Abstract: Sea sediments of various origin have been studied with respect to their electrokinetic potential in seawater of varying salinity. All the sediments tested are negatively charged in seawater and most of them are positively charged in freshwater. Charge reversal occurs between 2 and 6‰ salinity. This could possibly influence the deposition of certain ions and minerals at, or near, river estuaries.
