Tropical forest researcher 🌳 | PhD candidate @UFLA 🇧🇷 | Tree rings & stable isotopes in the Amazon | Dendroclimatology & forest-climate interactions | Climate history in wood
Thrilled to share my first thesis article in GRL! We reconstructed 131 years of Eastern Amazon wet-season rainfall using C. odorata tree-ring oxygen isotopes. This work offers a paleoclimatic perspective that is crucial for understanding the Amazon’s hydrological cycle.

Strong ENSO Forcing of Wet Season Rainfall Extremes in the Eastern Amazon
Oxygen isotopes in Cedrela odorata tree rings correlated with wet season rainfall and river discharge in the eastern equatorial Amazon The isotope proxy is used to reconstruct wet season rainfall...

What tree rings tell us about large-scale air movements. 14C records from Cameroonian trees (growing on the Northern Hemisphere) reveal that CO2 they absorb originates from other side of equator. Study lead Guaciara Santos; tree rings @petergroen.bsky.social.
