ABSTRACT Billy, J.; Robin, N.; Hein, C.; FitzGerald, D., and Certain, R., 2018. Dominance of inherited geologic framework on the development of coastal barrier system. In: Shim, J.-S.; Chun, I., and Lim, H.S. (eds.), Proceedings from the International Coastal Symposium (ICS) 2018 (Busan, Republic of Korea).

Many coastal systems are influenced by geologic framework (e.g., bedrock or inherited sedimentary systems), either in their initial development, morphology, or continuously throughout their evolution. This study adds to our understanding of the role of bedrock inheritance by describing the evolution of the Miquelon-Langlade Barrier (NW Atlantic; France). This barrier has a complex coastal planform (Y-shape, 12-km-long, 100–2500-m-wide) with several embedded sedimentary landforms. Ground-penetrating radar and HR seismic data collected along the subaerial and subaqueous portions of the barrier reveal:...
