BN14B:
Bridging Microbial, Stable Isotope, and Micronutrient Approaches to Marine Carbon and Nitrogen Recycling II Posters


Session ID#: 37642

Session Description:
Marine biogeochemistry is critical to the ocean’s ability to regulate atmospheric concentrations of carbon dioxide and other greenhouse gases. Here we examine the nutrient and microbial processes that are important for sustaining the marine carbon (e.g. export production) and nitrogen (e.g. nitrogen fixation, denitrification) cycles, focusing on the use of stable isotope approaches.
