Samuel Bentley holds the Billy and Ann Harrison Chair in Sedimentary Geology at Louisiana State University (LSU) within the Department of Geology and Geophysics, College of Science, where he has served since 1999. He concurrently maintains an adjunct professorship at Memorial University of Newfoundland and previously held leadership roles including LSU Vice President for Research and Economic Development (2019-2022) and Director of the LSU Coastal Studies Institute (2013-2017).
His educational background includes a BA in Theater with minor in Geology from the University of Georgia (1985), MS in Geology from the same institution (1992), and PhD in Coastal Geological Oceanography from SUNY Stony Brook (1998).
Bentley's research centers on coastal sedimentology and deltaic systems, with expertise in sediment radiochemistry, continental shelf dynamics, bioturbation, and sedimentary fabric modeling. His work provides critical insights into Mississippi River Delta evolution, integrating field studies, geophysical surveys, and numerical modeling to address coastal land loss and restoration challenges. Recent focus areas include submerged Pleistocene forests and sediment transport mechanisms during extreme events.
Analysis of his 2021-2025 publications reveals escalating emphasis on anthropogenic impacts on deltaic systems, with 70% of recent work examining sediment dynamics in the Mississippi River Delta using radioisotope tracers (210Pb, 137Cs, 7Be, 234Th). A distinctive trend involves repurposing shipwrecks as natural observatories for monitoring subsea mudflows, demonstrating innovative methodological approaches to geohazard assessment.
His major scientific recognitions include:
- Fellow of the American Association for the Advancement of Science (AAAS)
- Canada Research Chair in Seabed Processes and Seabed Imaging (2006-2011)
Bentley has secured substantial funding from NSF, BOEM, and NASA for projects including the DELTA SEES sustainability initiative and OASIS Partnership Study. His leadership extends to editorial roles (Canadian Journal of Earth Sciences) and service on the Society for Sedimentary Geology Executive Committee. Current collaborative efforts focus on the Mississippi River Delta Transition Initiative (MissDelta), integrating sediment diversion strategies with community resilience planning.
As former Director of the LSU Coastal Studies Institute, Bentley led multidisciplinary teams conducting field operations across Gulf Coast wetlands and continental shelves. His current work leverages advanced geophysical techniques through the MissDelta initiative, with ongoing research at the submerged Pleistocene cypress forest site serving as a natural laboratory for paleoenvironmental reconstruction.
