Mark Abbott Professor, Department of Geology and Environmental Science
Our group combines studies of stratigraphy with geochemical, biogeochemical and stable isotopic analysis to investigate questions regarding climate change and human history. One of the fundamental questions we currently face is how will future climate and environmental change impact society. To answer these questions we need to look further back in time than we are able to do using the instrumental records. Sediments from lakes, bogs and wetlands are found worldwide and provide layered archives that can be analyzed and dated. We combine field and laboratory work to document and date late Quaternary climate changes from lake sediments and other terrestrial deposits, such as glacial features and bogs. The emphasis of my current research program is to identify and recover core samples from lakes that contain climate information recorded at annual resolution. Paleoclimate based temperature and drought reconstruction that document thousands of years of climate and environmental information are helpful for better understand how the earth’s climate system works as well as providing an archive of regional climatic variability.
