their societal and environmental importance, Great Lakes shorelines remain understudied relative to marine coasts, limiting predictive and decision-ready resources. Interdisciplinary investigation is needed to assess distinctive feedbacks and controls between nearshore and onshore systems, due to the unique geology, hydrology, and seasonal ice regimes of the Great Lakes. This session welcomes studies examining the continuum of nearshore and onshore coastal processes in the Great Lakes using field observations, laboratory experiments, remote sensing, numerical modeling, machine learning, and policy-oriented approaches. Contributions linking physical change to ecological or societal outcomes, exploring understudied settings, and improving predictive understanding for management, restoration, and hazard mitigation are especially encouraged.
