Database Structure and Content

  • The database includes luminescence and radiocarbon ages, and related geologic and geomorphic context
  • All data entries are point (not area) data and identify the site from which they are derived and have a unique identifying number (UIN)
  • All data are from published sources, including grey literature (official reports) and graduate theses and dissertations
  • Data is entered “as is”, with no interpretation. The information included in the metadata allows for interpretations and inferences.
  •  The database is searchable on the basis of multiple criteria. These include various contexts of the source site (e.g. dune type), user-defined time-slices, etc.
  • All data relate to aeolian sand deposits (e.g. sand sheets, sand ramps) or dunes, but this may include paleosol data from dune sequences, dated organic material within dune deposits, etc.
  • The data can be visualized and mapped using a GIS or on a web interface.  They are also available as a kml file for use with Google Earth. Download the .zip file and extract the kml file for viewing in Google Earth.
