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. dx.doi.org/10.1029/2025...

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. www.sciencedirect.com/science/arti...
