Abstract
Open-File Report 50 presents and describes a database of geochronological information for coastal deposits of the US Atlantic and Pacific coasts, as well as for sites from the Pacific coast of South America. This database represents a synthesis of nearly forty years of study conducted by John F. Wehmiller and students in the Department of Geological Sciences, University of Delaware, as well as many collaborating colleagues. The majority of the chronological information in the database is based on amino acid racemization (AAR) data for fossil mollusks obtained from over 1000 collection sites. These chronological data have been used for various mapping, paleoenvironmental, stratigraphic, sea-level, and tectonic studies. In addition to the database itself, 18 on-line supplements containing information related to sample descriptions, sample and collection site photographs, field notes, supporting or related analytical data, and laboratory publications and technical reports are available. Periodic updates and additions will be made where appropriate. The database will be updated regularly to add new data or to complete entries that are currently blank. The instructions provided with the database indicate the date of the latest revision, as well as all revisions after the first release. Some output data from the Amino Acid Racemization Data Base (AARDB) are available at on-line mapping sites or are posted to the NOAA-World Data Center for archival preservation (http://www.ncdc.noaa.gov/paleo/aar.html).
