Building on material from the project Mississippi. An Anthropocene River of 2018–2019, researchers Jason Ludwig and Tim Schütz address the challenges of archiving the Anthropocene in its multitude of local contexts. The research acknowledges that gathering diverse data on the Anthropocene(s) is necessary to avoid producing universalizing—and thereby less applicable—knowledge. Providing insight into the use of online archives and civic data infrastructures, this case study presents an attempt at “archival bridging” between different localities experiencing similar environmental problems.
