Water quality parameters such as temperature, salinity, dissolved oxygen, clarity, chlorophyll-a, nitrogen and phosphorus are measured at more than 100 stations at least once a month. Trends in water quality parameters are analyzed by state agency and Chesapeake Bay Program partners using a Generalized Additive Model (GAM) statistical approach.</p> <p>More information about the tidal water quality monitoring program and GAM methods can be found here: <a href='https://www.chesapeakebay.net/who/group/integrated-trends-analysis-team' rel='nofollow ugc'>https://www.chesapeakebay.net/who/group/integrated-trends-analysis-team</a></p>
