Dissolved organic nitrogen enrichment

Miyajima, T., Tanaka, T., and Koike, 1. (2005). Determinig N enrichment of dissolved organic nitrogen in environmental waters by gas chromatography/negative-ion chemical ionization mass spectrometry. Limnol. Oceanogr. Methods 3, 164-173. [Pg.461]

Stable nitrogen isotope compositions are useful tracers of both the source of N to the biomass and the history of the organic nitrogen. The of dissolved N2 in surface waters (c.+ 0.6%o) is slightly enriched compared with atmospheric N2 (0%o) because the heavier gas molecules have a lower vapor pressure and are more soluble in water. In contrast, dissolved NO3 (by far the most abundant form of oxidized inorganic nitrogen in the sea) exhibits values that... [Pg.147]
