Gabbie Ledesma (’20), a geology major, has been awarded an Iowa Space Grant Consortium undergraduate research fellowship for 2019-2020. This will provide her will a stipend to do independent research with Dr. Elizabeth Swanner. She will continue her investigations of Manganese enrichments in lake sediments in order to better understand Manganese enrichments in the former … Continue reading Gabbie Ledesma awarded an Iowa Space Grant Undergraduate Research Fellowship
Nick Lambrecht successfully defended his PhD! He is the first graduate student to graduate from the Geochemistry & Geobiology laboratory. His research investigated two meromictic ferruginous lakes in the Midwest, U.S.A. Specifically, he documented their potential as biogeochemical analogues to Precambrian ferruginous oceans, and the microbial iron and methane cycles within them. Nick’s PhD is … Continue reading Nick Lambrecht defends his dissertation

Everyone knows Mars is called the Red Planet. But maybe its other nickname should be the Cardinal and Gold Planet. After all, with important research being conducted by Iowa State students like Gabrielle Ledesma (’20 geology) and team, conditions on Mars that led to its red surface are becoming clearer by the day.
The first student paper in our research group has been published! Check out Lambrecht et al., 2018 in the Journal of Geophysical Research: Biogeosciences. (https://doi.org/10.1029/2018JG004587) This study documents two midwestern lakes as ferruginous and meromictic, properties that make them useful analogs to past ferruginous oceans.
New work published in the journal Scientific Reports by Dr. Elizabeth Swanner and colleagues simulates the iron cycle in an ancient ocean – with surprising results. Read the story here, and link to the publication here.
