💦 New paper from our group out on the modern isotopic variability of Icelandic lake and soil water. Excited to apply this framework in lake seds to explore paleohydrological changes in the middle of the North Atlantic! hess.copernicus.org/articles/28/...

Spatiotemporal variation of modern lake, stream, and soil water isotopes in Iceland

Abstract. As global warming progresses, changes in high-latitude precipitation are expected to impart long-lasting impacts on Earth systems, including glacier mass balance and ecosystem structures. Re...

They keep giving us more to think about, which is fun! On the “optimistic” side, I’m curious if our results suggest we can develop new proxies for nitrate and water column strat and highly stratified polar regions like Iceland 🙃

New paper from Julio and I on marine OH-GDGTs around Iceland. TL;DR nitrate concentrations and water-column stratification are best correlated to OH-GDGT distributions, and not temperature (at least for Iceland...) www.frontiersin.org/journals/ear...

Stoked to finally have this piece out. Ran the first tephra samples 9 years ago at the beginning of my PhD @Haskoli_Islands. TL;DR: Multiple, younger Vedde-like tephra layers are now also present in Iceland. Be cautious with your North Atlantic age models! rdcu.be/dsLRT
