Brita Lorentzen

UGA Arch
Assistant Professor

I use dendrochronology, wood anatomy, tree-ring stable isotopes, and wider archaeobotanical methods to investigate human-environment interactions and their long-term impact legacies during the Anthropocene. My recent studies focus on the challenge to articulate a high-resolution chronology appropriate and comparable with the lived histories of the Indigenous village settlements in Northeast North America. I study how humans have used timber resources and shaped forest ecosystems over time, with a particular interest in high precision dating to better understand environmental factors and socioeconomic networks in southeastern Europe

Articles Featuring Brita Lorentzen

In the 1960s, the excavation of an ancient Greek merchant ship off the northern coast of Cyprus revealed an extraordinary time capsule from the early Hellenistic period. Accurately dating the Kyrenia shipwreck, however, had been a significant challenge due to…
