The sensitivity of marine N2 fixation to dissolved inorganic nitrogen

The dominant process adding nitrogen (N) to the ocean, di-nitrogen (N(2)) fixation, is mediated by prokaryotes (diazotrophs) sensitive to a variety of environmental factors. In particular, it is often assumed that consequential rates of marine N(2) fixation do not occur where concentrations of nitrate (NO(-) (3)) and/or ammonium (NH(+) (4)) exceed 1μM because of the additional energetic cost as...

East-West Distribution of Nutrients and Dissolved Inorganic Carbon in the Northern North Pacific in Autumn

We measured nutrient and dissolved inorganic carbon (DIC) concentrations from west to east across the northern North Pacific Ocean from station K2 to Ocean Station Papa during September and October 2005. At 2000 m depth, silicate levels increased and dissolved oxygen levels decreased from west to east. This trend was attributed to seawater in the layer flowing from west to east in the northern ...

Long-term change in dissolved inorganic nutrients in the heterotrophic Scheldt estuary (Belgium, The Netherlands)

We investigated long-term trends (1965–2002) in dissolved inorganic nutrients in the tidal part of the Scheldt estuary (Belgium, The Netherlands). Annually averaged concentrations of dissolved silicate (DSi), dissolved inorganic nitrogen (DIN), and phosphate (DIP) increased significantly until the mid-1970s, after which they declined linearly at rates of 0.6, 2.9, and 0.3 mmol L21 yr21, respect...
