EMODnet Chemical: QC and QA basic guidelines. Version 1.2.

Abstract

These guidelines are based on a number of inputs to the EMODNET Chemical pilot project, which are acknowledged at the end of this document. It should be noted that to compare small amounts of chemical sample measurements in the same area, over time is a difficult exercise. The challenge of doing this for different instruments, with different techniques, from different institutes, over a much wider area is a challenge in order of magnitudes. This document is provided as a guideline only to demonstrate some of the basic principles that will need to be addressed in order to make the data in the EMODNET Portal as useful as possible. This is a living document and will develop over the period of the project, so please check back for updates on a regular basis.
