Meet BOB and MARI, the newest buoys in the San Francisco Bay

As the water chemistry changes off the coast of California due to increased levels of CO2 in the atmosphere, scientists are collaborating to detect these changes in near real time. CeNCOOS is working with researchers from San Francisco State University, University of California at Davis, San Francisco Estuarine Institute, and other federal and local partners to deploy two new buoys in San Francisco Bay, the Bay Ocean Buoy (BOB) and the Marine Acidification Research Inquiry (MARI).


These buoy are equipped with sensors for measuring carbon dioxide in the atmosphere and the water, as well as dissolved oxygen, pH, chlorophyll-a (a measure of the amount of microscopic phytoplankton in the water) and other oceanographic measurements. The sensors will make measurements at the surface and a depth where open-ocean waters enter the Bay. Soon, the information produced from these instruments will be made publicly available on through the CeNCOOS Data Portal.

This research addressing a particularly challenging but increasingly important phenomena to understand, ocean acidification. These instruments will greatly contribute to regional and larger scale efforts to better manage our marine environment and the many resources and services it provides.
