Overview

Comparative analysis reveals that freeze-drying improves isotopic measurements in subfossil wood, highlighting methodological implications.

Key Points

  • Freeze-drying significantly reduces oxygen isotope bias in nanocellulose from subfossil wood, enhancing climate records.
  • Isotopic analysis from freeze-dried samples shows improved homogeneity compared to oven-dried counterparts, reinforcing measurement accuracy.
  • This study provides a crucial methodological framework for climate research, focusing on cellulose-derived isotopic records in subfossil materials.
  • Ensuring isotopic fidelity is vital for reliable paleoclimate reconstructions, particularly when using cellulose as a proxy.
