Changes in 2002

The HELCIM/ICES Steering Group on Quality Assurance of Chemical Measurements in the Baltic Sea (SGQAC) scrutinized the quality assurance part of the HELCOM COMBINE Manual (Part B) at its meeting in February 2002. The Meeting recommended the following restructuring of the pages in order to make the information more logical and reader-friendly. In addition, misprints and other editorial corrections have been made in the documents of the Part B.

In case you have found mistakes or have other comments, please contact the Secretariat, preferably the Professional Secretary Juha-Markku Leppänen (e-mail: juha-markku.leppanen@helcom.fi)
