Aeolian Landscape
Aeolian Landscape presents a swirling storm of sand inside a large chamber covered by a plexiglass top. A knob on the top of the exhibit rotates a sturdy fan set in the base of the chamber.
Where: Crossroads: Getting Started
Bay Sediment Cores
Sediment cores offer clues to the many histories of the Bay.
Where: This exhibit is not currently on view.
Bay Windows
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.
Where: Koret Foundation Bay Walk
Black Sand
At this simple but ever-popular exhibit, black sand from nearby beaches make spiky patterns that reveal the invisible magnetic field between the poles of two giant magnets.
Where: Ray and Dagmar Dolby Atrium
Braided Stream
This artwork features air bubbling up through a fine powder constrained between two glass plates tilted at a 45 degree angle. The tilting creates a continually changing landscape evocative of aerial photographs of river drainage networks on Earth and on Mars.
Where: Crossroads: Getting Started
Color of Water
Water reflects the blue of the sky, but if you look down into it, its color is based mostly on the green of marine algae—phytoplankton—and the brown of suspended silt. This array of color chips lets viewers determine what’s influencing the color of water today.
Where: Gallery 5: Outdoor Exhibits
Confused Sea
Air blowing over the surface of water inside a large Plexiglas hemisphere mimics the action of the wind over the ocean by generating waves. The waves slowly change and build until the entire volume of water is circulating as one wave. Viewers can adjust the speed of the air blower and influence the building of the waves.
Where: Crossroads: Getting Started
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.
Where: Gallery 5: Outdoor Exhibits
Fluttering
A constant stream of air forces a lightweight piece of free-flowing fabric up into the air. The normally invisible air current is suddenly transformed into a colorful visualization of the complexity of the air stream.
Where: Crossroads: Getting Started
Fluvial Storm
Swirling water sculpts elaborate patterns of underwater dunes.
Where: This exhibit is not currently on view.
Fog Bridge #72494
In a city notorious for fog, this immense artwork by Fujiko Nakaya intermittently shrouds a pedestrian bridge spanning Piers 15 and 17 with clouds of mist, enveloping all in its gauzy embrace.
Where: Plaza
Geysers
The timing of the eruptions of these geysers depends on water temperature and pressure.
Where: Gallery 4: Living Systems
Glass Settling Plate
Almost any hard object submerged in San Francisco Bay—from pier pilings to the sides of sailboats—quickly becomes a habitat for an ever-changing community of living things. Here you can use a joystick-driven microscope to take a tour of the wonderland of living creatures that have settled on a glass plate that has spent some time submerged in the Bay.
Where: Gallery 4: Living Systems
Icy Bodies
Like comets, these chunks of dry ice slowly disintegrate as they move, leaving a visible trail of condensed water vapor.
Where: Crossroads: Getting Started
Library of Earth Anatomy
Library of Earth Anatomy, a collection of remarkable geological artifacts that invite and inspire us to see rocks in new ways. The Library employs unconventional classification methods to dissolve the usual boundaries between nature and culture, as well as between animal, vegetable, and mineral.

Life on the Rocks
All these organisms are adapted to life in California's rocky tidal zone.

Living Systems Explainer Station
Explainers do biology and botany demonstrations.
Where: Gallery 4: Living Systems
Mapping Migrations
This interactive data visualization reveals the migration tracks of sharks, whales, sea turtles, tuna, and other marine creatures, and lets visitors explore differences in timing, geographic location, and male versus female migration routes.
Where: Gallery 4: Living Systems
Native Oyster Colony
Get a closer look at live, Olympia oysters, native to San Francisco.

Pier Piling Pivot
This exhibit uses a geared motor to swing a specially designed piling out of the water so that visitors can examine it in detail. An accompanying legend identifies the intertidal zones on the piling and the species of plant and animal life occupying this unique shoreline environment.
Where: Gallery 5: Outdoor Exhibits
Plankton Populations
Different types of phytoplankton multiply or die off in response to changing ocean conditions.
Where: Gallery 4: Living Systems
Plankton Rainbow
Plankton can distinguish between different colors of light.
Where: Gallery 4: Living Systems
Research Buoy
This NOAA buoy gathers data on CO2 levels, which are increasing in our oceans and affecting marine life.
Where: Gallery 5: Outdoor Exhibits
Rift Zone
Rift Zone uses air bubbling up through fine sand to suggest a small-scale geothermal landscape. By turning a knob, viewers can change the pressure of the air rising up through the sand and alter the shapes and patterns of the landscape.
Where: Crossroads: Getting Started
Saltscapes
The South San Francisco Bay salt evaporation ponds take on a variety of colors due to halophilic organisms that adapt to various salinities. Photographer Cris Benton captures this vibrant landscape in a series of aerial photos taken from homemade kite-cameras flown over the ponds.
Where: Gallery 4: Living Systems
Seismograph
This seismograph is an earthquake detector that records the up-and-down motion of the ground—whether made by tectonic activity or by you.
Settling Column
Sand falling through water creates turbulence and complex patterns.
Sky Theater
Sky Theater is a rear-projected enclosure designed to reveal and celebrate unseen patterns of the daytime sky.
Where: Fisher Bay Observatory Gallery 6: Observing Landscapes
The Atmosphere: A Guide
This poster-essay depicts human influences on the sky and their accumulated traces, whether chemical, narrative, spatial, or political. Visually referencing the Cloud Code Chart, the guide explores ways that humans literally and figuratively occupy the present, past, and future atmosphere, from sea level to the exosphere.
Where: Fisher Bay Observatory Gallery 6: Observing Landscapes
Tidal Flow
Floating orange arrows turn a series of leftover pilings into a visual representation of water movement into and out of the Bay. As tides rise and fall, the arrows travel up and down the pilings, swiveling to point the direction of the water flow.
Where: This exhibit is not currently on view.
Tidal Memory
Twenty-four columns record twenty-four hours of tide water levels.
Where: Gallery 4: Living Systems
Tornado
Fans simulate the swirling airflow in a thunderstorm and fog machines make the pattern visible, creating a miniature tornado that you can disturb with the wave of a hand.
Where: Gallery 4: Living Systems
Watch Water Freeze
Ordinarily, water freezes too slowly to be appreciated. Here, polarized light and an ultra cold slab let you watch water crystalize rapidly in real time. The colorful mosaic of ice that forms is different every time.
Water Waves—Time Horizon
Water Waves is a multi-monitor video installation and time-horizon study of the power and beauty of ocean waves.
Wave Organ
Sound at this wave-activated acoustic sculpture is created by the impact of waves against the pipe ends and the subsequent movement of the water in and out of the pipes. The sound heard at the site is subtle, requiring visitors to become sensitized to its music, and at the same time to the music of the environment.
