Have you ever wondered what’s inside a scientific ocean buoy? Take a close look at the critters and seaweed that colonize the bottom of the buoy when we pull our NOAA CO2 buoy out of the water for its yearly servicing.

On Buoy Exploration Day, we’ll provide microscopes, hand lenses, and activities that get you up close and personal with the animals and plants that call San Francisco Bay their home. Scientists and educators will be on hand to identify and catalog the marine organisms, both native and invasive species that live in San Francisco Bay.

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

The buoy will be out of the water and on display from Thursday, August 15 to Thursday, August 22.
