Short summary
Organic molecules dissolved in the waters of coastal seas (DOM) are a potentially important vector for carbon transport and storage in the open ocean. DOM carbon and nitrogen concentrations from two consecutive summers in the North Sea show a strong pattern of concentrations decreasing away from land. We also observe significant differences between the years in both the DOM concentration and C : N ratios, suggesting that carbon export from shelf seas might be mediated by organic matter cycling.
