Role Of Phytoplankton In Mercury Cycling In The San Francisco Bay Estuary, Allison C. Luengen, A. Russell Flegal
Environmental Science
To study the role of phytoplankton in mercury cycling, we measured methylmercury (MeHg) and total mercury (HgT) in surface waters during the spring 2003 phytoplankton bloom in San Francisco Bay. Conditions that described the peak of the bloom, the amount of sorbent, and decay of the bloom were summarized by principal component analysis (PCA). Multivariate analyses conducted with the PCA factors demonstrated that the bloom accounted for a significant (p = 0.03) decrease in dissolved (-1 and was unaffected when chlorophyll a concentrations nearly tripled, indicating that bloom dilution could occur as a result of a limited …
