The study area\r\nincludes vibracore samples from the Southern Outer Banks, both \r\nnorth and south of Cape Lookout, NC, and vibracore samples from \r\nOnslow Bay, southwest of Cape Lookout.  Additional samples from \r\nonshore sites southwest of Cape Fear and from subsurface sites \r\nin Dare County, NC are used for comparison with the Cape Lookout \r\nresults.  Core samples have been obtained by researchers at Duke \r\nUniversity, the University of South Florida, the US Geological \r\nSurvey, East Carolina University, and the University of Delaware.  \r\nMultiple aminozones are identified in the region, representing \r\nages from early, middle, and late Pleistocene.  All aminozones \r\nare recognized within the suite of cores from the Cape Lookout \r\narea, but there is a notable absence of most of the mid- to \r\nlate-Pleistocene aminozones from the area south-southwest of \r\nCape Fear. These observations suggest that the late Quaternary \r\nrecord is quite incomplete in the region of the Cape Fear Arch.","author":null,"citation":"York, L.L. and J.F.
