EnviroThursday - “Poetry in the Age of Ecocatastrope: Readings from Meltwater“

Speaker:  Claire Wahmanholm, author of Meltwater

Claire Wahmanholm will read from her latest collection, Meltwater (Milkweed Editions, 2023) and discuss what poetry can offer us during the age of climate collapse, ecocide, species loss, and extractive capitalism. The talk will end with a Q&A and selection of writing prompts.

Claire received her BA from UW-Madison, her MFA from the Johns Hopkins University, and her PhD from the University of Utah. Her debut full-length collection, Wilder (Milkweed Editions), won the 2018 Lindquist & Vennum Prize for Poetry, the Society of Midland Authors Award for Poetry, and was a finalist for the 2019 Minnesota Book Award. Her second collection, Redmouth, was published with Tinderbox Editions in 2019. Her third collection, Meltwater (Milkweed Editions 2023) is a finalist for the 2024 Minnesota Book Awards and the 2024 Kingsley Tufts Poetry Award. She was a 2020-2021 McKnight Writing Fellow, and her poem, “Glacier,” won the 2022 Montreal International Poetry Prize. Her work has most recently appeared in Sierra, The Hopkins Review, The Anarchist Review of Books, TriQuarterly, Ninth Letter, and Blackbird, and has been featured by the Academy of American Poets.

This event is co-sponsored by the Environmental Studies, English and Geology Departments.

Department of Geology Seminar: A Reappraisal of Olivine Growth Rates

Benoit Welsch, Macalester Visiting Scholar, will speak about Olivine.

"Olivine is a ubiquitous rock-forming mineral that can record a wide variety of dynamic processes during its lifetime. However, the details of its crystallization from a silicate melt are complex, specifically regarding crystal habits and growth kinetics.

"Olivine can develop a wide variety of crystal shapes depending on its crystallization environment, at growth rates spanning 10 orders of magnitude, from 10-16 m/s to 10-6 m/s and more. In this talk, I will present results of dynamic crystallization experiments using a heating stage microscope to investigate in situ the early stages of olivine crystal growth inside a plagioclase-hosted melt inclusion. I will also touch upon how large discrepancies between datasets can arise from a variety of methodological inconsistencies, limitations, and outright errors, as well as broad uncertainties regarding the timing and manner of crystal growth."
