Thousands of distinct species live and breathe (or not) in this colorful bacterial terrarium. Look for green cyanobacteria, orange iron oxidizers, and gray cellulose eaters. What you see today will be gone tomorrow in this living artwork in a perpetual state of change.
Bay Lexicon is a visual dictionary made up of illustrated flash cards, exploring the landscape visible from the Bay Observatory’s windows as well as places and phenomena along the shoreline between Fort Point and Hunters Point.
Five clear, rotating disks provide beautiful windows onto the motion of sediments in the Bay. Spin them to compare the behavior of gravel, sand, and fine silt—how the currents carry them and how they settle out of the swirling waters.
