Four Decades of Water Quality Research in San Francisco Bay

Infographic highlighting trends and discoveries from the first four decades of water quality research in San Francisco Bay.

Detailed Description

The continuous study of water quality in San Francisco Bay since 1969 provides a rich dataset to explore how this estuarine system has changed over time. This 2009 presentation depicts: how the rivers and ocean influence the estuary; phytoplankton taxonomy changes due to a large climatic shift;  decreasing nutrient concentrations; how phytoplankton blooms have changed in different parts of the system; and improvements in bottom water oxygen levels since the 1970s.
