The study, “Stable Ca and Sr isotopes support volcanically triggered biocalcification crisis during Oceanic Anoxic Event 1a” was published in the journal Geology on Dec. 16.
Jiuyuan Wang, is Ph.D. candidate and the first author of the study. Professors Andrew Jacobson, Bradley Sageman and Matthew Hurtgen of the Department of Earth and Planetary sciences coauthored the paper.
The researchers discuss their study in the story “Volcanic eruptions directly triggered ocean acidification during Early Cretaceous: First study to use stable calcium and strontium isotopes to examine oceanic anoxic event,” in Northwestern Now.
