The quality of control of oceanic carbon dioxide measurements: Preparation and distribution of reference materials. Progress report, January 1, 1993--December 31, 1993

Abstract

The principal goal of this project -- together with a related project funded through the US National Science Foundation -- is to provide a mechanism for quality control that will ensure that seagoing measurement of the oceanic carbon dioxide system made as a part of the Joint Global Ocean Flux Study (JGOFS) studies are comparable and accurate, although made by different laboratories at different times. The strategy we have chosen to achieve this has three principal thrusts: the preparation, certification and distribution of reference materials that investigators can use to evaluate their shipboard data quality; the organization of collaborative studies to test various methods and to help the community in identifying improved analytical approaches; and the preparation and distribution of well written Standard Operating. Procedures describing the analysis of the oceanic carbon dioxide system Active participation in various committees and meetings to proselytize the need for a systematic approach to the quality control of oceanic chemical measurements.
