Dr. Katrina Moser is a Professor in the Department of Geography at Western University. Her research is on water quality and quantity issues, and specifically how humans are impacting these important resources. Key questions that she is interested in are: (1) how will future climate warming impact water resources? (2) how has anthropogenic pollution affected “pristine” alpine and arctic lakes? (3) can climate and pollution synergistically impact water resources? In order to look at these questions she uses paleolimnological techniques, which provides her with long term (100s to 1000s of years) records of changes in water quality and quantity. Paleolimnology uses fossils and geochemical signals preserved in lake and river sediments (mud) to infer environmental change.
