Stable isotope measurements for archaeological...
The data table consists of fields organized into thematic groups. Each data entry is identified by a unique sequential key (Entry ID). The data submitter may include additional comments not covered by the existing fields (Comments), and identify the data submitter (ID submitter).
The archaeological site and sample context are described in several fields. A site name (Site name), short site description (Site description), short description of burial context (Context description), a context identifier as given in publication (Context ID), the name of the locality at which the site is located (Locality), of the corresponding region (Region), the site altitude in meters (Altitude), latitude (Latitude) and longitude (Longitude) in a WGS84 metric coordinate system, whether the location of a site could not be exactly established (Exact) and if not the range in kilometres within it is expected to be located relative to the given coordinates (Radius).
Each archaeological individual from which the sample was taken is identified using the identification provided in the original publication (Individual ID) followed by a short description of the burial (Burial type). Additional sample description includes taxon (Taxon) and the corresponding name in common language (Taxon common name). Our database currently contains only human data but in the future we plan to expand it to include other taxa. Osteological information includes sex identification (Sex), a text description of age (Age category individual), numeric ranges in years for minimum (Min. age individual) and maximum age (Max. age individual), and the type of bone or hair material that sampled from the archaeological individual (sample type).
The chronological range of the sample is given by a minimum age (Min age (95%)) and maximum age (Max age (95%)) in years BC and AD with years BC expressed by negative numbers. Age assignment followed a hierarchical approach. Whenever available we employed direct dates from samples (e.g. radiocarbon dates, in which the calibrated 95% range is reported) or from coeval samples from the same archaeological context. If necessary, corrections for aquatic radiocarbon reservoir effects were applied. If no secure dating was available from the sample context, we employed the site’s chronology given usually in the archaeological report. If this was also not available, we employed the full cultural range to which the sample was assigned. A field was used to identify the type of employed dating method (Dating method). Also included were fields for uncalibrated direct radiocarbon dates on sample (14C), its uncertainty (14C unc). Period tags are also used to provide traditional chronological information (Period tags).
Measurements of stable carbon (delta 13C coll) and nitrogen (delta 15N coll) isotopic ratios in bone collagen and hair keratin are reported together with measurements quality indicators, the percentage of elemental carbon (%C), the percentage of elemental nitrogen (%N), the carbon to nitrogen atomic ratio (C/N), and the collagen yield for bone samples (Collagen yield).
A reference in the format author(s)/year of publication/title identified the source publication or publications from where the data was collected (Reference), in addition to a link to the publication whenever available (Link), a DOI (DOI), and the publication date or dates (Publication date). Macrons were not used for Japanese titles in the list.
