Summary

Dissolved and particulate humic compounds were determined on samples from three curises in the North Sea in summer 1987. Both groups generally show a negative correlation with salinity indicative of conservative behaviour. In addition, particulate compounds are weakly correlated with total chlorophyll and biogenic opal suggesting phytoplankton to be a secondary source.

Zusammenfassung

Gelöste und partikuläre Huminkomponenten wurden an Proben von drei Fahrten in der Nordsee im Sommer 1987 bestimmt. Beide Gruppen haben im allgemeinen eine negative Beziehung zur Salinität und verhalten sich damit konservativ. Partikuläre Verbindungen sind zusätzlich schwach negativ mit Gesamtchlorophyll und biogenem Opal korreliert, was auf Phytoplankton als eine zweitrangige Quelle hindeutet.

Résumé

Composés humiques dissous et particulaires ont été determiné en échantillons prélevé pendant trois missions sur la Mer du Nord en été 1987. En géneral, les deux groupes montrent une rélation négative avec la salinité indicatif d'un rapport conservatif. De plus il existe une rélation positive entre les composés particulaires et le chlorophyll total et l'opal biogène qui suggère que le phytoplankton peut être une deuxième source de l'importance faible.
