The role of continental shelves in nitrogen and carbon cycling: Northwestern North Atlantic case study
Continental shelves play a key role in the cycling of nitrogen and carbon. Here the physical transport and biogeochemical transformation processes affecting the fluxes into and out of continental shelf systems are reviewed, and their role in the global cycling of both elements is discussed.
