Some results on using HA in marine chemical investigations are reported. The new modifications of reversed flow-injection manifolds for the determination of dissolved silicate, phosphate, sulfate, sulfide, and manganese(II) in seawater samples and normal flow-injection methods for the determination of total alkalinity, sulfate, and main nutrient-type constituents in interstitial water samples are described. The use of the proposed procedures for obtaining the concentration profiles of some important species in seawater and in interstitial water of marine sediments is shovm. The advantages of FIA techniques for determining the chemical data in a chemical laboratory are demonstrated.

A significant amount of seawater is trapped in the open spaces that exist between the particles in marine sediments. This fluid is termed pore water or interstitial water. Marine sediments are the site of many chemical reactions, such as sulfate reduction, as well as mineral precipitation and dissolution. These sedimentary reactions can alter the major ion ratios. As a result, the chemical composition of pore water is usually quite different from that of seawater. The chemistry of marine sediments is the subject of Part 111.

Fixation of metals as their insoluble sulfides is clearly evident for Fe and is considered the likely method for fixing the other trace metals, except for Mn. The blackened sediment beneath the thin-surface-oxidized layer, the lower SO4/CI ratio than that of marine water, and the presence of pyrite framboids (FeS2> show that sulfate is actively reduced to sulfide in the salt marsh. No discrete metal sulfides, besides pyrite framboids, were detected by microprobe examination however, the simultaneous appearance of S04 and trace metals in the interstitial water of cores stored in air suggests that other trace metals may be present as finely dispersed insoluble sulfides.
