We know that Vikings settled and lived in Greenland sometime during the Middle Ages, but many questions remain regarding what climate was like and how the Vikings actually lived during this period. By coring lakes near the settlements and analyzing biomarkers within the sediments, this project will attempt to reconstruct both the paleoclimate and paleo-environment in this region. Knowing what the climate was, and how it changed through time, will give us clues about how the Vikings were able to farm and graze livestock, as well as what changed that led to these settlements demise.
