Carbon Dynamics in Northern Marginal Seas
Avhandlingen kommer att försvaras på engelska The marginal seas have, despite their relatively small area, an important role in the global carbon cycle. They are largely influenced by carbon and nutrient fluxes from land and a large part of the biological production occurs in the marginal seas. The...
