Concentrations of dissolved organic carbon and particulate organic nitrogen in the Eastern North Pacific

Concentration of Corg ranged from 0.79 to 2.00 mg/l, reaching maximum in the upper productive layers, while that of particulate Norg varied from 0.0018 to 0.037 mg/l, the maximum being in the upper layer (0-100 m).

Water and particulate matter contained 18 amino acids in concentrations varying from 0.150 to 0.177 mg/l in the former and from 0.010 to 0.048 mg/l in the latter. Amino acid composition is variable. Vertical distribution of dissolved Corg and particulate Norg, as well as of dissolved and particulate amino acids is greatly dependent on water dynamics.
