Bay Day

Our annual celebration of the San Francisco Bay and ocean science returns! We’ll be pulling our NOAA data-collection buoy out of the water for its yearly servicing, and have scientists on deck to showcase the fascinating organisms that grow on the buoy and elsewhere in the Bay. Immerse yourself in ocean science and ecology, and join us for a variety of activities for marine enthusiasts of all ages.

About the CO² Buoy

On loan to us from the National Oceanic and Atmospheric Administration (NOAA), the CO² buoy has been anchored between Piers 15 and 17 since April 2013, collecting data on water temperature, salinity, and CO² levels in the atmosphere and the Bay. Every year, we pull it out of the water to calibrate and replace the sensors and to clean off corrosion and marine organisms.
