Seventh Intercomparison Exercise on Trace Metals in Sea Water

This is the seventh intercomparison exercise for trace metals in sea water organized by the Marine Chemistry Working Group (MCWG) of the International Council for the Exploration of the Sea (ICES). It is designated as 7/TM/SW. The MCWG at its annual meeting in March 1995 formulated a proposal to conduct an intercomparison exercise for trace metals in coastal sea water in order to give laboratories from the participating countries an opportunity to assess their capabilities regarding this type of environmental analysis. The last study of this nature (6/TM/SW) carried out by the MCWG involved estuarine waters and took place in 1986 (Berman and Boyko, 1988).
