This report, a product of the Puget Sound Ecosystem Monitoring Program’s Marine Waters Work Group, is the twelfth annual report on marine water conditions in Puget Sound. Since 2011, Puget Sound Marine Waters has compiled data from numerous environmental monitoring programs to report on the state of Puget Sound’s marine waters during the previous year.

The report combines a wealth of data from comprehensive monitoring programs and provides a concise summary of what was happening in Puget Sound’s marine waters during 2022. It covers areas such as climate and weather, river inputs, seawater temperature, salinity, nutrients, dissolved oxygen, ocean acidification, phytoplankton, biotoxins, bacteria and pathogens, shellfish resources, and more.
