Disappearing Rings

Lower these rings into the Bay and see just how far you can see into the water. One of the San Francisco Bay’s defining features, sediment flows from the delta change with the seasons. This exhibit is based on a scientific observational instrument called a “secchi disk,” which scientists use to determine water clarity.
