17. total inorganic nitrogen phosphate Fig. 5. Simulated and mean observed values of total inorganic nitrogen and phosphorus in the upper layer at the stations A and B Renk (2000) obtained relationship of phosphate and total inorganic nitrogen in the euphotic layer in the southern Baltic Sea as P=0.072N+0.115. This equation suggests that in the vegetation season the P:N =1:14.1. In the Gdańsk Gulf in this period the N:P=10.8; but in the Gdańsk Deep is 6.5.
