Comparison of Phytoplankton Blooms in San Francisco Bay and Chesapeake Bay

Chesapeake Bay Has High Nutrient Concentration and Large Phytoplankton Blooms

San Francisco Bay Also Has High Nutrient Concentrations But Small Phytoplankton Blooms

One of the Ecosystem Consequences of Large Phytoplankton Blooms Can be a  Decline in Dissolved Oxygen

The figures on this page are modified versions of figure 6 from Cloern, 2001. They depict seasonal changes in selected water-quality constituents of the Chesapeake Bay and northern San Francisco Bay for the year 1997. Data are from the Chesapeake Bay Program Monitoring Station 3.3C and U.S. Geological Survey Station 9 in northern San Francisco Bay. Unit abbreviations: µg/L = micrograms per liter, µM = micromoles, mg/L = milligrams per liter
