Uptake of Carbon for Cellulose Production in a White Oak from Western Oregon, USA
Published online by Cambridge University Press: 08 November 2017
Abstract
We report ∆14C measurements of cellulose extracted from near monthly tree ring growth for the 1960s of a white oak that grew in western Oregon, USA. Comparison with ∆14C measurements of atmospheric CO2 reveals that the tree ring ∆14C values were equal to or lower than those in atmospheric CO2 at the time of ring formation. We suggest that the low tree ring ∆14C values during the period 1962–1963 were caused by the presence of an atmospheric front or blocking between subpolar and temperate air masses that delayed the arrival of the bomb signal at the tree’s site.
