Anne-Martine (Marti) Doucet is a Research Technician at the University of British Columbia currently working with the CarbMin laboratory supervised by Dr. Greg Dipple and Dr. Uli Mayer. Her research focuses on measuring and monitoring CO2 exchange at the sediment-atmosphere interface in natural and engineered environments that enable carbon mineralization reactions (where CO2 from the atmosphere or water reacts with cations (Ca, Mg) and precipitate a carbon mineral). She completed her Bachelor degree at the University of Ottawa in Environmental Sciences with a focus in Environmental Geochemistry and recently completed a Masters degree here at UBC in Geological Sciences supervised by Dr. Uli Mayer. In her spare time, you can catch Marti biking (on roads and mountains) and playing disc golf.

Three EOAS undergraduate students attended the Joint Annual Meeting of the Geological Association of Canada, Mineralogical Association of Canada, and Society for Geology Applied to Mineral Deposits (GAC-MAC-SGA) in Sudbury, Ontario in the past week to present original research that they conducted with graduate students and faculty at UBC.

Helen Kopystecki's presentation, entitled, "Revisiting the paleoelevation history of the central Altiplano using stable isotopes in hydrated volcanic glass from the Corque Syncline, western Bolivia", builds on her 1.5-month field work in Bolivia in 2022. Her results call into question a long-standing paradigm that the Andes were rapidly uplifted in the late Miocene. They hypothesized that since major elevation changes are recorded by all paleoelevation proxies in the Corque stratigraphic section, carbonate- and volcanic glass-based proxies should yield the same reconstructed paleoelevations. However, their data indicated that volcanic glass and carbonate may record distinct environmental signals: reconstructed paleowater δD values from volcanic glass suggests that the central Altiplano has been at near modern elevations since at least 11 Ma, contrasting with δ¹⁸O values from carbonate rapidly decrease between 10 and 6 Ma. They suggested that more work is needed to understand influences on the isotopic composition of these two common paleoelevation proxies.

Julia Leandro's presentation entitled, "Reconstructing Maastrichtian–modern sediment delivery to the forearc Georgia Basin using detrital zircon U-Pb geochronology" includes the results of detrital zircon geochronology from the Huntingdon Formation in southern BC. Her results provide the first absolute ages for the Huntingdon Formation near urban Vancouver. Her data showed that Huntingdon Formation is Eocene in age and that major contraction of the eastern catchment of the Georgia Basin happened between the Late Cretaceous and the Eocene. Because of Huntingdon Formation’s lack of Proterozoic grains, neither the Maastrichtian Nanaimo Group nor the source of its Proterozoic grains are a sediment source for the forearc region into the Eocene. Their data also showed that the catchment of the forearc region in the Eocene did not reach past the Coast Plutonic Belt and that the catchment’s current trans-cordilleran extent was not reached until the Holocene.

Muhammad Rafeeza presented new detrital zircon geochronology from Bolivia in his poster entitled, "Provenance of Late Cretaceous to early Neogene strata in the Camargo Syncline and implications for basin geometry in southern Bolivia," which also builds on field work in South America. His results provide confirmatory data for the existing geodynamic model while at the same time calling into question source-to-sink (fluvial) relationships between the magmatic arc and the retroarc foreland. Their detrital zircon data is consistent with coeval recycling and mixing of Eastern Cordilleran detritus and onset of Eastern Cordilleran exhumation by the Oligocene-early Miocene. Their data also provides rough timing consistent with other published studies regarding the onset of the Eastern Cordilleran orogeny and is consistent with a foreland basin extending from the Western Cordillera to the interior in the Late Cretaceous to Paleocene.

Within the past few years, Vancouverites have experienced more intense and frequent extreme weather events. Two summers ago, BC was hit with a catastrophic heat wave, which was followed by a series of atmospheric rivers in the Fall of 2021. Many of us remember the scorching heat and the highway closures due to flooding, but how do these weather extremes develop? 

During an interview for CBC's Planet Wonder series, Dept. of Earth Oceans and Atmospheric Sciences professor, Dr. Rachel White recently explained how such weather events are formed and carried by the atmosphere’s jet streams. While standing in the Pitt River, Dr. White used her surroundings to describe the jet stream, comparing storm systems to the eddies created in the meandering river. The series host and CBC meteorologist, Johanna Wagstaffe, used further visual aids including a turntable and water bath to explain how temperature gradients between the poles and the equator on our spinning planet act to create the jet stream. By the end of the 25 minute episode, viewers are walked through 1. How the jet stream is formed, 2. How it creates extreme weather events felt on Earth’s surface, and 3. How climate change is impacting the jet stream. To watch Rachel White’s feature head to Season 1, Episode 7 ‘What’s going on up there to make weather down here so extreme’.

We are excited to announce that our newest video series, Climate Myth Busters, is live now! This series showcases brief, 1-minute videos featuring EOAS graduate students and faculty debunking widespread misconceptions about Earth's climate. We are excited to share this content with the public, sparking meaningful conversations around climate science. Watch the videos on Youtube or on our Climate Crisis page.

Dr. Catherine Johnson, Professor in the Department of Earth, Ocean and Atmospheric Sciences, has been elected to the National Academy of Sciences. Dr, Johnson is among 120 new members and 23 international members elected this week, and she joins five other UBC Science researchers as a member of the Academy. The National Academy of Sciences is a private, non-profit institution that was established under a congressional charter signed by President Abraham Lincoln in 1863. It recognizes achievement in science by election to membership, and—with the National Academy of Engineering and the National Academy of Medicine—provides science, engineering, and health policy advice to the federal government and other organizations. Members are elected to the NAS in recognition of their distinguished and continuing achievements in original research. Membership is a widely accepted mark of excellence in science and is considered one of the highest honors that a scientist can receive.

Dr. Johnson uses observatory and satellite data to probe the interior structure and history of terrestrial planets, moons and small bodies in our solar system. She has been a co-investigator on several NASA planetary missions. Recent work by Dr. Johnson has delved into the geological characteristics of Mars and Earth’s moon. The research indicates Mars had a global magnetic field much earlier—and much later—in the planet's history than scientists have previously known. Her work with researchers at the Smithsonian using Apollo mission seismic data shows that some shallow moonquakes can be linked to young faults—evidence that the moon, like Earth, is tectonically active.
