Congrats to @yasmeenorellana.bsky.social on her first lead-author paper, out now in Quaternary Science Reviews! Check it out to learn about Holocene alpine ice position at Villarrica Volcano, Chile! #Geochronology #CosmogenicNuclides #Climate #Glaciers #Holocene www.sciencedirect.com/science/arti...

A 3He-based Holocene glacial chronology from Villarrica volcano, Chile

Understanding alpine glacier extent during past climate variability is instructive for determining the glacier response to future climate change. Vill…

🌋Volcano paper alert! We explore how glacial advances and retreats during the last glacial-interglacial cycle affect volcanoes, using Mocho-Choshuenco🌋 in Chile as a case study. Published in JGR: Solid Earth dx.doi.org/10.1029/2025...

Expansion and Contraction of the Patagonian Ice Sheet and Its Influence on Magma Storage Beneath Mocho‐Choshuenco Volcano, Chile

Intracrustal stress due to ice loading and unloading can influence the depth and longevity of magma storage beneath continental arcs Rapid deglacial unloading can lead to explosive eruption, whic...

#Goldschmidt2025 science making the news! Lots of press coverage on Goldschmidt poster by Moreno-Yaeger et al. Poster Hall 2B - TODAY poster #217: buff.ly/vqRS3ms "Melting glaciers & ice caps could unleash wave of volcanic eruptions" the Guardian (UK): buff.ly/xkdpTj5

I am very happy that our in the Southern Andes is reaching the community! More things are coming soon!

Melting glaciers and ice caps could unleash wave of volcanic eruptions, study says

Long time coming but finally getting our Sierra Nevada work out into the world - discussion still open. More to come. egusphere.copernicus.org/preprints/20...

Deglaciation of the Sierra Nevada (USA) during Heinrich Event 1

Abstract. A polar jet stream (PJS) split by the Laurentide Ice Sheet (LIS) is a well-established feature of Ice-Age atmospheric circulation. California’s central Sierra Nevada Mountains (37–38° N) lie...

New paper by Francisca Núñez Ferreira that among other findings develops a method to use the sediments in esker deposits to inform on the subglacial effective pressure gradient and how it changed in space/time. We find that eskers largely form at the margin. onlinelibrary.wiley.com/doi/10.1002/...

Subglacial hydrology insights from eskers developed atop soft beds of the Laurentide ice sheet

A new method was developed for estimating aspects of the subglacial hydraulic system based on sediments deposited within Eskers. It shows negative basal effective pressure gradients and temporal vari....

Volcano paper alert 🌋🚨! Our new 40Ar/39Ar + 3He ages and magma compositions on Mocho-Choshuenco show an interesting behavior of the volcanic complex before, during, and following the Last Glacial Maximum. See here pubs.geoscienceworld.org/gsa/gsabulle...

While waiting for my flight to Guatemala, I realized that Google Earth updated its images and now shows the lava lake at Villarrica/Rukapillán volcano (Jan. 26th). Beautiful! Looking forward to be at #CitiesonVolcanoes #cov12

A new paper by PhD student Andy Jones. One of those pandemic papers that finally made its way to print. Included zoom calls to teach wet chemistry and multiple hours of FaceTiming during HF and perchloric dissolutions and coordinated lab interchanges. tc.copernicus.org/articles/17/...
