Radiocarbon dating with cosmic radiation events: problems and unexplored possibilities

This article investigates the potential of Miyake events-short-term spikes in radiocarbon production caused by cosmic radiation-for achieving single-year precision in archaeological dating. Building on recent sub-annual measurements of tree rings, we examine the implications of s...

Walrus population-specific marine reservoir offsets (ΔR) for calibration of radiocarbon dates: Implications for Arctic chronologies and medieval trade

Walruses have long played a vital role in Arctic subsistence and commercial economies, yet accurate radiocarbon dating of walrus-derived archaeological materials is complicated by regional variation in marine reservoir effects. This study presents new ΔR values derived from 31 ne...
