abstract

  • The Port Royal Bay sediments provide an excellent record of Holocene deposition in a low fluid power marine carbonate environment and are a particularly good indicator of sea-level changes. Seismic surveying and radiocarbon dating of material recovered by vibracore allow interpretation of sub-bottom stratigraphy and basin evolution with sea-level rise. The sedimentary record shows that rising sea levels alowed a marsh to develop approximately 9500 years ago over older, red soils which existed in the lower levels of the Port Royal Basin. By 8200 yrs B.P., the marsh or swamp had been replaced by a pond in the central area of the basin. Ocean water invaded the bay about 7000 yrs B.P. to produce a marine environment, which has allowed extensive development of the coral Oculina and other marine associations above the submerged swamp and pond deposits. © 1984.
