Hafrún is the name of the most ancient ocean quahog ever known. When discovered and dredged, it was 507 years old. Like the rings of a tree trunk, quahog shells serve as archives preserving centuries of climate changes. The video, named after the mollusk, portrays the process of data collection from the shells of Atlantic clams. Like scientists in the laboratory, we ask ourselves: what can we learn about climate change from more-than-human forms of life?
