| Abstract |
Auto-and crosscorrelation calculations have been applied to leacheable particulate trace metals concentration data (Mn, Fe, Zn and Cu) from the Southern Bight and the Dutch Wadden Sea. Although the amount of data is limited, some features on the dynamic properties of the four metals could be established. The stability of the concentration profile in the two areas decreases in the order Mn, Fe, Zn, Cu. Manganese and iron show a concentration profile that is stable over at least one month in the Southern Bight; moreover as the correlation length is rather large, the existence of an isopattern for Mn and Fe in the Southern Bight is justified. The patterns of particulate Mn and Fe (the same conclusion applies Cu and Zn) are significantly correlated. This indicates that the isopatterns for Mn and Fe have identical gradients in the Southern Bight, suggesting that the particulate (leacheable) Fe and Mn concentrations are influenced by similar processes. Although in the results any isopattern or stable profile for copper and zinc was absent, the observed string correlation suggests that well defined processes must be responsible for the apparent random concentration values of both elements. |
