Description

Collection of outermost growth rings from dead wood samples, chemical pretreatment using AAA method, and accelerator mass spectrometry analysis to determine time since tree death. Calendar ages estimated by matching radiocarbon signatures to atmospheric reference curves.

Typical Equipment

  • hole saw
  • scalpel
  • tree-coring tool
  • 1 N NaOH
  • 1 N HCl
  • commercial bleach
  • sealed quartz tubes
  • vacuum line
  • accelerator mass spectrometer
  • OxCal v. 3.8 program

Output Measurements

  • 14C/12C ratios
  • Δ14C values
  • calendar year of death
