Underground Estuary

Underground Estuary

2009 – 2015

The ebb and flow of the tides is a primary factor in changing underground water levels near the Bay. In this exhibit, built over a 25-foot-deep well, the water column moves up and down in synchrony with the tides. A float in the water column drives a chart recorder recording the past month’s groundwater levels.
