Abstract: What happens under volcanoes in the months leading up to eruption? How does a magmatic system prepare for an eruption? And why are some eruptions more explosive than others? Crystal clocks are providing some answers to these questions. Chemical zonation preserved inside crystals and their inclusions are some of the...
Abstract: Wildfires and other types of biomass burning are a seasonal phenomenon in different land ecosystems around the world. These fires are estimated to consume biomass containing a total of 2-5 petagrams of carbon globally every year, generating heat energy and emitting smoke plumes that comprise different species of aerosols and trace...
Talk Title: From Microbial to Global: What Mercury Stable Isotopes Can Tell us about Mercury Bioaccumulation
Abstract: Mercury (Hg) stable isotopes have become a standard approach to study Hg sources and processes in the environment. Despite the power of these tools, applying Hg isotopes to understand source to receptor relationships can be difficult due to the myriad of...
Department Tutorials provide an opportunity for EPS concentrators and prospective students alike to meet with EPS faculty in an informal setting. In addition to learning about the variety of research available within EPS, the tutorials are also a great way to meet other students interested in earth and planetary sciences.
Our April presenter is Professor Marianna Linz, whose research focuses on the distribution of trace gases in the stratosphere, temperature extremes in the troposphere,...
Talk Title: Promises and Pitfalls of Paleoredox Proxies in Carbonate Rocks
Abstract: The redox state of the oceans strongly influences organic carbon burial, habitability for marine biota, and biogeochemical cycling of nutrients and critical redox-sensitive elements. There are various methods for reconstructing oxygenation and deoxygenation through Earth history: Of these,...
