A mystery eruption, solved? Uncovering an eruption that caused global temperatures to drop took geologic detective work. New research from @WillHutchGeo @univofstandrews, comments from Katharine Cashman @uoregon, story by @KatherineKornei. eos.org/articles/ice-core-re…

Ice Core Records Shed Light on a Volcanic Mystery - Eos

By analyzing sulfur and volcanic ash entrained in ice cores, researchers pinpointed a caldera in the remote Kuril Islands as the site of an unidentified 19th century eruption.

📣New paper in @pnas by Hutchison W et al. from @VICS_PAGES have revealed which mystery 🌋volcano eruption caused significant NE climate cooling from 1831–33 CE using well-dated ice cores and stratigraphic records. 👏Congratulations to the entire team! pnas.org/doi/10.1073/pnas.24…

The Beyond EPICA ice core drilling has finally reached the bedrock at a depth of 2800 m: this is a huge success for our project and for ice core science! We have strong indications that 1.2 million years of climate record are stored in the uppermost 2480 m of ice. 📸©PNRA/IPEV
