Abstract

Understanding and quantifying the carbon cycle is essential to predicting climate change. Dissolved organic matter (DOM) is one of the largest carbon pools globally; furthermore, it controls the fate of trace metals, impacts aquatic productivity by providing nutrients like nitrogen and phosphorous, and affects water color and light absorption. Rivers are the conduits between the land and the ocean, transporting and transforming terrestrially‐derived DOM; estuaries, the brackish mixing zones between rivers and oceans, are hotspots of DOM transformation. In this talk, I discuss the sources and fate of DOM in temperate rivers and estuaries, and the role of DOM in the global carbon cycle. Biographical Information: Laura Logozzo is a fourth‐year PhD candidate at the Yale School of the Environment, working with Prof. Peter Raymond on the biogeochemistry of large river systems. Originally from Brooklyn, NY she attended Fiorello H. LaGuardia High School, where she studied fine art. She received both her Bachelor’s and Master’s degree from the City College of New York. During her Master’s, she worked with Prof. Maria Tzortziou to study the photo and bio‐availability of marshexported dissolved organic matter in Chesapeake Bay, in partnership with the Smithsonian Environmental Research Center
