Sub-annual bomb radiocarbon records from trees in northern Israel

Spatial and temporal variations in the atmospheric bomb radiocarbon make it a very useful tracer and a dating tool. With the introduction of more atmospheric bomb radiocarbon records, the spatial and temporal changes in bomb radiocarbon are becoming clearer. Bomb radiocarbon record from a pine tree in the northern Israel region shows that the Δ¹⁴C level in the region is closer to the northern hemisphere zone (NH) 1 as compared to the northern hemisphere zone (NH) 2. A comparison of this pine's Δ¹⁴C record with a nearby olive tree's Δ¹⁴C values also highlights changes in the growing season of the olive wood from one year to the other. The observation suggests that olive wood ¹⁴C ages can show offset compared to the IntCal curve, and thus they should be interpreted cautiously.
