Evolution of Depositional Patterns in the Mississippi Sound During the Late Holocene

Brian M. Velardo, Samuel J. Bentley

Abstract

Modern facies analysis of vibracores collected north of Cat Island and Ship Island provides a history of the evolution of the Mississippi Sound during the past 1000 years. Vibracores, collected in May 2003, were analyzed using radioisotope geochronology (137Cs and 210Pb), x-radiography, granulometry, and a multi-sensor core logger. Sediments collected were characterized as belonging to two groups of lithofacies: 1) open bay and 2) nearshore. North-south cross sections north of Cat Island and Ship Island document an evolution in the sedimentary facies with time. Facies distributions appear to vary in space and time, suggesting that fluctuations in sea level, sediment delivery and accumulation, and the migration of the barrier islands have influenced the depositional environments surrounding the barrier islands.
