Mare Liberum is a collective of visual artists, designers, and writers who formed around a shared engagement with New York’s waterways in 2007. ML’s work bridges dialogues in art, activism, and science, by remapping landscapes, reclaiming local ecologies, and observing and recording the overlaps of nature, industry, and the polis. ML’s projects connect divergent constituencies with shared environmental concerns, create waterfront narratives ranging from the industrial to the personal, and catalyze the creation of engaged publics. The collective is currently led by Jean Barberis, Ben Cohen, Dylan Gauthier, Sunita Prasad, Kendra Sullivan, and Stephan von Muehlen. More information at: http://www.thefreeseas.org.
