Our group is involved in a variety of projects using ice cores and other archives to reconstruct past climate and environmental change. Current work includes many aspects of the research in the Center for Oldest Ice Exploration (www.coldex.org), including studies of the oldest ice ever found in Antarctica. We are also involved in studies of many aspects of abrupt climate change and climate reconstruction in both polar regions.
Ongoing work includes greenhouse gases in very old ice, calibrating the sensitivity of water isotope thermometer in ice cores, understanding ice age dynamics in the oldest ice records, changes in methane sources via isotopic measurements, studies of melt and surface mass balance on ice sheets, variations in atmospheric carbon dioxide on many time scales, and characterizing abrupt climate change in ice core data and models. See publications list for recent papers on some of these topics.
