Column Name Data Type Type Category Coding Sheet Ontology
Lower_BP Calibrated radiocarbon age of the lower position within the level excavated from the sediment column. For a level excavated between 100 and 110 centimeters below the surface (CMBS), 110 CMBS would be the lower measurement.
VARCHAR  Uncoded Value uncategorized none none
Upper_CMBS Depth of the upper position within the level excavated from the sediment column. For a level excavated between 100 and 110 centimeters below the surface (CMBS), 100 CMBS would be the upper measurement.
BIGINT  Measurement (other) uncategorized none none
Lower_CMBS Depth of the lower position within the level excavated from the sediment column. For a level excavated between 100 and 110 centimeters below the surface (CMBS), 100 CMBS would be the lower measurement.
BIGINT  Measurement (other) uncategorized none none
Height Length of the height of a best fit bounding rectangle fitted to the charcoal fragment (µm).
DOUBLE  Measurement (other) uncategorized none none
Min Minimum color value of the charcoal fragment (scale 0-255).
BIGINT  Measurement (other) uncategorized none none
Gravels_category Qualitative category assigned to each excavated sediment column level to describe the amount of alluvial gravels present. Fines refers to fine sediments with few gravels; Transitional refers to some gravels and some fines; and Gravels refers to mostly alluvial gravels.
VARCHAR  Uncoded Value uncategorized none none
Charshed_m2 Area of the charcoal source area (termed the Charcoalshed) calculated for each fragment (meters^2).
DOUBLE  Measurement (square meter) uncategorized none none
Upper_BP Calibrated radiocarbon age of the upper position within the level excavated from the sediment column. For a level excavated between 100 and 110 centimeters below the surface (CMBS), 100 CMBS would be the upper measurement.
VARCHAR  Uncoded Value uncategorized none none
Period Archaeological period associated with the charcoal fragment's position within the sediment column.
VARCHAR  Uncoded Value uncategorized none none
Morph Charcoal morphotype assigned to the charcoal fragment.
VARCHAR  Uncoded Value uncategorized none none
Solidity Solidity of the charcoal fragment (calculated as area/convex area).
DOUBLE  Measurement (other) uncategorized none none
Round Roundness of the charcoal fragment (calculated as 4*area/(π*major_axis^2)).
DOUBLE  Measurement (other) uncategorized none none
Circularity Circularity of the charcoal fragment (calculated as 4π*area/perimeter^2).
DOUBLE  Measurement (other) uncategorized none none
AR Aspect Ratio (major axis/minor axis of best fit ellipse) of each charcoal fragment.
DOUBLE  Uncoded Value uncategorized none none
Max Maximum color value of the charcoal fragment (scale 0-255).
BIGINT  Uncoded Value uncategorized none none
Width Length of the width of a best fit bounding rectangle fitted to the charcoal fragment (µm).
DOUBLE  Measurement (other) uncategorized none none
Minor Length of minor axis of a best fit ellipse fitted to the charcoal fragment (µm).
DOUBLE  Measurement (other) uncategorized none none
Major Length of major axis of a best fit ellipse fitted to the charcoal fragment (µm).
DOUBLE  Measurement (other) uncategorized none none
Perim. Perimeter of charcoal fragment (µm).
DOUBLE  Measurement (other) uncategorized none none
Feret Feret distance across charcoal fragment (µm).
DOUBLE  Measurement (other) uncategorized none none
Area Area of charcoal fragment (µm2).
DOUBLE  Measurement (other) uncategorized none none
Study_region Study region in which the column is located.
VARCHAR  Uncoded Value uncategorized none none
Fragment_Num Fragment number. Restarts at 1 for each new column sample.
VARCHAR  Uncoded Value uncategorized none none
Sample Sample number for each charcoal observation. The number is broken into four parts: Country, Region, Column Sample, Level. For example, SP_NV_11_1 refers to Spain, The Canal de Navarrés study region, column sample number 11, and level 1 (lowest level) in that column.
VARCHAR  Uncoded Value uncategorized none none
