Tessa HillTessa Hill | Unfold Podcast, Episode 6: Oceans Under a Changing Climate

From UC Davis: Oceans have always done us a favor by absorbing carbon dioxide from the atmosphere. But, increasingly, greenhouse gases are warming the ocean and changing its chemistry. All of this is putting marine species and ecosystems at risk, threatening food security and the livelihoods of people along its shores. In this episode of Unfold, we take a deep dive into the ocean to examine the effects of climate change. Dr. Tessa Hill is featured in this episode.

Cathy BusbyCathy Busby | 2020 MGPV Distinguished Geologic Career Award

Cathy Busby, Professor Emerita, has been awarded the 2020 Distinguished Geological Career Award from the MGPV (Mineralogy, Geochemistry, Petrology, and Volcanology) Division of the Geological Society of America. This award goes to an individual who, throughout his/her career, has made distinguished contributions in one or more of the following fields of research: mineralogy, geochemistry, petrology, volcanology, with emphasis on multidisciplinary, field-based contributions. The MGPV Distinguished Geological Career Award emphasizes a geologic and multidisciplinary approach.

Isabel MontanezIsabel Montañez | 2021 Francis J. Pettijohn Medal for Sedimentology

Dr. Isabel Montañez will be awarded the 2021 Francis J. Pettijohn Medal for Sedimentology from the Society for Sedimentary Geology (SEPM)! This award is given in recognition of Excellence in Sedimentology. Nominees for the medal are persons who have a significant record of outstanding contributions in sedimentary geology, including all aspects of sedimentology and stratigraphy. This also follows two other recent, prestigious awards to Isabel: The GSA Sloss Award in 2018, and the Jean Baptiste Lamarck Medal from the European Geosciences Union (EGU) in 2019.

Tessa HillTessa Hill | For Red Abalone, Resisting Ocean Acidification Starts With Mom

From UC Davis: Study Identifies Traits of Climate-Resilient Red Abalone, With Implications for Farmed Abalone. Red abalone mothers from California’s North Coast give their offspring an energy boost when they’re born that helps them better withstand ocean acidification compared to their captive, farmed counterparts, according to a study from the Bodega Marine Laboratory at the University of California, Davis. Tessa Hill is a co-author on the study.

Jeff MountJeff Mount | How California Became Ground Zero for Climate Disasters

From the NYTimes: The engineering and land management that enabled the state’s tremendous growth have left it more vulnerable to climate shocks — and those shocks are getting worse. The state’s size and geographic diversity expose it to an unusually wide range of extreme climate events. And its large population means that when disasters do strike, they are very likely to affect large numbers of people.

Curtis WilliamsQing-zhu YinCurtis Williams and Qing-zhu Yin  | Meteorites Show Transport of Material in Early Solar System

From UC Davis: New studies of a rare type of meteorite show that material from close to the sun reached the outer solar system even as the planet Jupiter cleared a gap in the disk of dust and gas from which the planets formed. The results, published this week in Proceedings of the National Academy of Sciences, add to an emerging understanding of how our solar system formed and how planets form around other stars. The consensus theory on how planets form is that they accrete from a disk of dust and gas that rotates around a new-formed star.

Evidence for the composition of this protoplanetary disk in our own solar system comes from chondrites, a type of meteorite made up of smaller particles, or chondrules, that collected together like a cosmic dust bunny. “If we understand transport, we can understand the properties of the disk and infer how the planets were built,” said Qing-zhu Yin, professor of earth and planetary sciences at the University of California, Davis, and co-author on the paper. Yin, UC Davis research scientist Curtis Williams, and their collaborators carried out a detailed study of isotopes from 30 meteorites. They confirmed that they fell into two distinct groups: the noncarbonaceous chondrites as well as other, more common types of meteorite; and the carbonaceous meteorites.
