ESS Colloquium: Lucien Nana Yobo (Texas A&M University, Ocean Discovery Lecture Series) "Earth's Fiery Past: Large Igneous Provinces, Anomalous CO2, and their Environmental Impacts""

Abstract: Large igneous provinces (LIPs) are among the most influential drivers of global Earth system changes. These massive volcanic events are linked to extreme climate and ocean conditions, increasing global temperatures, ocean acidification, and widespread marine anoxia. ​​Their emplacement and CO2 release frequently align with some of Earth’s most rapid environmental shifts, including four of the five major mass extinctions—most notably the End-Permian extinction, the largest of the Big Five—highlighting their critical role in past Earth systems transitions. However, studying LIPs—particularly submarine ones—remains challenging, as much of their eruptive material is buried beneath the ocean or has been subducted over time. Consequently, much of our understanding of these events has often relied on sedimentary geochemical proxies. These proxies, including osmium isotopes, mercury concentrations, and carbonate dissolution patterns, have become essential tools for reconstructing LIP emplacement and assessi… Event interval: Single day event.

ESS PetroLunch: Dr. Nadja Drabon (Harvard University; joining via Zoom) "Hadean Zircon from South Africa: Insights into the Habitability of the early Earth"

If you would like to receive updates about Petrolunch and are not currently on our email list, please sign up here:  http://mailman11.u.washington.edu/mailman/listinfo/petrolunch. We recommend signing up for the listserv in order to receive direct updates and communications in the event of last-minute cancellations. Petrolunch will be taking place on Fridays at 12:30 pm in the QRC (JHN 377) and are simultaneously broadcast online (https://washington.zoom.us/j/98791970331  Meeting ID: 987 9197 0331).  Abstract: The surface environment of the early Earth remains obscure due to the dearth of a rock record for Earth’s first ~500 million years. Although life likely emerged then, key questions remain about how crust formed, how widespread liquid water was, and what habitats existed. The surviving archive from that time is carried by the mineral zircon, most famously from the Jack Hills in Western Australia. In this talk, I will extend that record by adding a second locality in South Africa with detrital zircons… Event interval: Single day event. Campus location: Johnson Hall (JHN).

ESS Colloquium: Eric Steig (UW ESS & PCC) "Water isotopes are magical: fundamental things isotope records from ice cores tell us about climate variability and ice sheet change across timescales from decades to millennia"

Abstract: The discovery that oxygen and hydrogen isotopes in snowfall provide a window into the past through ice cores is more than six decades old.  Yet the “old” technology of water isotopes continues to be a cornerstone of our understanding of both past and current climate in the polar regions.  Recent advances include measurement methods that improve both resolution and precision; a revolution in dating of ice cores, allowing us to compare them with one another with high confidence; and the development of ways to use water-isotope data to constrain and validate climate model simulations. Three examples – on very different timescales – illustrate the continued magic of ice-core isotope records. First, we have long wanted to know how big the Antarctic and Greenland ice sheets may have been during the last glacial maximum, how much they thinned during the Holocene, and how small they were during previous interglacial periods, when sea level was much higher than present. We now know the answer to all these… Event interval: Single day event. Campus location: Johnson Hall (JHN). Campus room: JHN 075. Accessibility Contact: Disability Services Office, dso@uw.edu.

Despite the importance of native gold as an ore mineral, the use of its composition for these purposes remains underutilized. This is significant, as native gold is unequivocally associated to economic mineralization, thus providing a direct way to investigate… Event interval: Single day event.

ESS Colloquium: Hannah Shamloo (Central Washington University) "Timing is Everything:
Pre-eruptive magmatic processes and timescales for 
Mount Baker volcanism, Cascades USA"

Keywords: igneous petrology, volcanology, geochemistry Abstract: Volcanic eruptions are some of the Earth’s most devastating hazards. Specifically, the timing between volcanic unrest and an eruption is difficult to forecast, requiring a thorough understanding of the magmatic plumbing system beneath a volcano. A magma’s crystal cargo directly records the thermophysical storage conditions of the magma prior to eruption. Specifically, chemical zoning that forms during crystal growth with changing magmatic conditions can record a magma’s history, akin to rings of a tree. In the last two decades, improvements in experimental petrology and analytical instruments have led to the technique of diffusion chronometry becoming widespread. In this talk, I will demonstrate the power of combining petrologic methods (mineral geochemistry, thermobarometry, textural analysis) with diffusion chronometry for the reconstruction of the pre-eruptive histories of magmas. Specifically, Kulshan (Mount Baker) in Washington state is an… Event interval: Single day event. Campus location: Johnson Hall (JHN). Campus room: JHN 075.
