Fitzsimmons, Jessica individual record
Associate Professor

The Fitzsimmons group focuses on inorganic chemical oceanography, particularly trace metal biogeochemistry. We specialize in environmental analytical chemistry measurements, and our research impact centers on 1) micronutrient metal cycling in the open ocean, 2) marine trace metal physicochemical speciation and stable isotope ratios, and 3) heavy metal pollutant cycling in coastal Texas waters.
