Nutrients potentially limiting the maximal biomass of natural assemblages were studied on the basis of samples collected in late July 1997, along a transect from the mouth of the river Daugava to the central part of the Gulf of Riga. The inorganic nutrient concentrations decreased strongly between the river mouth and the central part of the gulf from 17.3 to &lt;1 mu M NO sub(3) super(-)+NO sub(2) super(-)+NH sub(4) super(+) (DIN), and from 3.5 to 0.03 mu M PO sub(4) super(3-). DIN : PO sub(4) super(3-) increased from 5 to 20. Similar trends occurred for SiO sub(3) super(2-) whose concentration decreased from 72 to 1.6 mu M, but DIN : SiO sub(3) super(2-) only halved. Comparison of DIN : P-PO sub(4) super(3-) ratios (atom : atom) with the Redfield's value...
