Based on the fossil imprints found in the Historical museum's three staircases, Närhinen endeavours to depict and to re-trace outlines of the coral reefs by means of ink drawings drafted on translucent vellum.
The mapped fossil imprints will be marked with code letters, printed on vinyl and placed directly on the floor cladding. The codes on the limestone slabs refer to the drawn mappings of the Atlas.
The Reef Atlas sets out to map and to imagine the fossil flora of the ancient seabed using the Gotland museum's limestone floor cladding as a starting point.
