Variable Response in Alpine Tree-Ring Stable Isotopes Following Volcanic Eruptions in the Tropics and Iceland
The importance of the stable isotopes in tree rings for the study of the climate variations caused by volcanic eruptions is still unclear. We studied δ 18 O, δD, δ 13 C stable isotopes of larch and cembran pine cellulose around four major eruptions with annual resolution, along with a superposed epo...

The importance of the stable isotopes in tree rings for the study of the climate variations caused by volcanic eruptions is still unclear.
