Nitrate horizontal distributions

Horizontal distributions of (a) 02(mLyL), (b) percent saturation of 02(%), (c) phosphate ( j,mol/L), (d) nitrate ( ji,mol/L), and (e) silicate ( ji,mol/L) at 4000 m depth in the worid s major ocean basins. The horizontal distribution of AOU was presented In Figure 8.2. Source After Conkright, M. E., et al. (2002).

Seasonal variation and horizontal distribution of nutrients N, P, and Si DIN (the sum of nitrate, nitrite, and ammonium) and phosphate concentrations did not have an obvious annual, less than annual, or even seasonal cyclical variation. Throughout Jiaozhou Bay in one year, the DIN values were >2.36 pmol/L and the phosphate values were >0.16 pmol/L. Silicate seasonal variation showed a repeated annual cyclic pattern. Every year there was only one highest value of silicate concentration in surmner. Throughout Jiaozhou Bay, silicate values were <2 pmol/L in spring, autumn, and winter, but in summer were >2 pmol/L. For example, at stations 1 and 4 in Jiaozhou Bay, the seasonal variations of DIN concentration, phosphate concentration and silicate concentration were as shown in Figs. 3.60, 3.61, and 3.62. 

Plutonium and fission-product and other inextractable nitrates are present in significant amounts in contactors HA and HS. Their effects on distribution coefficients of nitric acid and uranyl nitrate may be taken into account approximately by reading distribution coefficients of nitric acid or uranyl nitrate given in these figures at a value on the horizontal, x, axis equal to...
