Erich Osterberg
Associate Professor of Earth Sciences
My overarching research objective is to understand how and why climate has changed and identify trends and sources of air pollution. My specialty is creating long (50-50,000 years) records of climate change and air pollution by analyzing chemical markers preserved in glacier ice cores. I also study data from weather stations and climate models to determine recent climate trends to differentiate natural cycles from human-caused changes. I am particularly interested in aspects of climate change that impact communities, including sea-level rise from melting glaciers, and the changing number and intensity of storms.

Jacob Chalif
Lab Manager and Grad Student

My primary role involves operating and repairing our continuous melter system and performing geochemical analyses on ice core meltwater samples. Recent projects include a reinterpretation of methanesulfonic acid (MSA) in Arctic ice cores, the development of a Siberian wildfire proxy from the Denali ice core, and a high-resolution chemistry and dust analysis of >1 million year-old Antarctic ice. Outside the ice core world, I use reanalyses and weather station records to examine changing atmospheric circulation patterns over the US. For example, I am using machine learning techniques to examine how a 20th-century cooling trend in the Southeast may have been influenced by slight shifts in jet stream waviness.
