Sentence examples for seawater composition from inspiring English sources

Since that time it is likely that there has been little change in seawater composition.

If fossil-fuel burning were to cease, return to the original state of seawater composition could take thousands of years.

Seawater composition, however, does not evolve directly from the composition of fresh waters and the precipitation of calcium carbonate; other mechanisms that control its composition are involved.

The spatial variability of seawater composition is only partially known, since many areas of the oceans have not been fully sampled.

It appears that the best description of modern seawater composition is that of a chemical system in a dynamic quasi-steady state.

Such covariation is consistent with a model in which fluxes related to alteration of seafloor basalts and continental river runoff vary with time, resulting in variation in seawater composition.

Sequential leaching experiments designed to mobilize secondary carbonates and Fe-oxides show even more unradiogenic Nd isotope ratios in the leachates than the bulk rock and clinopyroxene, approaching seawater compositions (up to 15 εNd units lower than clinopyroxene).
