Gustavus at GSA

Students and faculty from Geology and Environmental Studies attended the 2012 annual meeting of the Geological Society of America (GSA) in Charlotte, NC. Geology and ES faculty member Julie Bartley gave a talk titled “Microbialites in a high-altitude Andean lake as a natural analogue for Proterozoic stromatolite fabrics”. ES and Chemistry faculty member Jeff Jeremiason presented a poster, “Methylmercury formation in biogeochemical hot spots in an ombotrophic peat bog.” Four Gustavus students also presented posters at GSA – Alison Agather (ES & Chemistry ’13), Rachel Oien (ES & Geology ’13), Emily Seelen (ES & Biology, ’13), and Tara Selly (Geology & Biology ’13). Alison and Emily presented complementary dimensions of the mercury cycle in a peat bog of northern MN; Rachel presented results of work on hydrologic soil properties in Costa Rica, conducted last summer; Tara presented result of experiments that trace the pathways of microbes as they enter the fossil record. Jim Welsh (Geology & ES faculty member) was also able to attend the meeting.
