Sarah Crump Graduate Fellowship

With the help of Sarah, her family, and friends, INSTAAR has established a fellowship in her name. Please help us raise an endowment sufficient to support a full-year Graduate Research Fellowship, providing salary and tuition for one INSTAAR grad student each year. The fellowship will give a boost to their study of Earth or environmental science in Arctic or alpine regions and also be a lever for equity and underserved communities.

Ice cores record long-ago seasons in Antarctica (AGU Eos)

Researchers led by INSTAAR Tyler Jones used ice core data to reconstruct seasonal temperatures throughout the Holocene. The results link especially hot summers with patterns in Earth’s orbit. The results are the first seasonal temperature record stretching back 11,000 years. Read more

Why rain on snow in the California mountains worries scientists (The Conversation)

Another round of powerful atmospheric rivers is hitting California, following storms in January and February 2023 that dumped record amounts of snow. This time, the storms are warmer, and are triggering flood warnings as they bring rain higher into the mountains on top of the snowpack. Keith Musselman explains the complex risks rain on snow creates and how they might change in a warming climate. Read more

Towering over nine feet tall and weighing over 1,500 pounds, the now-extinct aepyornis lived more than 1,200 years ago and was Madagascar’s largest land animal. Scientists at the University of Colorado Boulder and Curtin University in Australia recently discovered a new lineage of the birds using eggshell remnants, as well as isotope geochemistry and protein extraction. The findings were published in Nature Communications. Read more
