My interests lie in discovering how climate change will affect geochemical and nutrient cycling. This question is important because these basic building blocks help control the productivity of ecosystems. My research in the Raymond Lab specifically looks at inorganic carbon in glacially fed estuaries and tries to determine net heterotrophy in these changing environment. These systems are important ecologically and are the key outlets to ice fields undergoing rapid transformation from climate change. To help answer my research question, I use carbon isotope analysis, gas chromatography, and a suite of water chemistry parameters. In the summer of 2014, I collaborated and collected data with researchers from Skidaway Institute of Oceanography, Woods Hole Oceanic Institute, and University of Alaska Southeast. My study sites are in southeastern Alaska, Berner’s Bay and St. James Bay.
