Science Notes – Oxygen isotope tree-ring dating at the Tower of London

Dendrochronology (dating timbers by analysing tree-rings) is a vital weapon in the archaeological arsenal, and one that is often mentioned in CA. This month’s ‘Science Notes’ features a new approach, using stable isotopes, which could help date samples that cannot normally be analysed using traditional methods. We will be looking at how this method was able to shed light on the history of construction at the Tower of London.
