Trace metals in sea water: Sampling and storage methods

Sampling procedures for dissolved trace metals in sea water have progressed to the extent that it is now possible to describe reliable methods for the collection, preservation, and storage of seawater samples. The accumulated experience of a number of workers in the field as well as the results from several intercalibration exercises run by ICES, IOC, and others have been used to determine the best sampling procedures. For many metals a single procedure is adequate, however, for some others separate procedures must be used.
