No 58. Tidal Timespace and the Palimpsests of Bahía Adair, by Heather Green, Gulf of California, US, (2019).

From the project website.

“Description of the audio/visual work:

This mixed-media installation will consist of a series of 9 plaster casts that float on steel pedestals and capture some of the patterns and scripts made from the diverse mudflat textures left at low tide. A sequence of oil paintings hang on the wall, depicting an aerial view of a tidal sequence in the same scale and sizes as the casts. These portray the tide slowly coming back in and covering the mudflats. The sequence starts with intricate moiré patterns in shallow water and slowly gets greener, bluer, ending with a panel that shows the opaque surface of deep water.”
