Emily M. Bristol, PhD
I am a biogeochemist studying organic matter in Arctic coastal waters. I investigate how rivers, coastal erosion, and groundwater impact carbon and nitrogen cycling in the Alaska Beaufort Sea.
I am broadly interested in biogeochemical cycling along terrestrial-aquatic-marine continuums. My current research examines the sources and fate of terrestrial organic matter in the Arctic Ocean. I use various geochemical analyses such as isotopes, high-resolution mass spectrometry, and biomarkers to characterize organic matter in soils, freshwaters, and marine sediments. These tools provide information about the sources and biodegradability of organic matter, helping us understand how terrestrial inputs impact greenhouse gas emissions and marine productivity.
